Anyway, let’s get started with the upscalers!

1. StockPhotos Upscaler

Upscaler

StockPhotos Upscaler is the best overall solution for enhancing and upscaling images.

This web-based application charges you $0.1 per upscale. Of course, you can try the tool for free if you want to be sure about the quality of work before.

For instance, I tried it with blurry images and figured it did not do a great job. But once I tried the tool with low-res images, it performed perfectly.

StockPhoto Upscaler is easy to use. There are great features you can use besides upscaling the imagery. For instance, you can choose to scale between 2x, 4x, and 8x.

Then you can also define smoothing elements to optimize the upscaled output. The AI that powers the upscaler detects low resolution, noise, and blur from images. This means you might have to tweak the settings to make the right type of enhancement.

You can choose between these three image-enhancement options:

  • High-fidelity
  • Artifact removal
  • Ironed out

This is just to prevent removing artifacts from images with no artifacts, for instance.

Now that you know what the tool is all about, let’s give it a try or two.

Here is an example. The upper image below is a low-quality image. The bottom image is an upscaled version by 200%.

Before and after upscaling

If you look closely, you can see that the bottom image is indeed sharper than the above image.

But let’s see another example.

If you have a low enough image resolution, here is what happens when upscaling:

Before and after upscaling

As you can tell, the image quality went up but it doesn’t still look magical, does it?

Unfortunately, this issue is still present in all the image upscalers. If the quality is low enough, the tools cannot do wonders with it. This is the state-of-the-art in AI image enhancement.

At the moment, the tools are impressive, but not magical (yet). Although you can only expect these tools to get better over time.

Key Features

  • Upscale images up to 800% of the original size.
  • Remove noise and other artifacts from images.
  • 3 smoothing options:
  • Artifact removal
  • High fidelity
  • Ironing out
  • Upscale images in bulk to save time and manual labor.
  • There is live chat support available if you have questions.

Pros

  • There is a free trial you can use to upscale up to three images.
  • Scaling up to 800% of the original size looks great and does wonders for images with low detail.
  • The purchased upscales are usable for up to 12 months.
  • The pricing is simple. You pay for a batch of upscales.

Cons

  • Stockphoto upscaler is impressive but if the image quality is low enough, there’s not much you can do about it. Also, if the images are blurry, this tool won’t be able to resolve them well.
  • This tool doesn’t do wonders when it comes to removing blur from images.

Pricing

You can try the tool with 3 free upscales!

Besides that, there are two paid plans you can choose between:

  • Standard: 20 upscales for $7.
  • Premium: 100 upscales for $15.

Both plans are a one-time fee and the upscales expire after 12 months.

2. VideoProc Image Upscaler

VideoProc Converter AI provides a simple and fast solution for photographers or anyone aiming to enhance their image quality by upscaling resolution to stunning 8K/10K.

This is particularly beneficial for refining aging photos, low-resolution images captured by vintage cameras, AI ART, or any images generated by Midjourney, DALL-E, and more.

Whether you seek print-ready photos or wish to upscale images for advanced editing and storage, VideoProc Converter AI is your invaluable ally.

Furthermore, VideoProc Converter AI empowers you to elevate the quality of your video content, be it low-quality footage, recordings, DVDs/VHS/DV, or SD-resolution videos downloaded from the internet.

It has the capability to upscale resolution by 2X, 3X, or 4X, optimized for editing, storage, or playback on larger screens, delivering remarkable sharpness.

My Experience

Let me show you how the tool works. Because it’s a video converter, it might be a bit confusing on how to upscale images. But that’s an easy task.

This tool gives such epic results it’s worth trying.

Step 1: Open VideoProc Converter AI and click on ‘Super Resolution’.

Step 2: Click “Add Media” to load your images or videos, or directly drag them into this AI enhancer

Step 3: Choose your desired upscaling level (2X, 3X, 4X) and preview it instantly.

Step 4: Click ‘Run’ to export the enhanced images or videos

Tip: Before exporting, you can fine-tune some settings, such as selecting the output photo/video format, codec, quality level, de-noise, etc.

Pros

  • User-friendliness: Tailored for beginners, ensuring accessibility for a wide range of users.
  • Lower Hardware Requirements: Demands less from your hardware compared to most AI video tools, making it accessible to a broader audience.

  • Most Affordable AI Enhancer: VideoProc Converter AI is one of the most budget-friendly AI photo/video enhancer software on the market, priced at only $29.95 for a Lifetime License with free upgrades forever.

