Solve PDF export problems under Confluence Cloud
draw.io for Confluence Cloud may have problems generating a PDF of your diagrams if they are too large.
Note: This only applies to Confluence Cloud, and not Confluence Server.
Huge diagrams might cause a timeout on the diagrams.net servers that generate the PDFs. This might result in a blank or corrupt PDF being returned.
If you have this problem instead of exporting to a PDF, please print your diagram to a PDF file.
