You can enter a website URL as a submission in a Canvas course that uses Assignment Enhancements. When a URL is submitted as an assignment, Canvas takes a screenshot of the web page at the time it was submitted. This lesson shows how to turn in a standard online assignment in a course using Assignment Enhancements. You may also have the option to resubmit assignments if your instructor allows.

Before submitting an assignment, you may want to review all assignment information, such as the assignment rubric.

Third-Party File Application Submissions

You can submit assignments from Google Drive, Dropbox, or another third-party service via your desktop computer in one of two ways:

• Download the file to your computer and submit as a File Upload
• Share the file, copy the file URL, and submit as a Website URL

Notes:

• If the assignment you are accessing displays differently, Assignment Enhancements may not be enabled in your course or your instructor may not have used a supported assignment type. Please view this guide for more information.
• Assignment Enhancements does not support the following assignment types: No Submission, Group Assignments, Peer Reviews, and Cloud Assignments.
• Not all file types may be available for your assignment, depending on the assignment submission type set by your instructor.
• Not all of your assignments may be submitted online. If you cannot see options to submit your work, your instructor may want you to submit your assignment in a different way or the assignment is not within its availability dates. View the assignment header and details for instructions, or contact your instructor for assistance.
