Introduction

Using AI to improve the information richness of images may seem like a thing of the future but it actually works when it comes to upscaling or denoising them.

The advances in deep learning-based models, especially in computer vision over the last years made the development of image upscalers possible.

It does not matter if you want to improve the resolution of a photograph you took years ago or digital artwork, nowadays any kind of image can be upscaled in terms of resolution.

This post intends to provide some online resources one of which is more technical but flexible and others are plug-and-play solutions for easy use.

For all examples shown below, I have used the same scaled-down jpeg image so you can compare the quality of the image upscaling tools.

3. Zyro

Zyro’s AI Image Upscaler is a simple online tool that allows you to input an arbitrary image, photograph, painting, or anything else and will return a higher-resolution version of it within a few seconds.

The website is build in an simple manner making it easy for everyone to use.

As you can see below you can even compare the original image to the new upscaled one.

Visit zyro.com and enter your first jpeg or png to test it out.

2. Fotor

Another great tool for high-quality upscaling is Fotor. As Zyro it is very user-friendly with a nice interface that lets you do more than just upscaling your images.

The website itself is built like a photoshopping tool that enables next to image-upscaling also AI-based features like object or background removal.

The comparison between the original and upscaled image below seems even more impressive than the one presented by Zyro.

Check out Fotor and explore its capabilities.

1. SwinIR (my personal favorite)

Going over to a more technical tool, SwinIR, developed by Jingyun Liang, provides extreme upscaling and image-denoising capabilities with its transformer-based neural network architecture.

I believe that SwinIR is currently the best method to upscale and denoise images.

In the image below you can see the tweaks you can make to the image you put in. You can pick a task such as extreme upscaling, image denoising, and others and additionally tweak task-specific parameters.

SwinIR served on Replicate.com

Below you can see the detailed comparison between the original and upscaled image which in my point of view is just magnificent.
