Known issues
- This is a large editor: the first start downloads about 34.7 MB before compression, so it can take a while on a slow connection. Your browser keeps it afterwards.
- The editor's own documentation says it is a beta that still needs testing against real-world DOCX files, and that charts and SmartArt are not kept.
- The tests above ran on a local test server, before this site went live.
When to keep the original software
Keep using the desktop word processor for documents with charts or SmartArt, complex templates, or live co-editing with a team.
