Edit a signed PDF without Adobe
Once a PDF is signed, most editors refuse to touch it — you'd invalidate the signature. But sometimes you need to add a missing field, fix a typo or update a date before the signature gets countersigned.
Why this works
Our edit flow flattens the existing signature appearance to an image, lets you edit, and lets you re-sign yourself or send to the next signatory. No Adobe Acrobat license required.
How it works
-
1Open the edit toolClick the orange button above to launch the editor with signed-PDF mode on.
-
2Upload the signed PDFDrop the file in. The existing signature stays visible as an image.
-
3Make your editsAdd text, fill fields, fix typos. The signature remains as a graphic, not a cryptographic seal.
-
4Re-sign and downloadApply your own signature with the Sign tool, or save unsigned for the next signer.

Common questions
Does this break legal validity?
It invalidates the cryptographic signature. The visible signature image remains. For legal authenticity, get a fresh signature on the edited file.
Can I add another signature on top?
Yes — use the Sign tool after editing to apply your own signature. Multiple signatories can sign in sequence.
