Question details
The user needs to lock specific form fields in a fillable PDF to prevent recipients from changing pre-filled information before signing the document.

- Device & OS
- not provided
- Scenario
- Preparing and sending a pre-filled PDF document to external recipients for an electronic signature.
- Observed behavior
- The recipient must be able to apply their signature, while the previously entered data in the text fields remains locked and uneditable.
Ensure you have completely and accurately filled out all necessary information in the PDF form fields before locking them, as you will not be able to type in them once read-only mode is activated.
Make Fields Read-Only via Form Properties
Use the form preparation tools to manually set specific filled fields to read-only prior to initiating the signature request.
This method is ideal for completely securing specific data fields in a form template before you even start the sharing or sending process. By adjusting the individual properties of each field, you guarantee that only the designated signature blocks remain interactive.
Open your fillable form in your PDF desktop application (such as Adobe Acrobat) and select the 'Prepare Form' tool from the right-hand pane or the Tools menu.
Right-click the specific form field you want to lock and select 'Properties' from the context menu.
In the Properties dialog box, locate and check the 'Read Only' option. Repeat this process for all the data fields you wish to restrict.
Select the 'Request Signatures' tool, add a new signature field, assign it to the intended signer, and send the document.
Set Fields to Read-Only During Signature Request
Make form fields read-only on the fly while actively setting up the signature request.

Frequently Asked Questions
Can I unlock read-only form fields later?
Yes, as the document creator, you can open the file in the 'Prepare Form' mode again, right-click the locked field, open its Properties, and uncheck the 'Read Only' box to make it editable.
Does making a field read-only affect the signature field?
No, as long as you only apply the read-only property to the text or data fields. You must ensure the actual signature field remains editable so the recipient can successfully sign.
Why do my read-only fields appear grayed out?
Many PDF viewers highlight read-only or locked fields with a gray background by default. This is a visual indicator to users that the information within those specific boxes cannot be modified.
Is it possible to make the whole PDF read-only instead of field by field?
Yes. Instead of using form properties, you can use the 'Protect' or 'Restrict Editing' feature to apply a permissions password to the entire document, allowing users only to fill in signatures without changing the underlying text.
