- Scenario
- Securing and finalizing a completed PDF form before distributing it to others.
- Observed behavior
- Read-only fields cannot be edited, but they still receive cursor focus and display selection behavior when users click on them.
Because the process of making fields unselectable involves flattening the PDF and permanently removing interactivity, always save a backup copy of your original fillable PDF template.
Flatten the PDF to Convert Fields to Static Text
The most effective way to prevent form field selection is to flatten the document, which permanently merges the field contents with the page background.
Setting a field to 'Read-Only' only restricts data modification. Standard PDF viewers still treat the field as an interactive layer, allowing it to receive focus. Flattening the file resolves this by converting all interactive elements into standard, flat text.
Launch your preferred PDF editor or viewer and open the PDF file containing the read-only form fields.
Press 'Ctrl + P' on Windows or 'Cmd + P' on a Mac to open the print menu.
From the list of available printers, choose a virtual PDF printer such as 'Microsoft Print to PDF' or 'WPS PDF'.
Click the 'Print' button. You will be prompted to save a new file. This newly saved PDF will have all form fields flattened into unselectable, static text.

Frequently Asked Questions
Why does a read-only field still highlight when clicked?
The 'Read-only' status is simply a permission state that prevents text from being typed or modified. The field itself remains an interactive form element, meaning PDF readers still allow it to receive cursor focus, which triggers the highlighting or selection behavior.
Can I lock just one specific field instead of flattening the whole PDF?
You can set individual fields to read-only in the form field properties, but they will remain clickable. To make a single field completely unclickable without flattening the whole document, you would have to delete the interactive field and manually add standard text over the page in its place.
Will flattening the PDF affect hyperlinks or bookmarks?
Yes. Flattening a PDF usually merges all top-level interactive layers onto the base page. This means that active hyperlinks, dropdowns, and form fields may become inactive text. Ensure you only flatten the document when interactive elements are no longer necessary.
