Frequently asked questions
Can I bring in a course built in another authoring tool?
Yes, if it's a SCORM package. Coassemble converts packages from Articulate Rise and Storyline, Adobe Captivate and iSpring into editable Coassemble courses, and lists anything that couldn't be converted.
How big can a SCORM package be for conversion?
Up to 1GB.
What's the file size limit for document transformation?
50MB. For larger files, split the content into smaller documents before uploading.
Can I upload a Google Slides file?
Not directly. Export it as a .pptx file first.
What's the maximum video upload size?
1GB. For larger videos, compress them below that limit, or embed a YouTube or Vimeo link instead.
