Frequently asked questions
How do I position my signature?
Use the position and width fields to set where the signature lands on the page, as a percentage of the page size. The default places it in the lower-right area.
Is my PDF uploaded to a server?
No. The PDF and your drawn signature are combined entirely in your browser using JavaScript - nothing leaves your device.
Is this a legally binding electronic signature?
This tool visually places a drawn signature image onto the page - it does not add cryptographic signing or identity verification, so it may not meet the requirements for legally binding e-signatures in every context.
Can I sign more than one page?
This tool signs one page per pass. Run it again on the downloaded file to add a signature to another page.
