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.
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.
