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.

Producer is the technical tool that generated the PDF. The library used here sets this automatically and it cannot be changed from the UI.

Enter comma separated values, for example: invoice, 2026, Q1.
