Question details
The user wants to hide the blue fillable-field highlighting for specific completed fields in a PDF form while leaving the remaining fields highlighted and editable for clients.

- not provided
- Scenario
- Staff members are entering partial information into a PDF form (like name and address) and need to save it without the blue highlights on their filled sections before passing it to a client.
- Observed behavior
- Fillable fields display a blue background highlight by default. This highlighting is a global setting and cannot be natively disabled for individual fields while keeping others highlighted.
Before modifying your form properties or adding scripts, ensure you have saved a backup copy of the original PDF. You will need a PDF editor that supports form creation and JavaScript execution.
Use JavaScript to Make Completed Fields Read-Only
Since highlighting applies universally to all active fillable fields, converting the completed fields to 'read-only' will automatically remove their individual blue backgrounds.
PDF editors toggle field highlighting for the entire document, meaning you cannot natively turn it off for just a selected few fields. However, read-only fields do not display this interactive highlighting. By adding a simple JavaScript toggle (like a button or checkbox), you can lock the completed fields and remove their highlighting instantly.
Open your PDF form in your preferred PDF editor and navigate to the 'Prepare Form' or 'Edit Form' tool to access field properties.
Insert a new Button or Checkbox onto the form. This is what the staff member will click once they finish entering their specific section.
Right-click the newly created button or checkbox and select 'Properties' from the context menu.
Navigate to the 'Actions' tab. Select 'Run a JavaScript' from the action dropdown menu and click the 'Add' button.
Type a script that sets the staff fields to read-only. For example: this.getField("StaffName").readonly = true; Replace 'StaffName' with the exact name of your text field. Click 'OK' to save.
Exit form editing mode. Fill in the staff fields, then click your new button. The fields will lock, and the blue highlight will disappear, leaving the client fields ready for input.

Frequently Asked Questions
Can I turn off field highlighting for the entire PDF document?
Yes. In most PDF readers, you can disable the global field highlighting by toggling the 'Highlight Existing Fields' button (typically found at the top right of the document) or by adjusting your application's viewing preferences.
Does making a field read-only prevent clients from changing the data?
Yes. Once a field is set to read-only, its contents are locked and cannot be edited by the user. This safely preserves the staff's input while the client fills out the remainder of the form.
Will the blue highlight show up when the PDF is printed?
No. The blue background highlighting is strictly an interactive visual aid for digital viewing and data entry. It does not appear on the physical paper when the document is printed out.
How do I undo the read-only status if I made a mistake?
If you are using a checkbox with JavaScript, you can write an 'if/else' script that toggles the read-only status back to false when the box is unchecked. Otherwise, you must return to the form editor mode and manually uncheck the 'Read Only' property in the specific field's settings.
