Improve ASP.NET Site Performance via Optimized Images


Fast loading time of websites can bring visitors good experience. Webmasters need to optimize websites so as to speed up the web applications’ loading time. Images, as one of the big resources-consuming projects, play an important role in website design and performance and must be considered firstly into the optimized plan. What’s more, for most of the ASP.NET websites users, optimizing images can improve the site performance largely and decrease the websites requests of hosting service.

 Why We Need to Optimize Images?

Actually, the loading time of all the websites is mainly decided by the images. That is why we sometimes can see the text quickly but need to wait the loading for images during visiting one website. And usually, large-sized images will occupy a mass of hosting space and RAM which will have higher requests in bandwidth, website loading time, conversation rates, data needed…

In addition, during the website management, we can find that there is size limitation when we upload images. Hence, some large-sized images cannot be uploaded or image qualities will be influenced due to improper size.

What’s more, as we all know, the mobile data is not cheap, so those websites that also support mobile devices, optimized images can reduce the requests of data needed.

Optimized images not only can make better impression on users but also bring much convenience for webmasters. So, if you would like to have access the website in a fast speed and reduce the stress of websites operation, we should reduce the file size of the images firstly by optimizing images.

How to Optimize Images?

Although optimizing images is so important, most of the webmasters still do not know how to do and even ignore it in the process of websites management. In this article, we will recommend several Image Optimizer with great optimization algorithms to help webmasters optimize images but will not make any unnecessary influence.


As one of the star product of Gulp, Gulp-imagemin can be used to compress the image files including the formats of PNG, JPEG, GIF and SVG. Once getting installed in websites, Gulp-imagemin will automatically optimize images during the construction of websites in build time.

Gulp-imagemin uses industry standard optimization algorithms, supporting both lossy and lossless optimization. Besides, it has high securities and can be chosen and created for free since it is open source. For those users of Gulp, Gulp-imagemin will be more easy to use and absolutely their perfect choice.

While, for the beginners, there may be some errors in the process of configuration since it needs some professional knowledge. In addition, as part of the site building, it may increase the time in some ways. The most important is that is not possible for those dynamically added images.

Visual Studio Image Optimizer

In Visual Studio, Image Optimizer uses special compression technique – MagiCompress, creating the best images including JPG, GIF, PNG, BMP, TIF etc.. It can maximum reduce 50% size of the images so to make much room for other files and decrease the loading time.

Same with Gulp-imagemin, Image Optimizer is also open source, supporting both lossy and lossless optimization, having strong optimization algorithms with high industry standards. The good news is that Visual Studio Image Optimizer does not need to be configured. Also, it is easy to use after installation.

However, Visual Studio Image Optimizer does not support build time and it also cannot optimize dynamically added images.

Azure Image Optimizer

With the same optimization algorithms of Image Optimizer, Azure Image Optimizer is very appropriate for any ASP.NET application and it can optimize the images automatically after configuration without any change of codes. And before installing Azure Image Optimizer, users are requested to have the Azure subscription. But don’t worry since it is free for all the users.

With all the same advantages of Gulp-imagemin and Visual Studio Image Optimizer, Azure Image Optimizer is so easy to use and can be set up and canceled anytime. What needs to be emphasized is that Azure Image Optimizer once of the scarce optimized software that can optimize dynamically added images.

While, its work platform is only limited in Azure App Service, which means users have to install the Azure App Service in advance.


In conclusion, the images optimizers can bring many advantages in the website construction. Except for the above three options, there are some more images optimizers which can help users to decrease the hosting service requests. Although you have all these optimizers to improve the performance of your sites, you need a reliable ASP.NET hosting service to support it. Yes, that’s what Host4ASP.NET has been dedicated to doing along the way.
