We support doc, docx, odt, txt or rtf files with a maximum word count of 8,000 words and file size under 4 MB.  

Note: your institution might set a different word limit, which will be flagged in an error message at the time of uploading your document.

We do not support PowerPoint presentations or PDFs, so if your document is written in this format, you'll need to copy the content into a word document before you upload it.
