Product

Device & OS
not provided
Scenario
Attempting to enter text into specific areas of a scanned or password-protected PDF form.
Observed behavior
Acrobat XI reports that the PDF is secured or contains no editable text, which prevents the user from typing in the form fields using standard text editing tools.

Check the document properties (File > Properties > Security) to confirm if the PDF is secured with a password that explicitly restricts filling out form fields.

Solution 1Recommended

Use the Fill & Sign Tool for Scanned Forms

If the PDF is a scanned document without interactive form fields, you can use the Fill & Sign tool to manually add text over the document.

Scanned documents are treated as flat images by default. To enter text, you should avoid the standard 'Edit Text' tool and instead use features designed for non-interactive forms.

1
Open Fill & Sign

Open the scanned PDF in Acrobat XI and click on the 'Fill & Sign' option located in the right-hand task pane.

2
Select the Text Tool

Click on the 'Add Text' tool from the Fill & Sign menu.

3
Type your information

Click anywhere on the scanned form where you need to enter information and begin typing. You can drag the text box to position it perfectly on the form lines.

Alternative option: You can also use the 'Prepare Form' tool if you want to permanently add interactive fields to the scanned document for others to fill out.

Frequently Asked Questions

Why does Acrobat XI say my PDF has no editable text?

This usually happens when the PDF is a scanned image rather than a text-based document. You need to use the Fill & Sign tool to place text over the image, or run Optical Character Recognition (OCR) to convert the image into editable text.

Can I fill out a PDF if I don't have the permissions password?

If the document owner has strictly restricted form filling and commenting through security settings, you cannot fill it out digitally without the password. You may need to print the form and fill it out manually.

Is it safe to continue using Acrobat XI for PDF forms?

Acrobat XI was officially discontinued years ago and no longer receives critical security updates. It is highly recommended to switch to a modern, supported PDF editor like WPS Office to ensure document security and compatibility.
