In Short

Should you desire to grade students' submissions offline, you have the option to bulk download students' submissions, markup them outside Canvas, and re-upload them back to your course.

Key Considerations

The Download and Re-Upload Submissions tools allow you to download student submission files into a .zip file. After you grade and markup the submissions, compress the grades files, and re-upload them to Canvas. The SpeedGrader will attach the annotated files to the student submissions. Do not change the file names in any way.

Step-by-Step

Bulk download the student submissions .zip file to your local computer. (Note: Move the .zip file from your downloads folder to the desired location on your computer. Unzip or decompress the file by opening it. Annotate and markup each student's submission with your comments and save it WITHOUT CHANGING THE FILE NAMES.)
Re-zip the annotated submissions by compressing them into a zip file, and select Re-upload Submissions.
Click Choose File to select the zip file (with the annotated files) from your computer.

Please note: While this tool will append annotated files to the assignment submissions, you will still need to enter individual grades using the SpeedGrader or the Gradebook. Students will view your comments by opening the annotated file under Assignment Comments.
