Scenario
Multiple people need to fill out different sections of an employee review PDF form sequentially.
Observed behavior
After the first person returns the filled form, the next person is unable to enter information into the remaining fillable fields.
Before you start

Ensure you have access to the original, blank fillable PDF file as a backup, and verify that the first person did not apply any digital signatures which automatically lock the document.

Solution 1Recommended

Ensure the Form Was Saved, Not Printed to PDF

Printing a form to PDF flattens the fields, making them uneditable. The document must be saved normally to preserve interactive fields.

When an interactive PDF is processed incorrectly by a user, it can inadvertently convert fillable fields into static text. This is a common workflow issue rather than a file corruption problem.

1
Inspect the Document

Open the returned PDF form and click on the areas that should be fillable fields. If there is no cursor or highlight indicating a form field, the document has been flattened.

2
Instruct the Previous User

Ask the previous person to open the original blank interactive form and fill out their section again.

3
Save Correctly

Instruct them to strictly use the 'Save' or 'Save As' function in their PDF reader, rather than selecting 'Print to PDF' or 'Export'.

4
Distribute the File

Receive the newly saved interactive PDF file and forward it to the next person in the review chain.

Ensure the Form Was Saved, Not Printed to PDF
Flattened PDFs: Once a PDF is flattened (such as by printing to PDF), the form fields become regular text and cannot be easily reactivated without recreating the fields manually.

Frequently Asked Questions

Why did my fillable PDF become flat and uneditable?

This usually happens if the document was 'Printed to PDF' instead of being saved. Printing to PDF converts interactive form fields into static text, permanently locking them.

Can I unlock a PDF form after it has been digitally signed?

Generally, no. A digital signature is designed to lock the document and prevent further changes to ensure data integrity. You will need to start over with a blank copy of the form.

How can I prevent users from locking the PDF form?

Provide clear instructions to use the 'Save' button rather than 'Print to PDF' or 'Export'. Additionally, advise them to only apply digital signatures if they are the final person in the review process.

Can I add text to a PDF that has already been flattened?

Yes, using a PDF editor like WPS Office, you can use the 'Add Text' tool to type over a flattened PDF, though the original form fields will no longer be interactive.
