It is not uncommon for users to want to upload their own content into our Lesson Library.

For Microsoft formats such as Powerpoint, Word, etc, LearnCube will automatically convert these to a PDF format in order to make it more user-friendly in the whiteboard.

We do this because PDF is a more universally reliable format (able to display on any device) and all users can annotate on a PDF embedded in the LearnCube whiteboard (users cannot annotate on a Powerpoint in the same way).

Also, we've found PowerPoints often become very large files when they include imagery and multi-media, video, etc.

What we recommend is to convert PowerPoints to PDF
