Faculty, Staff and Students: How Can I Reduce the Size of My Files?
Updated: 03 March 2015 03:56 PM

What is a Large File?

  • Email: Anything over 5 megabytes
  • Canvas: Anything over 100 megabytes, but we support up to 500 megabytes per file
  • Cloud File Sharing Services (Google Drive, Dropbox, OneDrive): As big as your patience and your allocation. Check out this article on using Google Drive.

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.
