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.
