Frequently asked

What does Sign PDF do?

Add your signature to contracts, forms and letters in seconds. Draw it with your finger or mouse, type it in a handwriting font or upload a photo of it. Then drag it into place and resize it.

The tool works entirely inside your web browser. Your files are processed on your own device and are never uploaded to a server, so they stay private. Closing the tab removes everything.

This adds a visual (handwritten-style) signature, not a certificate-based digital signature.

Sign PDF – common questions

Is this a legally valid electronic signature?

It adds a visual electronic signature, like signing a printout. That is accepted for many everyday documents. It is not a certificate-based digital signature (PKI), which some legal and government processes require.

Can I sign on my phone?

Yes. Draw the signature with your finger. The editor toolbar sits at the bottom of the screen on phones.

Can I add the date and initials?

Yes. Use the Text tool for the date or name, and add the signature again on other pages for initials.

Is my PDF uploaded?

Nothing is uploaded: the file is processed inside your browser and never leaves your device.
