Remove Signature
Remove digital signatures and certificate fields from your PDF.
Remove digital signatures from PDF documents when you need to edit a signed document or clear signatures before re-signing. Processes entirely in your browser without uploading files.
Why Removing Digital Signatures Requires Careful Handling
Digital signatures in PDF are designed to be difficult to remove without invalidating the document — that's the point of tamper-evidence. When you remove a signature, you're essentially making a new, unsigned version of the document. The signature and its embedded certificate data are stripped from the PDF's signature fields, and any signature appearance graphics are removed from the page.
In PDF's incremental update model, signatures are applied by appending to the document rather than modifying it in place. A proper signature removal involves creating a fresh, flattened PDF that doesn't carry the signed revision's byte-range integrity data. The resulting document is a clean, unsigned PDF that can be freely edited and re-signed.
Important: if a PDF was signed with 'certify' rather than 'approval' permissions, the original signer restricted future modifications. Removing a certification signature allows unrestricted editing but destroys the evidentiary value of the signature — make sure you have the authority and legitimate reason to do so before proceeding.
Clear expired or invalid signatures
Remove signatures with expired certificates or from CAs that are no longer trusted to prepare the document for fresh signing.
Edit a previously signed document
Strip signatures to enable edits, then re-sign after changes are made — useful when content corrections are needed.
Remove test signatures before production
Clean up test digital signatures applied during development or QA review before a document enters its production signing workflow.
- 1
Upload the signed PDF
Select the PDF containing digital signatures you want to remove. The tool will detect and list all signature fields in the document.
- 2
Select signatures to remove
Choose which signatures to remove — all of them, or specific ones by signer name or signature field name if the document contains multiple signatures.
- 3
Remove and download
Click Remove Signatures and download the resulting unsigned PDF ready for editing or re-signing.
Selective signature removal
Remove specific signatures by field name while preserving others — useful in multi-signer documents where only some signatures need to be cleared.
Clean output without signature artifacts
Removes both the cryptographic signature data and any visible signature appearance graphics, leaving a clean unsigned document.
Client-side only
Signature removal runs in your browser — no document content is sent to external servers.
