Canvas Won't Let Me Choose File: Troubleshooting Tips


As an online student or instructor, you may have encountered a frustrating problem when uploading files to Canvas. You select “Choose File” but nothing happens. Fear not! There are several solutions to this issue.

Clearing Your Browser Cache

The first step to take when facing this issue is to clear your browser cache. This will remove any stored data that may be causing the problem. To do this, go to your browser settings and select “Clear browsing data.” Check the box next to “Cached images and files” and hit “Clear data.”

Using a Different Browser

If clearing your cache doesn’t work, try using a different browser. Sometimes certain browsers have compatibility issues with Canvas. Switching to a different one may solve the problem.

Checking Your File Type

Make sure that the file you are trying to upload is in a compatible format. Canvas accepts a variety of file types, including PDFs, Word documents, and images. If your file is not in one of these formats, you may need to convert it.

Checking Your File Size

Another issue that may cause problems with file uploads is the size of the file. Canvas has a maximum file size limit of 500MB. If your file exceeds this limit, you will not be able to upload it. Check the size of your file and make sure it falls within the acceptable range.

Checking Your Internet Connection

Slow or unstable internet connections can also cause issues with file uploads. Make sure that you have a strong and stable connection before attempting to upload a file. If your connection is weak, try moving closer to your router or resetting it.

Enabling Pop-Ups

Some browsers block pop-ups by default, which can prevent Canvas from opening the file selection window. Check your browser settings and make sure that pop-ups are enabled for Canvas.

Disabling Browser Extensions

Certain browser extensions can interfere with Canvas and cause issues with file uploads. Try disabling any extensions that you have installed and see if that solves the problem.

Updating Your Browser

Outdated browsers can also cause compatibility issues with Canvas. Make sure that your browser is up to date by checking for any available updates.

Reporting the Issue

If none of these solutions work, it may be a technical issue with Canvas itself. Report the problem to Canvas support and they will investigate the issue.
