What is a Large File?

  • Email: Anything over 5 megabytes
  • Canvas: Anything over 100 megabytes, but we support up to 250 megabytes per file
  • OneDrive: Up to 100GB per file. Your storage on OneDrive is 5TB! Learn more about OneDrive.

If you work with files that contain many images or video, you've probably noticed that these files can become very large. Large files can be difficult to share: they take longer to email, upload to Canvas, and they take up more space than needed. It also means that your potential audience also will struggle with the file. It's very easy to reduce the size of these files.
