How do I restrict online submission file types for an assignment in my course?

Canvas recently introduced a new page design called the New Canvas User Interface (UI). Depending on your Canvas view, your page design may vary from the images shown in this lesson. However, the functionality and location of the components remain the same.

If you want to only allow certain types of files for assignment submissions, you can restrict the upload file types when adding assignment details.

In the case of restricting assignments with an odd or unusual file type, try adding it to your course to confirm the file is accepted before requesting students to submit the file type.

Google Drive File Types

If your institution has enabled Google Docs (at the account level) as an assignment submission type, students can connect to Google Docs as a web service to submit an assignment as a Google Doc (.gdoc), Google Sheet (.gsheet), or Google Slide (.gslide). They can also use Google Docs to submit uploaded Word (.doc/.docx), Excel (.xls/.xlsx), PowerPoint (.ppt/.pptx), and PDF files not converted to Google Docs formatting.

When Google file types are uploaded as a submission, those files will convert to their Microsoft counterpart file types and appear in the submission as respective Word, Excel, or PowerPoint files. However, the opposite is not true—Canvas does not individually recognize Google Drive files (.gdoc, .gsheet, .gslide) as supported file types. If you want to allow students to submit Google file types, do not select the upload file type restriction.

Turnitin File Types

If your institution has enabled Turnitin (at the account level) for assignment submissions, Turnitin accepts various file types and images.
