How to Flatten a PDF While Keeping Signature Fields Open
Question details
The user wants to lock or flatten completed form fields in a PDF document while ensuring that the signature and initials fields remain active for clients to sign.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Preparing a PDF contract or form for client delivery where existing data must remain unaltered, but the document still requires a digital signature.
- Observed behavior
- The user needs a method to selectively lock specific fields without disabling the entire document's interactive signature capabilities.
Ensure you save a backup copy of your original fillable PDF form before modifying field properties, as reversing locked or flattened fields can be difficult once the document is saved.
Use Signature Field Properties to Lock Specific Fields
Configure a preliminary signature field's properties to automatically lock all other form fields upon signing, leaving the client's signature field fully active.
A standard 'Flatten' command merges all interactive elements into the background layer, which breaks signature functionality. Instead of flattening the entire document, you can use the 'Signed' properties of an author signature field to selectively lock the text fields while keeping the client's signature fields open.
Open your PDF document in Adobe Acrobat, go to the Tools menu, and select 'Prepare Form' to view all interactive fields.
Insert a new digital signature field that you (the document preparer) will sign before sending the document to the client.
Right-click your new author signature field and select 'Properties'. Navigate to the 'Signed' tab.
Check the box that says 'Mark as read-only'. From the dropdown menu, select 'All fields except these'. Click 'Pick' and select the client's signature and initials fields from the list to exclude them from being locked.
Close the properties window. Sign your author signature field. Once signed, all completed text fields will become read-only (effectively flattened), while the client's signature fields will remain open and ready for use.

Frequently Asked Questions
Does standard flattening remove PDF signature fields?
Yes, standard flattening merges all interactive elements, including text boxes, checkboxes, and signature fields, into the main document layer. To keep signature fields open, you must selectively lock fields instead of using a global flatten command.
How can I flatten only specific pages of a PDF?
You can extract the specific pages you want to flatten, print those pages to PDF (which flattens their contents), and then replace the original pages in your interactive document using the 'Organize Pages' tool in a PDF editor.
Why is my client unable to sign the PDF after I locked it?
If you selected 'Lock All Fields' in your signature properties, the client's signature field was also locked. Ensure you use the 'All fields except these' option to specifically exclude the client's signature and initials fields from the lock.
Can I unlock a flattened PDF later?
Once a PDF is fully flattened and saved, the interactive form fields are permanently converted to regular text and images. They cannot be easily unlocked, which is why keeping an unflattened master copy of your form is crucial.
