Questions about the PDF compressor

Is the PDF compressor free?

Yes, completely free, with no sign-up, no limits on use and no watermark.

Are my files uploaded to a server?

No. Your files are processed inside your browser on your own phone or computer, so they never leave your device.

Does it work on my phone?

Yes. It works in any modern browser on Android, iPhone, Windows and Mac, with nothing to install.

How much smaller will my PDF get?

Scanned PDFs and PDFs full of photos often shrink by 50–90%. PDFs that are mostly text are already small, so the Light option keeps them sharp and selectable.
