Question details
The user wants to convert an interactive, completed PDF form into a static document where the inputted data remains visible, but the form fields themselves are locked or removed to prevent further editing.

- Scenario
- Preparing a completed PDF form for final submission, archiving, or sharing to ensure the data cannot be altered.
- Observed behavior
- The PDF file currently contains interactive fillable fields that need to be safely merged into the document's base layer without losing the user's inputted text.
Verify that all required form fields have been filled out completely, and save a backup copy of your original interactive PDF file just in case you need to correct typos later.
Lock All Form Fields Using a Digital Signature
Add and configure a digital signature field to automatically lock all other form fields once the document is signed.
Digitally signing a document is one of the most reliable ways to finalize a PDF. By editing the signature field's properties before signing, you can instruct the software to lock every field in the document, effectively flattening the form while authenticating it.
Open your completed PDF form in your PDF editor. If it does not already have a signature field, add a new one from the form tools menu.
Right-click on the newly added signature field and select 'Properties' from the context menu.
Navigate to the 'Signed' tab within the properties window. Check the option that says 'Lock all fields' or 'Mark as read-only' upon signing.
Close the properties window and save the file. Finally, click on the signature field to digitally sign the document, and save this finalized version under a new file name.

Frequently Asked Questions
Can I edit a PDF again after it has been flattened?
Once a PDF is flattened, the interactive form fields are permanently converted into standard text. You will no longer be able to use the form functionality. However, you can still edit the text if you use a premium PDF editor's text editing feature.
Why is it important to flatten a fillable PDF before sending it?
Flattening a PDF locks the entered data in place, preventing the recipient from accidentally or intentionally modifying your responses. It also ensures the document displays correctly on devices that might not fully support interactive PDF forms.
What happens to dropdown menus when a PDF is flattened?
When the flattening process occurs, only the currently selected and visible value from the dropdown menu is retained as static text. All other unselected options in the menu list are permanently removed from the document.
Does flattening a PDF reduce its overall file size?
Yes, in many cases, flattening a PDF can reduce the file size by removing the interactive layer, scripts, and embedded form elements, leaving only the consolidated text and images.
