Using a digital pen or touch to write directly on PDF files has been one of the top feature asks from Microsoft Edge insiders. We are pleased to announce that inking mode for PDF files has rolled out to all Insider Preview channels. With this new inking mode, users can fill out PDF forms and sign using ink or take notes directly on PDF files and save for later reference.

How to access inking mode

To access this feature, open any PDF file from your computer or from the web. In the toolbar that is seen on the top, you will see two new options – Draw and Erase. You can click or tap on the Draw button to enter inking mode. Once in this mode, you can use a digital pen, touch or even mouse to write on any part on the PDF file. You can use two finger swipe for panning the file or use pinch gesture to zoom in/out if you want to navigate the file while in inking mode. 

If you make any mistakes while writing or drawing on the document, you can use the eraser by clicking or tapping the Erase button. To erase ink strokes in the erase mode, just move the pointer across any ink stroke to erase it.

Once you are done marking up the file, you can use the Save button in the toolbar to save your work and all the annotations you made will get saved onto the file. You can reopen the file at any point to see the ink annotation on the file or edit them. You can also print the file along with the annotations in case you want to send out a copy of the annotated form, for example.

What’s next?

This is just the first step for inking support for PDFs. For inking, right now we offer basic support with one pen color and stroke size. We will build on this over time, supporting additional capabilities and quality enhancements. Following is the list of inking features the team is working on:

• Support for the pen back button (eraser button) to erase while in inking mode.
• Ability to select color and stroke thickness for ink
• Selection of additional pens, like highlighter pen
