Questions

Is it free?

Yes. Every tool is free and unlimited, with no page limit and no account required.

Are my files uploaded?

No. Sign PDF runs entirely in your browser, so your document never leaves your device.

Is there a file size limit?

There is no limit we impose, but everything runs in your browser's memory, so very large files are bounded by your device rather than by us. A few hundred pages is comfortable on a laptop; phones manage less.

Does it work on my phone?

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