How to sign a PDF

  1. Upload the PDF that needs signing.
  2. Create a signature — draw one with a mouse, trackpad, or finger on a touchscreen; type your name in a handwriting-style font; or upload an existing signature image — a plain phone photo of your signature on paper works, the paper background is removed automatically.
  3. Click on the PDF page to place the signature, drag to reposition, resize with the corner handle, navigate to other pages if needed. Click Save Signed PDF to download.

Drawn, typed, or uploaded — which is right?

Drawn gives the most authentic look on a touchscreen — stylus or finger both work. Typed is the fastest for routine acknowledgments where a stylised cursive is acceptable. Uploaded is best when you have a clean signature image on file already; place it once and every subsequent document feels like a real wet signature. None of the three are cryptographically signed — for a digitally verifiable signature, use the PDF signature certificate flow in Adobe Acrobat or a dedicated e-sign service.

Frequently asked

Is this signature legally binding?

In most jurisdictions, an image-style signature placed on a PDF has the same legal weight as wet ink — it is an electronic signature under laws like the Indian IT Act, US ESIGN, and eIDAS in the EU. For contracts that specifically require a qualified digital signature (tax filings, some government forms), you need a crypto-signed PDF — this tool does not produce that.

Can I add a date or initials too?

Combine with the Edit PDF tool to add typed initials, a date, or a printed name next to the signature.

Will a recipient be able to remove my signature?

Yes — any image added to a PDF page is not permanently bonded. After signing, run the result through Flatten PDF to bake the signature into the page image. That makes it cosmetically permanent.

Can I upload a phone photo of my signature on paper?

Yes — upload it straight from the camera roll. AllPDF removes the paper for you: it evens out the lighting in the photo, keeps the ink (including its colour) and makes everything else transparent, so the signature sits cleanly over the text underneath. Signature images that already have a transparent background are used exactly as-is.

Privacy: Your signature, the PDF, and the signed output all stay inside your browser tab. pdf-lib writes the signature image onto the page locally — nothing is uploaded.
