Canvas allows you to add annotations to PDF files for assignment submissions. Available annotations include highlight, underline, squiggly, strikeout, free text, and drawing.
The images in this lesson are shown for a phone display, but unless otherwise noted, tablet displays mirror the same steps.
Notes:
- If enabled in the browser version of Canvas, you will see celebration animations when you submit an on-time assignment in the Student app.
- If you need to edit your PDF annotations, tap the file link in the assignment description and submit the assignment again.
- PDF annotations are automatically saved.
