- Product
- Adobe Acrobat Pro DC
- Device & OS
- not provided
- Scenario
- Adding freehand drawings, signatures, or handwritten notes to a PDF file using a graphics tablet.
- Observed behavior
- The user needs to know the correct tools to use, and handwriting added this way behaves as an image rather than searchable text due to Acrobat's lack of handwriting OCR.
Ensure your Wacom tablet is properly connected to your computer and that the latest device drivers are installed and functioning before launching Adobe Acrobat Pro DC.
Use the Comment and Drawing Tool in Acrobat Pro DC
Utilize the built-in Drawing tool within the Comment section to add freehand writing or drawings using your Wacom tablet.
When you use a Wacom tablet to write on a PDF in Adobe Acrobat Pro DC, the software treats your handwriting as an image annotation.
Acrobat does not provide Optical Character Recognition (OCR) for handwritten text. This means your notes will remain as visual drawings and will not become searchable or editable text.
Launch Adobe Acrobat Pro DC and open the PDF file you wish to annotate.
Navigate to the right-hand pane and click on the 'Comment' tool to display the annotation toolbar at the top of the document.
Click on the 'Drawing tool' (represented by a pencil icon) located in the Comment toolbar.
Use your Wacom tablet pen to start writing, drawing, or adding freehand notes directly onto the PDF page.

Frequently Asked Questions
Can I convert my handwritten Wacom notes into text in Acrobat?
No, Adobe Acrobat Pro DC does not offer OCR (Optical Character Recognition) capabilities for handwriting. Any text written with the drawing tool is saved as image content and cannot be converted into searchable or editable text.
Why isn't my Wacom pen pressure working in Acrobat?
Acrobat's basic comment tools may not fully support advanced pen pressure sensitivity natively. Ensure your Wacom drivers are up to date, or customize the drawing line thickness manually in the properties bar after selecting the pencil tool.
How do I erase mistakes when writing on a PDF?
While in the Comment toolbar, you can select the Eraser tool (next to the Drawing tool) to remove specific parts of your drawing, or simply select the entire drawing annotation with the Selection tool and press Delete on your keyboard.
