How to Restore the Missing Fill & Sign Pen Icon in Adobe Acrobat
Question details
The user needs to find and restore the pen icon required for creating and placing signatures in Acrobat.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Attempting to sign a PDF document using the Fill & Sign tool.
- Observed behavior
- The signature pen icon has disappeared from the Acrobat interface, preventing the user from signing the PDF despite the Fill & Sign tool being active.
Verify that your PDF document does not have security restrictions preventing signatures, and ensure you are logged into your active Adobe account.
Locate Signature Controls within the Fill & Sign Pane
Often, the signature pen icon isn't actually missing but has been relocated within the Fill & Sign tool's specific interface pane due to recent UI updates.
In updated versions of Adobe Acrobat, the signature control might be housed directly within the Fill & Sign secondary menu rather than the top global toolbar.
Open your PDF in Acrobat and select 'Fill & Sign' from the main Tools menu or the right-side tools pane.
Look for the 'Sign Yourself' or 'Add Signature' control directly within the Fill & Sign panel bar that appears.

Sign Out, Update, and Reset Preferences
If the icon is genuinely missing from all toolbars, an account sync error, outdated software version, or corrupted preferences might be the root cause.

Frequently Asked Questions
Why is the Fill & Sign option greyed out in Acrobat?
The Fill & Sign option is usually greyed out when the PDF has security settings applied by the author that restrict filling form fields or adding signatures. You will need the document password to remove these restrictions.
Can I customize the toolbar to bring the pen icon back?
Yes, you can manually customize your quick tools. Right-click an empty space on the top toolbar, select 'Customize Quick Tools', locate the signature options under the Fill & Sign category, and add them back to your top menu.
Does WPS Office offer a free way to sign PDFs?
Yes, WPS Office includes a built-in PDF editor that allows you to freely create, place, and manage digital and drawn signatures without requiring a premium subscription.
