How to optimize images in .Net Applications?

In this rapid paced technology dependent world, patience has flown out of the window. Everyone wants everything to be quick, especially online. In fact, a lot of websites lose users just because they don’t load fast enough while their competitors do.

Most of the times, in web applications, pages are often rendered slow because of the images they contain. High quality images, which are crucial for any website, are usually larger in size and hence take a lot of time to load completely. This slows down the load time of the whole page.

Although, Asp.Net applications provide a lot of features to avoid slow loading of pages, there is always room to improve even more. In this article, we will take a look at 4 extensions of .Net applications that optimize the images of your website without affecting the quality in any way and help the page load a lot faster.

Visual Studio Image Optimizer

Visual Studio is one of the most popular integrated development environments built by Microsoft. It is used extensively to build .Net based web sites, apps, mobile apps etc.

Applications created on Visual Studio can use the Visual Studio Image Optimizer extension to optimize their images. Its really simple to use and makes use of some strong optimization algorithms.

Azure Image Optimizer

With the evolution of cloud services, Microsoft came out with Azure, a cloud computing service to build, test, deploy and manage Asp.Net applications through Microsoft’s global data centers.

Just like the Image optimizer of Visual studio, the Azure Image optimizer also uses strong algorithms to optimize your images. All you have to do is to install the Azure Image Optimizer NuGet package into your Asp.Net application and the images will be optimized automatically without any code changes.


Gulp.js or simply Gulp, is an open source JavaScript toolkit that is used to automate time-consuming and repetitive tasks required for web development, especially if you’re using .Net.

If you’re using Gulp, you have an option to use the Gulp-Imagemin package for your application. This however, requires some configuration which would be better handled by experienced dot net developers. Once configured, it automatically optimizes your images as part of your build.


Similar to Gulp, Grunt is another open source JavaScript based toolkit that is often used with Asp.Net applications to perform frequent tasks like minification, compilation, unit testing and linting.

The Grunt ecosystem includes over 5000 plugins out of which, the Grunt-Contrib-Imagemin is the one that helps you optimize your applications images. You will have to install the plugin and include it’s functionality into your workflow.

So these were a few options that you can make use of to optimize the images of your pages to improve your apps performance.

The performance is not the only advantage you get with this. the reduced file size of the images also reduces the weight of the website which in turn requires lesser bandwidth, cheaper hosting and lesser data for for loading on mobile devices. Optimized images are much better for your users and therefore for you.
