Crocodoc is a tool that allows annotations on online assignment submissions in Canvas. When you open a submission, Crocodoc will automatically save any annotations made to the submission file for one hour.

Compatible Crocodoc Files

If a submission includes a file that can be rendered in Crocodoc, but the submission preview is not complete, Canvas will generate a message stating the document is still processing.

If a file is submitted that is not compatible with Crocodoc, the Canvas document previewer will still display the file, but Crocodoc markup and commenting will not be available.

Canvas currently supports .doc/.docx, .ppt/.pptx, and .pdf Crocodoc file formats.

Crocodoc Toolbar

The Crocodoc Toolbar helps you manage the assignment submission.

The Magnifying Glass icons allow you to zoom in and out on the submission.
The Comment icon allows you to add comments on the submission.
The Download icon allows you to download the submission file and/or the annotated submission file.
If there are multiple pages, the Page arrow icons help you advance through the submission to find the page you want to annotate.
