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 you start

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.

Solution 1Recommended

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.

1
Identify fillable fields

Open your PDF and look for highlighted interactive fields. Do not open the 'Fill & Sign' tool from the side panel.

2
Enter information directly

Click directly into the highlighted text boxes, checkboxes, or radio buttons to input your information natively.

3
Save your progress

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 Native Interactive Form Fields
Data Retention: Using native fields guarantees that your text inputs act as distinct interactive objects rather than being merged with the document's background.

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.
