If I extract just the signature page from a digitally signed contract, is the signature still valid?
No. A digital signature is tied to the complete original file, so a page extracted into a new PDF carries no signature that can be verified. If the recipient needs to check the signature, send the original contract; extract the page only when a copy for reading is enough.
A signature you can see versus one that can be verified
Two kinds of signature get confused all the time. The first is an image of a signature or a stamp placed on the page. It is part of the page content, so it travels with the page and looks the same after extraction. The second is a certificate-based digital signature added by signing software or an e-signature service. It fingerprints the bytes of the whole file, and your PDF reader uses it to confirm the file has not changed since signing, showing the signer and the signature status.
When you extract a page, the tool builds a brand-new file that holds only the pages you chose. The page looks the same, and the drawn signature may be visible on it, but the new file is not the file that was signed, so it has no valid digital signature to verify. The tool also shows a warning when you open a file in which it detects a digital signature.
When the extracted page is enough
- You want a partner or accountant to read the pricing or terms page, nothing more.
- Someone wants an informal sign that the contract was signed and is happy with a copy of the page, without formal verification.
- You keep a short internal copy for quick reference while the original stays safely filed.
When to send the full original
- You are submitting the contract to an authority, a bank or a platform that verifies signatures.
- The other party may rely on the contract in a dispute or a claim.
- You do not know exactly what the recipient will do with it. Then the original is the safe choice.
This is not legal advice. If signature validity matters in a particular situation, ask whoever receives the contract what they accept.
If you decide to extract a page for reading
- Open Split PDF and choose the contract. If the digital signature warning appears, remember the output is a reading copy.
- Choose “Extract to one PDF” and type the signature page's position in the file, for example 7 for a 7-page contract.
- Press “Split and download” to get contract-pages-7.pdf, if the original is named contract.pdf.
- When you send it, tell the recipient plainly that it is a copy for reference and that the signed original is available on request.
Common questions
Does extracting damage the signature on my original?
No. The tool only reads the original and never modifies it, so the signed contract on your device stays valid as it was.
Will the signature appear on the extracted page?
If it is drawn on the page as an image or stamp, yes. Seeing it does not mean the digital signature can be verified.