Cons

  • Expensive: This tool is for serious business. It’s not an average online converter tool with decent results, but it’s full-blown AI software. This makes it expensive.
  • Not Online Software: Unlike most tools on this list, this one is not an online-based software. You need to install it to use it!
  • Limited Features for Mac: This will change in the next month or two, but VideoProc still has some limitations in the AI features for Mac users.

Honorable Feature Mentions

As mentioned before, VideoProc is a high-quality AI video enhancer. So it’s not just an image upscaling solution.

One of the features I must mention is the AI frame interpolation feature. This picture illustrates it perfectly.

Similarly, you can reduce shakiness from your videos (or images) easily:

Recording stable, shake-free videos can be a challenge, especially when using devices like GoPro, phones, drones, or handheld cameras.

VideoProc Converter AI provides intelligent video stabilization to make your videos look stunning.

Bottom Line

VideoProc Converter AI does an epic job with images. But it’s even better for videos. Especially if you’re planning to use AI to enhance videos besides images, I must suggest using this one. It’s for serious content creators!

3. Winxvideo AI

From its name, Winxvideo AI appears to be an AI video tool. However, I was pleasantly surprised to find that it also featured a built-in Image AI function

This image upscaler allows you to increase image resolution by 2x, 3x, or even 4x.

Let’s see how it performs.

My Experience with Winxvideo AI

Based on my tests, it can upscale images to 4K, 8K, and even 10K. To achieve higher resolutions, you can re-upscale already-upscaled photos by Winxvideo.

You can even do upscaling to meet your needs when it comes to printing images!

In addition, it offers an “Enhance Image (1X)” option that lets you improve image quality without increasing the resolution, by removing blur, noise, pixels, and compression artifacts.

By clicking the drop-down menu labeled ‘Type’, I discovered that this AI image enhancer supports not only anime images but also real-world images, such as portraits, animals, architecture, and landscapes. When selecting ‘Anime’, users can adjust the denoise level to suit their preferences.

Here are some examples of my tests. I have tried an anime, a portrait, and a landscape image, and upscaled each by 2x. The results of the tests show a significant improvement in the quality of each image, with increased clarity.

Here’s an example where I used WinxVideo to upscale an anime picture:

As you can tell, the quality difference is drastic.

Example of upscaling portrait with Winxvideo AI:

All the noise is gone. That’s impressive, isn’t it?

And here’s one more example of upscaling landscape picture with Winxvideo AI:

This is the most impressive one in my eyes. The quality goes from what I would say 3/10 to 7/10 or 8/10.

Key Feature

  • Upscale image resolution by 2x, 3x, or 4x.
  • Reduce blur, noise, and artifacts for sharper, clearer visuals.

4. PiktID SuperID

SuperID by Piktid is an AI photo enhancer designed specifically to improve the quality of facial details in images.

It’s ideal for various users, including professionals in photography, graphic design, and e-commerce. SuperID offers features like fast and super upscaling, time-saving batch image processing, and cost-effective solutions for enhancing image resolution.

What it especially stands out for is that the expressions and identities remain intact for its focus on crystal-clear facial details, ease of use with various image formats, and options for immediate or enhanced download quality.

For instance, take a look at this blurry image that I took from Unsplash:

Now don’t get me wrong, based on the look of this original image, I know it’s meant to be blurry like that.

But I find this also a perfect example to try upscaling to remove the blur and artifacts.

So let’s feed this into PiktID SuperID. First, I will try the 2x upscaler mode:

Pretty cool! All the blur and artifacts are gone now. But this is just the 2x upscaled version.

Next, let’s do one more and try to upscale it by 4x.

Now this is impressive. The quality is so much better in this one. The artifacts and blur are gone.

What a cool tool we have over here!

Key Features

  • Upscale images up to 400% of the original size
  • Free trial to test the tool extensively
  • API for programmers to connect their app to this app to use the cool AI features

Pros

  • Works really great with some face images and doesn’t look artificial at all
  • You can choose 2x or 4x upscale based on your needs
  • There are advanced settings for each upscaling
  • The UI makes it relatively easy to use
  • There are tons of AI features in the mix you should try as well! For example, there’s the Face Anonymization and Editing software you must test.

