What types of files can I preview in Canvas?

You can preview a variety document types in Canvas. If the submitted file is an assignment and a Canvas DocViewer supported file type, the file is rendered by DocViewer in SpeedGrader. If the submitted file is not an assignment or a DocViewer supported file type, the file is rendered by Google Previewer.

Canvas supports previews for documents up to 100 MB and 999 pages.

Notes:

  • SpeedGrader may take up to ten minutes after an assignment is submitted to display a document that supports DocViewer.
  • Files over 30 MB need to be downloaded to view.

Troubleshooting Tip: If an uploaded file does not display a preview, try uploading it as a different file type.
