Free signing, with no features held back

PrivaPDF's signature tool isn't a stripped-down free version pushing you toward payment — drawing, typing, or uploading a signature image, placing it, and downloading the signed PDF is fully available for free, with no daily cap.

Since it runs in your browser rather than through an upload-and-wait cycle, signing a document online here is often faster than the "free" tier of upload-based e-signature platforms, which typically queue your file through their servers before returning a result.

Don't trust us.
Verify it yourself.

Open DevTools → Network while converting. You'll see zero outbound requests. Every byte stays inside your browser tab.

Common questions

Is my file uploaded to a server?

No. All processing happens entirely in your browser using WebAssembly. Your file never leaves your device.

Is a browser-drawn signature legally valid?

In most countries, an electronic signature is legally valid for everyday documents. For regulated industries requiring qualified digital signatures (QES), you may need a certified provider.

Is it really free?

Yes. Every tool is free with no daily limit. No account or credit card required.

Does this work offline?

Yes. Once the page is loaded, you can disconnect from the internet and the tool will still work perfectly.
