How do I use DocViewer in Canvas using Assignment Enhancements as a student?
Canvas DocViewer is a tool that allows annotations on uploaded online assignment submissions in Canvas. In assignment details, you can use DocViewer to view annotated feedback from your instructor or from other students in peer review assignments. You can also use DocViewer when submitting peer review feedback.
Session Limits
DocViewer has a 10-hour session limit that begins when you open a submission. If you start to make an annotation but do not submit it before the session expires, the annotation will not be saved. Canvas will display a session expiration warning at 9 hours 50 minutes, followed by a 5-minute and 1-minute warning until the 10-hour limit has been reached. You can restart a DocViewer session at any time by refreshing the submission page.
If your browser includes a built-in PDF viewer, select the option to view the PDF in the system viewer.
Compatible DocViewer Files
If a submission includes a file that can be rendered in DocViewer, but the submission preview is not yet complete, Canvas will generate a message stating the document is still processing.
Accessibility
You can access DocViewer annotations and comments with a screen reader, which can read the annotation, author name, comments, and any reply comments at the end of the document. However, the following limitations currently exist: when you are listening to your document, there is no indication that a comment is available; if you are tabbing through comments, you cannot jump to the associated place in the annotated assignment; the kind of annotation is not indicated; some images may have no alternate text or display; markers in the document are not in-line with the text.
Notes:
- If you cannot annotate a document in DocViewer, your institution may have restricted this feature.
- Files over 100 MB and password-protected files will not be converted by DocViewer.
- DocViewer annotations can be viewed in the Canvas Student app.
- Your instructor can delete any comment or annotation at any time.
- If your instructor anonymously grades an assignment, annotations in DocViewer will not be available until the assignment is unmuted.
- Submitted annotations are saved and are not affected by the session limit.

To access DocViewer, view feedback from your instructor or peer review feedback on the assignment details page. The Review Feedback displays an indicator if annotated comments have been added to a supported assignment.
