How it works
Draw, type, or upload your signature, then click on the PDF page preview to place it. The signature is embedded as an image at the coordinates you picked, on the page you selected. Everything happens in your browser.
Common use cases
- Signing a contract received by email without printing, scanning, and re-attaching.
- Adding a signature to an administrative form (URSSAF, CERFA, bank paperwork) before returning it.
- Signing a delivery slip or invoice from a phone or tablet before sending it back.
Privacy
This tool runs entirely in your browser. Your PDF is never uploaded to our servers — the file stays on your device from start to finish.
FAQ
Is this signature legally binding?
It's an image signature — the same legal weight as a hand-signed page you scan. For qualified electronic signature (eIDAS QES, DocuSign-level), a certified provider is required. For most everyday paperwork, an image signature is what's expected.
Should I flatten the PDF after signing?
Yes if you want the signature to be non-removable. After signing, run the file through Flatten PDF — the signature will bake into the page content and can't be edited or removed by the recipient.
