Many of the new iPads and iPhones have HEIC files for their photos. If a student is required to upload a file to Canvas this file isn't compatible with the speedgrader preview. In order for a teacher to view this, he or she must download each individual document and then open them. This is extremely cumbersome, time consuming, and takes up a lot of space. Is there any way that the HEIC files can be added to the list of files that automatically preview in speedgrader? The example I would use would be if a teacher gives her students a math problem to work out. She wants to see their work, so they must take a picture of the page, then upload that picture to Canvas. Using the new iPhones causes the picture to be in HEIC format which is not compatible for preview in speedgrader.

- Open the .heic file in Preview

- Save the file
- Upload the .jpeg version of the file

- Go to the Camera settings section
- Click Formats
- Select “Most Compatible”
- New photos will be saved as .jpeg
iPhone users that want to keep using .heic but still upload the right file to Canvas:
- Use the Canvas app
- When submitting the file, select “File Upload”
- In the page for choosing a file, use the “Camera” or the “Library” option. When using those options, the iPhone will take the picture as .heic but it will pass the Canvas app a .jpeg version automatically.
- Go to the Files app
- Hit the action button
- Click “Save Image”
- The .heic file is now available in the Photos app
- Follow the instructions for the scenario above, where the user uploads to the Canvas mobile app.
