Why annotate PDFs on Windows 10?

Windows 10 includes Microsoft Edge as the default browser, and you can use the Microsoft Edge PDF viewer to edit PDFs for free, directly in the browser. There is no “annotate” button. You can draw or write on the PDF, highlight text in different colors, or make a comment.

  1. Open Microsoft Edge and navigate to the PDF in the browser, or find the file on your computer and select Open with > Microsoft Edge.
  2. To draw or write freehand, select the pen icon from the toolbar. Click the downward arrow to select the color and size of the pen stroke.
  3. To highlight in a color, select the text you would like to highlight, right-click, and select Highlight from the drop-down menu. Then select the color.
  4. To comment, select the text you would like to comment on, right-click, and select the comment icon from the drop-down menu.
  5. Type your comment in the box that appears.
  6. Save the comment by clicking the checkmark in the upper-right corner of the comment box.
  7. Save changes by clicking the floppy disk icon.

If you are using a fillable form in Microsoft Edge, select the text boxes that allow you to type directly in the PDF.
