What types of documents can be previewed in Canvas?

Body

Canvas supports a variety of document types that can be converted in Canvas. If the submitted file is an assignment and Canvas DocViewer supported file type, the file will be rendered by DocViewer in SpeedGrader. If the submitted file is not an assignment or a DocViewer supported file type, the file will be rendered by Google Previewer.

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

Note:

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.
