Observed behavior

Solution 1Recommended

Verify Original Form Interactivity and Save as Copy

Test the form before signing to isolate whether the issue stems from the document's configuration or the Adobe signature flattening process.

Some PDF viewers or basic signature tools automatically flatten the entire document when saving a signature. This converts interactive buttons into static images.

By testing the buttons beforehand and using the 'Save As' function, you can identify the exact point where the form loses its interactivity.

1
Open the original file

Open the original, unsigned PDF file in Adobe Acrobat.

2
Test the buttons

Click on the 'Print', 'Clear', or 'Submit' buttons on the form to confirm they function correctly before any signature is applied.

3
Apply signature

Use the Fill and Sign tool to add your signature to the designated field.

4
Save as a copy

Go to File > Save As (instead of Save) and create a new copy. Re-test the buttons in this newly saved document.

Verify Original Form Interactivity and Save as Copy
Identify Form Creator: If the buttons do not work even before signing, the issue lies in how the PDF was originally created. Check File > Properties > Description to see the application used to create the PDF.

Frequently Asked Questions

Why does adding a signature flatten my PDF form?

Certain PDF applications automatically flatten the document when saving a signature using basic tools. This is done to prevent further modifications to the signed data, but it inadvertently turns interactive elements like buttons into static images.

Does locking a document after signing disable form buttons?

Yes. If you or the document creator selects the 'Lock document after signing' option during the digital signature process, all form fields, drop-downs, and interactive buttons will become read-only and unresponsive.

Can I recover the functionality of my form buttons after saving?

If the document was flattened and saved over the original file without a backup, the interactive buttons cannot be easily restored. It is best practice to always save the signed document as a separate copy.
