About Image Compressor

Image Compressor is a free online tool that lets you compress one or many jpg, png or webp images in your browser, then download all as a zip — straight from your browser, with no software to install, no sign-up, and no watermarks. It runs on Windows, Mac, Linux, Android, and iOS, so you can use it on whatever device you happen to have to hand.

It's perfect for shrinking files that are too large to email, upload to a website, or attach to a form. Image Compressor analyses your file and removes wasted data while preserving the visual quality, so the result looks the same but downloads and shares far faster. Files and data are processed securely and removed automatically afterwards, and many steps run entirely on your own device for extra privacy. Because Image Compressor is completely free and unlimited, you can use it as often as you need for work, study, or personal projects.
