How do I use DocViewer in Canvas assignments as a student?

Canvas DocViewer is a tool that allows annotations on online assignment submissions in Canvas. If DocViewer has been enabled for your institution, you can use DocViewer to view files and assignments in SpeedGrader. You can view when students view annotated feedback in the assignment details section of the sidebar.

When you open a submission, DocViewer will automatically save any annotations made to the submission file for one hour. You can restart a DocViewer session at any time by refreshing the submission page. To help you avoid losing work, Canvas will generate a session expiration warning after 60 minutes.

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.

Notes:

  • Currently, annotations cannot be downloaded.
  • Files over 100 MB and password-protected files will not be converted by DocViewer.
  • SpeedGrader may take up to ten minutes after an assignment is submitted to display a document that supports DocViewer.
  • DocViewer annotations can be viewed in the SpeedGrader app.