Cons

  • Some images end up looking cartoonish, but this depends on the mode being used.
  • The UI has some slightly confusing parts, for instance, the images disappear and the colors make parts of the UI hard to read.
  • Pricey, although it comes with the highest quality upscaling :)

Pricing

  • Subscription (default: 0.5€ per credit)
  • Pay as you go (default: 1.59€ per credit)

#5 Imglarger AI

Imglarger is a one-click solution for improving image quality and crispiness. This tool can 2x, 4x, and 8x your image quality.

You can try the 2x and 4x features for free here.

Let me show you how the tool performs with different inputs.

Here’s the original image I’m using:

And here’s the upscaled version:

Now, that’s impressive, but it’s only 2x upscaled, that is, 2x bigger than the original one.

Just as a comparison, here’s what the input vs. output look against one another:

Let’s try the 4x and 8x improvers next.

With the same input image, here’s the 4x upscaled version:

Looks very smooth and crisp! Let’s do a side-by-side comparison with it too:

Then last but not least, let’s do an 8x upscale. Here’s what the 8x upscaled image looks like:

That’s some solid quality right there. Let’s do a side-by-side comparison one more time:

As you can see, the difference is like a day and night. I love the fact that the demo images met my expectations (unlike most products in this space.)

Pros

  • Fast. The tool does its AI upscaling magic in just 15–30 seconds.
  • Accurate. The tool not only makes the image larger, but it also makes it look sharper and crispier on top of the quality improvements. In most images, this makes them shine in a completely different way.
  • Free. You can test the 2x and 4x upscale features for free to get an idea of how good a tool it is. You just need an account and you will get 10 free credits.

Cons

  • UX. I was confused when using the tool because it names the upscaled image with the same name as the original one.
  • Faces. The AI cannot reliably unblur or upscale faces. It averages out all the intricate details of human faces. But this is a problem with basically all the upscaler tools that you will meet today.
  • Saving. Although you can download the upscaled images, the tools don’t store them anywhere (at least I couldn’t find where the upscaled images would go.)

Pricing

  • Free: $0/mo
  • Starter: $4.9/mo
  • Premium: $9.9/mo
  • Advanced: $19/mo

6. Gigapixel AI

Gigapixel AI upscaler

Topaz Gigapixel AI is a complete package for AI image enhancement. Not only does this software upscale images for you but it also does noise and shake-reduction. You can also use it to resolve images with blur in them.

The tool is powered by the latest advancements in AI image processing and the results are accurate.

Gigapixel’s image processing AI has trained itself with an array of millions of images. This way it has learned the concepts such as noise and blur. More importantly, thanks to the vast training experience, this tool knows how to handle those artifacts.

With Gigapixel, you can quite literally make hand-held photos look like professional images captured on a tripod.

The main reason Gigapixel is on this list is the ability to upscale images. The detail you have lost in the image-capturing process can be intelligently added back to the image using Gigapixel’s AI.

Notice that the pixel information that is lost cannot be revived per se, but the AI can predict what it would look like.

Anyway, here is an example of improving the detail of an image:

Gigapixel before and after upscaling

As you can tell, the difference is quite awesome.

Notice that even though Gigapixel is a great tool, it doesn’t always succeed. If an image is too small, too blurry, or too noisy, there is not much you can do about it.

Key Features

  • Shake reduction
  • Noise reduction
  • Upscaling up to 600% of the original size
  • A downloadable tool for Mac and Windows
  • Easy to use
  • Bulk enhancing/upscaling capabilities

Pros

  • Very precise enhancing and upscaling capabilities to revive your old and low-quality photos.
  • The shake reduction tools make shaky photos look more stable.
  • Upscaling is possible up to 600% of the original image size.
  • You can upscale images in bulk mode. This way you don’t have to upscale images individually by hand which saves a lot of time.

Cons

  • The app is downloadable, not an online editor like many other photo enhancers are.
  • Doesn’t work on Linux.
  • There is a free trial but you need to sign up to use the service. This is annoying as most of the best AI upscalers have a no-signup free trial.

Pricing

The pricing model of this tool is simple:

  • Free trial: Try the tool for free. All you need to do to activate the trial is to sign up with your email address.
  • $99.99 one-time payment: Get full access to the software and its updates.

7. Vance AI

Vance AI image upscaler

Vance AI is a one-of-a-kind image upscaler tool that lets you scale your image up by 800%. This makes low-resolution images look great again.

