Unlock a signed PDF for editing
Make a signed document editable again, without uploading it.
Once a PDF is signed, most readers refuse to let you change it. To fix a typo or update a figure, you need to remove the signature first. This tool does that in your browser, so the document is never uploaded.
How to unlock a signed PDF for editing
- 1
Add your PDF
Drop in the signed, locked document.
- 2
Remove the signature
The signature is cleared on your device, unlocking edits.
- 3
Edit and re-sign
Make your changes, then sign the corrected version.
Why unlock on your device
Unlocking a signed document in the browser keeps it local, so a file you need to correct is never uploaded to a server.
