You can create online assignments for students to submit their assignments through Canvas.
When allowing file uploads as an online entry option, you can restrict certain types of files for assignment submissions. 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.
If your institution has enabled Google Docs, the Google Apps LTI, or the Microsoft Office 365 LTI, students can upload files from their respective Google Drive or OneDrive account directly. (If only Google Docs are enabled for your institution, students must connect to Google Drive as a web service to submit an assignment as a Google Doc, Google Sheet, or Google Slide.) You can allow Google Drive and OneDrive files as submission types by selecting the File Uploads checkbox when creating an assignment.
Google Drive File Types
Students can submit Google Doc (.gdoc), Google Sheet (.gsheet), or Google Slide (.gslide) files. 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 submitted as an assignment submission, those files will convert to their Microsoft counterpart file types and appear in the submission as respective Word, Excel, or PowerPoint files. Canvas uses the conversion file type for submissions (and to render supported file types as Crocodoc files in SpeedGrader), so if you want to restrict file types to only include Google file types, you must also include the file types for each respective Microsoft file type as well. For instance, if you want to only allow Google Slide submissions, you must include .pptx as a restrictive file type, otherwise Canvas will not show the .gslide files in the Google Doc tab.
Turnitin File Types
If your institution has enabled Turnitin, you can create a Turnitin assignment. Turnitin accepts various file types and images.
Select Online Entry Options
Select the online entry options you want to allow for the assignment. You can select up to four options:
Text Entry : Students can submit their assignment directly in the Rich Content Editor.
Website URLs : Students can submit a URL that fulfills the assignment.
Media Recordings : Students can submit an audio or video recording that fulfills the assignment. They can either record new media or upload existing media. Video and audio uploads to Canvas can be up to 500 MB.
File Uploads : Students can upload a file to fulfill the assignment. Additionally, if your institution has enabled Google Docs, the Google Apps LTI, or the Microsoft Office 365 LTI, students can upload files from their respective Google Drive or OneDrive account directly. If only Google Docs are enabled for your institution, students must connect to Google Docs as a web service to submit an assignment as a Google Doc, Google Sheet, or Google Slide.
Assignment settings are persistent to always remember and display the settings created or edited in the previous assignment in the course. Based on prior assignments, one or more of these options may already be selected for you.
Note: In SpeedGrader, please be aware that only the File Upload option can convert submissions for supported DocViewer file types.
Restrict File Types
If you allow file uploads, you can choose to restrict submissions to specific file types. To enable this option, click the Restrict Upload File Types checkbox . In the Allowed File Extensions field , enter a list of accepted extensions. All file types need to be separated by a comma. You can include spaces, caps, and periods in assignment file names.
Note: In the case of 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.
