Compress PDF

Make PDFs smaller so they fit email and upload limits. Compression happens in your browser; the PDF never leaves your device.

Runs in your browser. Your files are never uploaded or stored.

Questions

How much smaller will my PDF get?

Scans and PDFs full of photos often shrink by 50–90%. PDFs that are mostly text are usually small already.

Are my files uploaded?

No. The tool runs inside your browser, and the page is blocked from sending data anywhere. You can check by turning off your internet connection: it keeps working.
