Product
Adobe Acrobat Pro DC
Device & OS
not provided
Scenario
Trying to manually fill out a PDF document, add checkboxes, or strike out text using the Fill and Sign tool after a software update.
Observed behavior
The annotation toolbar is missing or disabled within the Fill and Sign feature, preventing users from adding custom marks and signatures.
Before you start

Check if the PDF document already contains interactive, fillable form fields, as Acrobat automatically restricts custom annotation tools to prevent interference with the designed form elements.

Solution 1Recommended

Fill Interactive Form Fields Directly

Use this method when the PDF is already designed as an interactive form.

When Adobe Acrobat detects fillable form fields within a PDF document, it intentionally disables the manual annotation tools. This is to ensure that the user completes the form exactly as the creator intended by clicking directly into the designated fields.

1
Identify interactive fields

Hover your mouse over the areas of the document you need to fill. Look for blue highlighted boxes or fields that change your cursor into a text I-beam.

2
Enter data directly

Click directly into the text boxes to type, or click on checkboxes and radio buttons to toggle them without needing the manual Fill and Sign toolbar.

Fill Interactive Form Fields Directly
Automatic Tool Disabling: If you absolutely must use custom annotations on an interactive form, you may need to print the document to PDF first to flatten the interactive fields, turning it into a standard document.

Frequently Asked Questions

Why does Adobe Acrobat disable annotation tools on some PDFs?

Acrobat automatically disables manual annotation tools like checkmarks or lines if the PDF is detected as an interactive fillable form. The software expects you to click and type directly into the designated form fields instead of adding loose annotations.

Where can I find the Fill and Sign tools in the latest Acrobat update?

In the newest versions of Acrobat Pro DC, the manual annotation tools (Crossmark, Checkmark, Circle, Line, and Dot) are located directly within the Fill & Sign toolbar, provided you are opening a non-interactive PDF.

How do I add a checkmark to a PDF without interactive fields?

You can use the Fill & Sign feature, select the checkmark icon from the top toolbar, and then click anywhere on the document to manually place the checkmark. If the tools are missing, ensure your software is updated.
