User Reviews
Hi there, I don't actually use this because the extension only works on what I assume is your university's canvas page, so I was wondering if you could make this to work for all canvas/instructure domains. If not I hope you could add the source code/repo so that I and others could change it for our needs or even make it universal.

This extension is the best canvas formatter extension out there. You will NOT find a better, easier, quicker extension that will save you as much hassle for canvas as this one will. One click to install and it immediately fixes the deadspace on canvas when looking at a file. 10/10 definitely recommend.

Is Canvas File Formatter Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Canvas File Formatter requires very minimum permissions.
