Frequently asked questions

Is Sign PDF free?

Yes. Sign PDF is completely free, with no account, no sign-up, no watermark added to your files and no daily limit.

Are my files uploaded when I use Sign PDF?

No. The PDF is opened and processed inside your browser with JavaScript, so the file never leaves your device and is not stored on any server.

Is this a legally binding digital signature?

It adds a visible signature (an electronic signature image), not a certificate-based digital signature. Whether that is enough depends on your country and the document; check the requirements for contracts.

How do I add my handwritten signature?

Sign on white paper, take a photo or scan, crop it and save it as PNG, then choose Image signature and upload it.

Does it work on a phone or tablet?

Yes. It works in current versions of Chrome, Safari, Edge and Firefox on desktop, Android and iOS. Nothing needs to be installed.
