ICS file splitter

Split a large calendar into smaller, independently importable files.

Calendar file

Event visibility

“Google Calendar default” removes the ICS CLASS property. This is intended to map to Google’s default visibility; test one chunk before a bulk import.

Maximum file size (MB)

Uses decimal MB. The default 0.95 MB provides a safety margin below a 1 MB upload limit.

Private by design: your calendar is processed entirely in this browser and is never uploaded.
