How to Fix a Completed PDF Form That Cannot Be Filled by Another Person
Question details
The user needs to understand why a returned employee review PDF form is locked and how to allow the next person to fill out their section.

- Product
- Device & OS
- not provided
- 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.
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.
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.
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.
Ask the previous person to open the original blank interactive form and fill out their section again.
Instruct them to strictly use the 'Save' or 'Save As' function in their PDF reader, rather than selecting 'Print to PDF' or 'Export'.
Receive the newly saved interactive PDF file and forward it to the next person in the review chain.

Check for Digital Signatures Locking the Form
Digital signatures often lock a document to prevent tampering after signing, making the remaining fields inaccessible.

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.
