- Device & OS
- not provided
- Scenario
- Reusing a fillable PDF form that contains reset and email buttons, but retaining an old signature after a form reset.
- Observed behavior
- When the reset button is clicked, standard fields are cleared, but the digital signature field retains the previous customer's signature.
Verify that you have the necessary permissions or document passwords, as clearing a digital signature often requires authorization from the original signer or the document owner.
Manually Clear the Signature via Right-Click
Use the context menu to manually remove the digital signature from the specific field.
Because digital signatures are designed to lock document integrity, standard form reset buttons usually bypass them. Manually clearing the field is the most direct approach if you have the correct permissions.
Open your fillable PDF form and scroll to the signature field that contains the old digital signature.
Right-click directly on the signature field and select 'Clear Signature' from the drop-down menu.

Configure the Reset Button to Exclude Signatures
Adjust the properties of the reset button so it handles standard text fields properly without causing conflicts with secure signature fields.
Manage Fillable Forms and Signatures with WPS Office
WPS Office provides a highly compatible PDF editor that makes it easy to handle fillable forms, securely manage digital signatures, and edit document properties without the hassle.
- 1. Open your form: Launch WPS Office and open the fillable PDF document.
- 2. Find the signature: Navigate to the signature field containing the old signature.
- 3. Clear signature: Right-click the signature field and select the option to clear it.
- 4. Save changes: Save the document to finalize the removal and prepare it for the next user.

Frequently Asked Questions
Why doesn't the reset button clear the digital signature automatically?
Digital signatures are protected by security protocols to ensure document integrity and prevent tampering. For this reason, bulk reset actions typically bypass signature fields, requiring them to be cleared manually by an authorized user.
Can I remove a signature if I am not the original signer?
In most cases, you cannot. Digital security settings typically restrict signature removal to the individual who originally applied the signature or an administrator with the appropriate document password.
How can I reuse a fillable form without dealing with old signatures?
The best practice is to save a blank, unsigned template of your form. When a user fills it out and signs it, use the 'Save As' function to create a new file, keeping your original template clear of any signatures.
