PDF
Device & OS
not provided
Scenario
Distributing a blank fillable PDF form template to multiple users or clients who need to fill it out and return a copy.
Observed behavior
Users need to fill out the form and save a completed copy without altering or overwriting the original blank template on the system.
Before you start

Ensure that your PDF form fields are correctly formatted and tested. Always keep a secure, unshared backup of the original blank PDF template in a private folder before distributing it.

Solution 1Recommended

Set the PDF File and Folder to Read-Only

Restrict the original file from being overwritten by modifying the file and folder properties at the system level, forcing users to utilize the Save As function.

By applying a read-only attribute to the file and the network folder it resides in, the PDF reader will prevent the user from saving changes directly to the original document.

1
Locate the PDF Form

Navigate to the folder containing your blank PDF form using your computer's file explorer.

2
Open File Properties

Right-click on the PDF file and select 'Properties' from the context menu.

3
Enable Read-Only Attribute

Under the General tab, check the 'Read-only' box at the bottom and click 'Apply', then 'OK'.

4
Apply to Folder (Optional but Recommended)

If the file is on a shared network drive, right-click the folder containing the file, go to 'Properties', and set the folder permissions to restrict write access for general users.

Set the PDF File and Folder to Read-Only
Local Machine Limitations: If users copy or download the file to their own personal computers, they will gain administrative control over the file and can manually remove the read-only attribute.

Frequently Asked Questions

Can I lock a blank PDF using a password so it cannot be saved over?

Password protection typically restricts editing the content or filling the form fields altogether. If you want users to fill the form but prevent them from overwriting the original file, using file-level read-only attributes or specific network permission settings is more effective.

What happens if a user tries to click 'Save' on a read-only PDF form?

Their PDF reader will automatically intercept the action and prompt them with a 'Save As' dialog box. This forces them to create a new file with a different name or to save it in a completely different folder location.

Is it possible to completely prevent users from removing the read-only attribute?

If a user downloads the file to their own computer, they gain local administrative control and can right-click the file to turn off the read-only setting. For strict control, you must host the file on a secure shared network drive or DMS where they only have 'Read' permissions.

Will setting the network folder to read-only protect the original PDF?

Yes. If the network folder is set to read-only for those specific users, they cannot save the filled-out copy back into the same directory. This successfully protects the original template from being accidentally overwritten on the server.
