To set this up, follow the instructions below with an existing assignment in Canvas. If you need help to set up your assessments in Canvas, view our online learning materials.

  1. Select Submission Type for your Assignment and set it to Online.
    • Choosing Online from the menu will give you a series of options including File Uploads.
  2. Check File Uploads.
  3. Check Restrict Upload File Types. A text entry box will appear where you can type in Allowed File Extensions.
