about this tool

Reduce PDF file size while keeping it readable — optimize for email, web uploads, and storage, all in your browser without giving up your privacy

Online tools often ask you to upload your files to their servers first. For anything sensitive, that's a real privacy concern. This tool takes a different route — everything runs entirely inside your browser.
