FAQ
Is this a legally binding signature?
This is a simple graphic signature — an image embedded into the PDF. For legally binding e-signatures, use a qualified digital signing service.
How do I draw a clean signature?
Use a mouse slowly or a stylus on a tablet for the most natural result. You can also upload a photo of your handwritten signature on a white background.
Can I sign multiple places in a document?
Yes, you can add multiple signatures on different pages of the document.
Can I save my signature for reuse?
Signature data is stored locally in your browser and available until you clear the site data.
Can I sign a password-protected PDF?
No. First remove the protection using the 'Decrypt PDF' tool, then add your signature.
Does it work on mobile?
Yes, drawing with a finger on a touchscreen works great. Supported in Chrome, Safari, and Firefox on mobile.