Pricing

There are three plans available to Vance AI:

  • Free: $0/month
  • Basic: $9.90/month
  • Pro: $19.90/month

The free plan gives you a great idea of the product. If you are looking for top-level upscaling or are a more rigorous user, you might want to club up to a paid plan.

8. UpScale

Upscale

UpScale is a great image upscaling tool offered by PixlBin. This tool lets you upscale and enhance images for free on a web-based application.

Needless to say, this tool is easy to use and access. You don’t need to sign up to use the tool and its great features.

The maximum image size for upscaling is 1500x1500!

Let’s take a look at three examples. Here I’ve converted an image from the desert on three different occasions, each time using a smaller and less-detailed image.

Here is the first try:

Upscale before and after upscaling example

As you can tell, the tool does a great job of making the image appear smoother and of higher detail.

Let’s take a look at the next round with a smaller starting image:

Upscale another example before and after upscaling

Wow! The tool makes great work again. The resulting image is much smoother and appears to have more detail once again.

Now let’s try to upscale an even smaller and less-detailed image:

Uspcale third example of before and after upscaling

Here the problem starts to arise. The resulting image looks much better but it starts to have cartoon or painting-like features so it doesn’t look like a photo anymore.

As stated earlier, this is no surprise. The AI models aren’t yet clever enough to fully understand what’s going on in the less detailed images even though the human eye can. But it will only get better as time passes.

In 10 years it might be that image upscalers can do magical upscaling compared to state-of-the-art upscaling.

Key Features

  • Image upscaling up to 4x of the original size.
  • Easy-to-use interface and workflow.
  • Email support for questions.
  • Third-party integrations, webhooks, and SDKs for different programming languages.
  • Bulk upscaling for saving manual work.

Pros

  • You can upscale your images for free for up to 50 images. This is a great deal most upscalers don’t offer.
  • You can pay for the bulk mode to save manual labor when it comes to upscaling multiple images.
  • Upscale has other cool solutions, such as a background eraser, a watermark eraser, and a media shrink tool.

Cons

  • There are sometimes unexpected errors when scaling images. For instance, if your image scales up too big, it causes a problem even if the original image was the right size.
  • The upscaling is only possible for 4x of the original images. Some tools offer 8x or even up to 16x.

Pricing

Upscale pricing

The UpScale plans are:

  • Free: $0/month
  • Starter: $29/month
  • Basic: $89/month
  • Premium: $299/month

The free plan includes upscaling up to 50 images which is more than most tools offer!

9. Let’s Enhance

10. Deep Image AI

Deep Image AI image upscaler

Deep Image is a great upscaling tool that is ideal for those looking to scale images up in bulk.

Here is an example image before and after upscaling.

Deep image example before and after upscaling

As you can tell, the difference is clear. The leftmost image looks blurry and low-quality. The right-most image looks fresh and detailed as if it was taken on a high-resolution camera.

Thanks to the AI algorithms behind the scenes, the image upscaling ends up looking natural.

The size limit of an upscaled image is 5000 x 5000 pixels (or 25 megapixels). This applies to both registered and unregistered users.

Icons8 before and after upscaling example images

From the above image, you can see how well the AI performs, though. Look at the mountains in the background.

Those look so blurred on the left-hand side. On the right-hand side, the upscaling has made the image much higher in detail.

To upscale an image with icons8, follow these three steps:

  • Free download of the upscaled images.

Pros

  • There is a free trial version you can access without signup. Although this version will add watermarks to the images.
  • The tool is extremely easy to use and access. Just enter the website and upscale an image. It will only take seconds.

Cons

  • Watermarks in the freely generated images.
  • The upscaling factor is 4 at most. This means you can only 4x your images, while other tools let you do up to 8x.

Pricing

12. Waifu2x

waifu2x

Waifu2x is an anime-focused image upscaler. Despite its vintage looks, the tool uses neural networks to scale images up. The results are surprisingly great when you consider the old look and clunky UI of the tool.

Even though the tool is geared toward anime consumers, it can also upscale any type of photo.

Waifu2x also takes care of removing noise from the images it upscales. Besides, you can simply enter the URL of the image you want to compress. This means you don’t need to download drag and drop the file into the tool. Instead, the tool fetches the image behind the URL and upscales it for you.

Here is an example of an image I upscaled with Waifu2x. On the left, you see the original image and on the right, you can see the upscaled version. Although the difference is not big, it’s still there.

waifu2x before and after upscaling

Key Features

Let’s take a look at the key features of Waifu2x

  • 2x upscaling specialized in anime.
  • 2x upscaling in all types of photos.
  • Noise reduction capabilities.
  • Upscale images behind a URL.
  • Waifu2x is an open-source project.

