Offer letters, rental agreements, school forms and invoices all come as PDFs that need a signature. Printing, signing and scanning takes ten minutes and a printer; this takes one, and works the same on a phone.

Your signature is turned into a transparent image in your browser and placed onto the pages you choose with pdf-lib. The rest of the PDF is left exactly as it was, and neither the document nor your signature is uploaded anywhere, which matters for something as personal as a signature.

Uploading a photo of your real signature gives the most natural result: sign on plain white paper, take a well-lit photo, and Remove the paper background cuts it out cleanly. Same spot on all pages copies a signature to every page, handy for initialling each page of an agreement.

Questions

Is my document or signature uploaded?

No. Both stay in your browser tab. Nothing is sent to a server or stored.

Is this a legally valid signature?

It's a visual electronic signature, the same as signing a printout and scanning it, which is accepted for most everyday documents. It isn't a certificate-based digital signature (like DSC or Aadhaar eSign), which some government filings require.

Can I sign more than one page?

Yes. Move between pages with the arrows and click to place your signature on each, or use Same spot on all pages.

Can I use a photo of my handwritten signature?

Yes. Choose Upload photo. On white paper with good light, the background is removed automatically.

Can I sign a password-protected PDF?

Not yet. Remove the password first; the tool tells you if a file is protected.
