Is 18PDF really free?

Yes. All 18 tools are free to use, with no signup, no file size limit, and no watermarks on output.

Are my files uploaded to a server?

No. Every operation runs entirely in your browser using WebAssembly. Your files never leave your device.

No. There is no signup, no login, and no tracking. Open the tool and start working immediately.

There are no artificial limits. The only constraint is the memory of your device, since processing happens locally.

You specify the number of points to trim from the top, right, bottom, and left of every page.

Only the visible area is reduced. Hidden content outside the crop box is still present in the file.
