About Compression
Compression was built for the moment you just need to handle this task and move on — no signup, no upload to a third-party server. Processing runs locally in your browser using modern Web APIs. Nothing is uploaded, nothing is logged, and there is no quota to worry about for casual use. Like everything else in the utility collection, it is free, ad-light, and works on mobile as well as desktop.
