What is the Wiki file size limit?
The Wiki limits attachment size to 15MB per uploaded file.
However, Technology Services does not recommend storing large files (greater than 10 MB) directly on the wiki.
If you have a need to store large files, the suggested approach is to upload your files to UofI Box and link to them from your wiki space. You can also find suggestions and help on reducing file sizes in some situations in the Illinois Wiki Documentation: Attaching Large Files
