Where to find and delete a signature in Adobe
To delete a signature in Adobe Acrobat, open the PDF with the signature you want to remove. Click the Tools menu at the top, then select Protect and look for Manage Signatures or Signature Panel depending on your version. A panel will appear on the right side showing all signatures in the document. Right-click on the signature you want to remove and select Clear Signature or Delete.
If you are using Adobe Reader (the free version), you cannot delete signatures — you can only view them. Signature removal requires Adobe Acrobat Pro or Acrobat Standard. If you only have Reader, you will need to use the full Acrobat version or ask someone with editing access to remove it for you.
In Adobe Sign (the online signing service), you cannot delete a signature after it has been placed on a document that has already been sent or completed. You would need to start a new signing request instead.
Key Takeaways
- Deleting a signature in Adobe Acrobat requires the paid Pro or Standard version, not the free Reader.
- Open the Tools menu, select Protect, then Manage Signatures to see all signatures in the document.
- Right-click the signature you want to remove and choose Clear Signature or Delete from the menu.
- Once a document is signed and sent through Adobe Sign, you cannot delete the signature — you must create a new signing request instead.
The difference between clearing a signature and deleting a document
Clearing a signature removes the signature mark itself from the PDF, but the document remains. The file stays on your computer or in your cloud storage. This is useful when you need to remove someone's signature but keep the document for other reasons — like removing a test signature before sending the final version, or taking off an old approval when a document needs to be re-signed.
Deleting the entire document removes the file itself. If you want to get rid of the whole PDF, you would delete it from your file system or cloud storage the same way you delete any other file — by moving it to trash or using your operating system's delete function.
How to remove your own signature from a document you created
If you added your own signature to a document and want to remove it, the process is the same: open the document in Acrobat Pro, go to Tools > Protect > Manage Signatures, find your signature in the list, and click Clear Signature. The document will show that a signature was removed, but the signature itself will no longer be visible.
If the document has been sent to others through Adobe Sign, removing your signature from your copy does not affect the versions other people have received. They will still see your signature on their copies. To prevent your signature from appearing on documents going forward, you would need to delete your signature from your Adobe Sign account settings, not from individual documents.
What happens when you clear a signature
When you clear a signature from a PDF, Adobe leaves a record that a signature was removed. The document will show a blank space where the signature was, and the signature panel will indicate that the signature has been cleared. This creates an audit trail — anyone opening the document can see that a signature existed and was later removed.
The document itself does not revert to an unsigned state in the legal sense. If the signature was part of a formal signing process, removing it may affect the document's validity depending on your industry or use case. For example, removing a signature from a contract might make it unenforceable, or removing a signature from a medical form might require re-signing. Check your organization's policies before clearing signatures from important documents.
Removing signatures from documents in Adobe Reader on mobile
Adobe Reader on phones and tablets (iOS and Android) does not have the ability to delete signatures. You can view signatures and verify them, but you cannot remove them. To delete a signature, you must use Adobe Acrobat Pro on a desktop or laptop computer.
If you need to remove a signature from a document while on the go, you can read the document to your computer, open it in Acrobat Pro, remove the signature, and then re-upload or save it. Some organizations also allow you to request a new unsigned version of a document from the person who signed it.
Removing multiple signatures at once
If a document has been signed by multiple people and you need to remove all the signatures, open the Manage Signatures panel and clear each signature one at a time. Adobe does not have a "clear all signatures" button — you must select and remove them individually. This is intentional, to prevent accidental removal of important signatures.
If you are removing signatures from many documents, the fastest approach is to open each document, access the Manage Signatures panel, and work through them in order. Keeping a list of which documents you have modified can help you track your progress and avoid mistakes.
Why you might not be able to delete a signature
If you are trying to delete a signature and the option is grayed out or unavailable, the document may be locked or protected. Some PDFs have restrictions that prevent editing, including signature removal. To check if a document is locked, go to Tools > Protect > Manage Security and look for any restrictions listed.
If the document is password-protected or has editing restrictions, you will need the password to unlock it before you can remove signatures. If you do not have the password, contact the person who created or locked the document. You may also not have permission to edit the document if it is stored in a shared folder or cloud service with restricted access.
Frequently Asked Questions
Can I delete a signature from a PDF without Adobe Acrobat Pro?
No. Adobe Reader does not have the tools to remove signatures. You need Acrobat Pro or Acrobat Standard. Some third-party PDF editors claim to remove signatures, but they may not preserve the document's integrity or create a proper audit trail of the removal.
If I remove a signature, can the other person tell it was deleted?
Yes. Adobe keeps a record in the Manage Signatures panel showing that a signature was cleared. Anyone with access to the document can see that a signature existed and was removed, along with the date and time of removal. The signature itself will not be visible, but the history remains.
What if the document is locked and I cannot remove the signature?
The document likely has security restrictions. Go to Tools > Protect > Manage Security to see what restrictions are in place. If it is password-protected, you will need the password to unlock it. Contact whoever created or locked the document if you do not have the password.
Can I undo a signature removal?
No. Once you clear a signature and save the document, the removal is permanent. Use Ctrl+Z (or Command+Z on Mac) when ready after clearing to undo, but only before you close or save the file. After saving, the signature cannot be restored — you would need to ask the signer to sign again.
Does removing a signature from my copy affect other people's copies?
No. If a document has been sent to multiple people through email or Adobe Sign, removing the signature from your copy does not change what others see. Each person has their own copy. To remove a signature from all copies, each person would need to remove it from their own version.
