Canvas Upload Limit: Submitting and Storing Large Files

Canvas Upload Limits Explained


Canvas restricts the size of any uploaded file to 5Gb and just 500Mb for student video submissions. With video becoming an increasingly popular medium within Education, and technology creating higher quality video with bigger and bigger file sizes, this is becoming quite a big limitation for a lot of users. Especially with the increasing popularity of uploading directly from a mobile.

In addition, these large files take up a lot of storage quickly and some systems charge a premium for this and can often lead to hidden and ever increasing charges.

At an average bitrate of 100mbps, 1 minute of 4k video recorded on a mobile is roughly 7.5Gb, so this quickly ramps up, eating your storage surprisingly quickly. This is generally the default recording on a mobile device now, unless a user proactively changes their settings.


Ways to Reduce Video File Size


Most videos that we are recording and sharing are seen on a computer screen or mobile so would not be seen at 4k or possibly 1080p anyway, so why generate these massive files, it’s a waste of time (waiting for uploads) and storage.

There are steps that can be passed on so users can reduce their file sizes easily. This will not only help administrators from a storage perspective, but also hugely help the users themselves.

Students can get very frustrated when uploading from a mobile and the upload is interrupted because their screen automatically locks after a few minutes, or the internet momentarily dropped or swapped to 4G.


  • It is easy in the Camera Settings of a device to lower the default resolution (seen here on an ios device):



  • To something much more sensible, like:



  • This simple adjustment could make the recording up to x10 smaller!!


These files can be uploaded, but often it is quicker to dump them into something like Dropbox or Google Drive, they can then be downloaded on a computer and even compressed further. There are many tools out there, for example Miro Converter, which is FREE for PC or Mac.


Using an App to Store Large Files


Remember Canvas restricts file size to 500Mb for students, well MEDIAL allows configurable upload size within Canvas up to 100Gb per user or group as an overall, or can be set as a recurring monthly limit.
