about this tool

Compress Image without giving up your privacy

Online tools often ask you to upload your files before processing them. For anything sensitive — contracts, statements, personal documents — that's a real privacy concern. This tool takes a different route: everything runs entirely in your browser. Your files are opened locally, processed in your device's memory, and handed back to you. No copy is ever transmitted to a server, which means it works offline too.

Privacy by design. This tool loads once and runs entirely in your browser tab. Close the tab and nothing remains. No cookies, no tracking, no server — just the utility you need, instantly.
