- Scenario
- Distributing a blank fillable PDF form for others to complete with their own data.
- Observed behavior
- Users fill out the form and click Save, which overwrites the original blank template and ruins the master copy.
Ensure you have a backup copy of your original blank PDF template saved in a secure location before applying new security settings or scripts.
Set the PDF File Attribute to Read-Only
The most reliable way to prevent users from overwriting the file on a shared drive is to make the document read-only at the operating system level.
PDF formats do not inherently contain a standard security setting that reliably forces a 'Save As' action across all PDF viewers. By utilizing the operating system's file attributes, you can lock the original file, ensuring that the PDF reader prompts the user to save their changes to a new location.
Navigate to the folder containing your blank PDF template using your computer's file explorer.
Right-click the PDF file and select 'Properties' on Windows, or 'Get Info' on Mac.
In Windows, check the 'Read-only' box under the Attributes section. On Mac, check the 'Locked' box.
Click 'Apply' and 'OK'. Open the file, fill in a field, and try to save. The system will now force you to choose a new file name and location.
Add Document-Level JavaScript to Trigger 'Save As'
Embed a JavaScript command within the PDF that automatically prompts the 'Save As' dialog box when the user attempts to save or print the document.

Frequently Asked Questions
Is there a built-in PDF setting that disables the 'Save' button?
No, standard PDF specifications do not include a security setting that disables the 'Save' button universally while allowing a user to fill out a form. You must rely on external file attributes like 'Read-only' or embedded JavaScript to influence saving behavior.
Will making the PDF Read-Only prevent users from filling out the form?
No. When a PDF is set to Read-Only at the file system level, users can still open the document, click into the form fields, and type in their data. The restriction only takes effect when they attempt to save, at which point they are forced to save a new copy.
Why does my embedded JavaScript Save As prompt not work for some users?
JavaScript relies entirely on the capabilities and security settings of the specific PDF viewer the end-user is utilizing. Many built-in web browser PDF viewers (like Chrome or Edge) and mobile PDF apps do not execute document-level JavaScript, causing the script to be bypassed.
