Approaches to Remove Signature from PDF [Newest]

By Roche | Follow twitter | Updated on March 23, 2023 | Deutsch Français
We all know that it is easy to create and add signatures to PDFs, but what if the signee forgets about the digital signature password or signs in the wrong place? It is imperative to know how to erase or delete digital signatures from this PDF in such a situation. Otherwise, one cannot make any edits to the PDF document. Let's go into detail about how to remove signature from PDF.

When we refer to a PDF signature in this post, it actually stands for a digital signature instead of an electronic signature. Reasons? A PDF digital signature enjoys higher security than an electronic signature as it encrypts the document and permanently embeds the information in the PDF document. With a digital signature, no one can randomly edit your PDF.

Once a user attempts to make any changes to the document, the digital signature will be immediately invalidated. Then, without so many PDF signature removers, how do we remove someone else’s signature from PDF? Check out the following PDF signature removers

Desktop PDF Signature Remover (for Windows)

In this section, we will only introduce two methods to remove a digital signature from a PDF. So having access to this PDF document becomes much more manageable.

SwifDoo PDF

SwifDoo PDF is a powerful PDF program that can perform multiple PDF conversion tasks. Users can convert their protected PDFs to Word files, delete the digital signature from the PDF, and save the Word document as a PDF again. Here are the details of removing a digital signature from the PDF:

Step 1: Download and install SwifDoo PDF on your PC, then launch the PDF program;

Step 2: Open a PDF document protected by a digital signature;

Step 3: Click PDF to Word on the tab Convert;

Step 4: Open the converted Word document and remove the signature manually;

Step 5: Save the Word document as a PDF by clicking Export as PDF in the File tab in Microsoft Office.

It is an applicable method to delete your digital signature from the PDF. However, SwifDoo PDF now only allows for adding an electronic signature to your PDF (rather than a digital signature). That’s why users cannot clear the digital signature directly.

If you ever electronically sign a PDF document and want to remove it from the current document, it's a cinch. An electronic signature is actually an image placed on the text layer. Here's how SwifDoo PDF deletes an electronic signature from a PDF.

Step 1: Right-click on the electronic signature in your PDF document;

How to Remove Signature from PDF on Mac

Even with the built-in PDF viewer Preview on Mac devices, removing a digital signature from a PDF appears to be more difficult. Still, we came up with a feasible solution: Adobe Acrobat.

Adobe Acrobat

As Adobe is available both on Windows and Mac, Mac users can expect this comprehensive PDF program to remove their digital signatures from PDFs. Here’s how it works:

Step 1: Open a PDF protected by a digital signature in Preview;

Step 2: Navigate to Preferences, then choose Signatures;

Step 3: Click on Identities & Trusted Certificates, then select More;

Step 4: Select Digital ID Files and choose Detach File.

You can only delete self-signed digital IDs that you created in Acrobat. A digital ID obtained from another provider cannot be deleted from the PDF.

Final Thoughts

Desktop and online PDF signature removers have their strengths. Users can choose either way to remove a signature from a PDF. Personally, however, it is found desktop PDF programs are much more reliable when it comes to digital signature-protected PDFs because all the operations are completed locally without uploading to the server.