Pros

  • The tool is free to use. Even though it targets anime images, it works well for regular photos too. It even has a photo section dedicated to upscaling photos!
  • Great noise reduction capabilities for basic use.
  • It’s nice you can upscale images directly behind a URL instead of downloading the images to your device and then uploading them to the tool.

Cons

  • The upscaling is limited to only 2x, which is very little compared to other upscalers on this list.
  • Old UI. I believe the tool doesn’t get frequent updates anymore. For instance, their website is missing an SSL certificate and looks old. Nonetheless, the tool works well, although limited to 2x scaling.

Pricing

Waifu2x is free to use!

13. BigJPG

BigJPG AI image upscaler

Do you have some low-resolution images, illustrations, or anime pictures you want to enhance or upscale?

BigJPG is a great solution for these types of imagery.

This tool is one of the most popular anime image upscalers that is known to produce great results in scaling up low-resolution anime images and illustrations.

Even though the tool is geared toward anime, you can use it on any other picture or illustration as well.

Here is an example of a low-res image I upscaled using the tool. The left-hand side is the original image and the right-hand side is the upscaled version:

BigJPG example

BigJPG is also a great option for developers because there is an API available.

BigJPG does great during the upscaling process. It fills colors, details, and edges in a professional way leaving you with quality images with no data loss.

Notice that the tool limits the scaling only to 3000x3000 images which is more than most tools on this list do.

Key Features

Here are some of the most notable features of the BigJPG image upscaler solution:

  • AI-based image upscaling uses a neural network to predict how the image looks in better detail.
  • Bulk image upscaling and enhancing to save manual work uploading the images.
  • Windows, Mac, and Android support.
  • The easy-to-use interface takes no time to try and use.
  • 10MB image support.

Pros

  • This tool is free to use. It lives on a browser so you don’t have to install any additional software. All you need to do is go to their website and upscale images.
  • Supports upscaling in batches which saves a lot of manual work.
  • Does 4k upscaling without loss of quality.
  • Upload images up to 3000x3000 in size. This is more than your typical AI upscaler does.

Cons

  • I think the results of this tool are great but not that impressive on regular images, as you can see from the example above.

Pricing

The tool is free to use!

How Do AI Image Upscalers Work?

A low-resolution image has fewer pixels than a high-resolution one. This makes low-res images look blurry or low-quality.

To improve the image quality, upscaling needs to take place.

To accurately upscale an image, one would need to add information to the image in the form of pixels. Naturally, this is impossible without taking a new picture.

The second best alternative is to use some image upscaling techniques.

Regular upscaling refers to increasing the resolution of a low-resolution image to make its visual quality better.

But an AI-based upscaling takes a completely different approach. Instead of trying to increase the quality of an image by boosting the resolution, AI uses deep learning models to predict the missing pixels.

More specifically an AI image upscaler takes a low-resolution image as input. It then uses a neural network to generate an image that would downscale to look like the original input image.

To make this happen, the AI upscaler must have been trained with millions of images to accurately predict the high-resolution appearance of the image.

The Future of Image Upscaling

AI upscaling is making its way. You can expect the solutions to only improve over time. This is thanks to the rapid developments in AI and image creation.

For example, today, the face upscaling isn’t quite on point.

But who knows what those will look like in 2–3 years with this pace of development?

The reason why the AI still fails quite drastically is because it’s not adding information—it’s predicting it!

Summary

That’s it for the reviews! Today you learned about the best AI upscaling tools for making your low-res images look better.

These days AI makes it possible to upscale images to improve the quality when making them bigger. In short, the AI predicts how the image would look in a high-detail version. This is unlike the traditional upscaling which just tweaks contrast or sharpness.

To make an image upscaler work, companies have developed AI algorithms that are trained with millions of images. The idea of an image upscaler is that it recognizes what happens in the image and predicts how it would look in more detail.

To choose the best AI image upscaler, make sure the solution has:

  • Free trial
  • Supports up to 800% scale-up
  • Supports bulk upscaling
  • Corrects noise, blur, and other artifacts

The best solutions that meet these requirements are StockPhoto Upscaler, Gigapixel AI, and Vance AI.

Thanks for reading. I hope you found a suitable upscaling tool for making the images look greater.
