Question details
Users are unable to modify text, annotations, or check marks added to a PDF document after using the Acrobat Fill and Sign tool, saving the file, and reopening it.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Filling out and saving a non-interactive PDF form using the Fill and Sign tool, then attempting to update the information later.
- Observed behavior
- The added text and signatures become permanently flattened into the background of the PDF document upon saving, preventing any further edits or deletions.
Before making permanent additions to a non-fillable PDF form, always save a copy of the blank original file so you can start over if your completed entries become locked.
Use Native Interactive Form Fields
The Fill & Sign tool is designed for flat additions that lock upon saving. Utilizing native interactive PDF form fields ensures your entered data remains editable.
The Acrobat Fill and Sign feature is intended as a quick way to add flat text and signatures to non-interactive PDFs. When you save and reopen the document, these elements are intentionally flattened into the base layer of the PDF for security and document integrity purposes.
To avoid this limitation, you should utilize native form fields whenever the PDF was created as an interactive, fillable form.
Open your PDF and look for highlighted interactive fields. Do not open the 'Fill & Sign' tool from the side panel.
Click directly into the highlighted text boxes, checkboxes, or radio buttons to input your information natively.
Go to 'File' > 'Save' to save the document. Because you used standard interactive form fields, your text will remain fully editable the next time you open the file.

Use Standard Commenting Tools for Non-Fillable PDFs
If the PDF lacks interactive form fields, use standard text boxes and commenting tools to overlay information that you can easily edit at a later time.
Easily Fill and Edit PDF Forms with WPS PDF
WPS Office includes a powerful built-in PDF editor that allows you to add text, insert interactive text boxes, and manage documents without permanently locking standard text entries. It offers a flexible and reliable way to handle both fillable and non-fillable forms.
- 1. Open your PDF in WPS Office: Launch the WPS Office application and open your non-fillable or interactive PDF document.
- 2. Use the Comment or Edit tabs: To add editable text, navigate to the 'Comment' tab and select 'Text Box', or go to the 'Edit' tab and click 'Edit Text'.
- 3. Type your information natively: Click on the blank area of the form and type your details. You can easily adjust the font, size, and color using the right-side properties panel.
- 4. Save and edit indefinitely: Save your document. Because WPS PDF manages your text additions as distinct editable layers, you can click and modify the text instantly upon reopening.

Frequently Asked Questions
Can I unlock a PDF that was flattened by the Fill and Sign tool?
Once a document has been saved and closed after using Fill and Sign, the text and signatures are usually permanently flattened into the background image for security. You cannot typically unlock or separate them unless you have saved a backup copy prior to signing.
Why does Adobe specifically flatten Fill and Sign entries?
These entries are flattened to prevent unauthorized modifications to signatures and form data after the document is finalized, ensuring a basic level of document security and legal integrity.
How do I create fillable form fields that stay editable?
You can use the 'Prepare Form' tool in a premium PDF editor to add interactive text fields, checkboxes, and radio buttons. Data entered into these native interactive fields remains editable even after the file is saved and reopened.
Will standard text comments show up when I print the PDF?
Yes, standard text boxes and comments will print perfectly as long as you select 'Document and Markups' in the printing properties dialog box before you send the document to the printer.
