Summary: AI Image Compression Tools help websites improve their performance by reducing the size of images. This can improve user experience and SEO by decreasing page loading time. These tools use various approaches such as lossless compression, lossy compression, and deep learning.

Making page loading faster is essential for website performance. No matter if you are running an online store or updating blogs, faster page speed can help improve user experience and SEO.

However, keeping page speed in less than 2 seconds is a bit tricky since there are many factors that would impact page performance. There are different approaches such as redirecting website, eliminating JavaScript or CSS and making HTTP requests. Yet, one basic but equally important thing is about the size of your images. In particular, high-quality images in smaller size are favored by Google as well as your audience. This is also good news for non-techies because page speed can be faster simply by compressing images using free tools.

Top 5 AI Image Compression Tools for Web

For those interested in deep learning image compression, this image compression tools review is a must-read because we will also introduce several AI-powered image compressors.


Compression.AI differs from conventional image compression tools by using machine learning. It claims to train its neural networks with over 10M images from the internet. This makes it possible to assign different bitrates to different parts of an image for adaptive effects.

However, this AI image compressor only offers API, targeting business instead of individuals. To access the API service, you will need to leave personal information including email and company name.



  • Use neural networks for adaptive image compression
  • Provide API service


  • Not available online
  • Poor customer service
  • Lack free trial
  • Personal information is needed before contacting the service provider

2.High Compress

High Compress makes online image compression as easy as one click. More tools are available, such as plugin and API. For techies who opt for AI technology, this image compression tool can be a good choice. 3 different modes enable you to either play with lossless image compression or lossy image compression. Compressing your image up to 95% is possible but at the cost of quality even if the tool is powered by AI.
