Exports from Google, Apple or Outlook Calendar · duplicate events are removed

Free forever · nothing uploaded

One calendar file instead of five

Leaving a job and want your personal events out of the work account? Moving from Outlook to Google? Consolidating the family's calendars? Calendar apps import one file at a time and happily create duplicates. This tool merges all your .ics exports into one clean file — events deduplicated by their unique IDs, recurring events and time zones preserved exactly — so a single import puts everything in place.

Exporting your calendars

  • Google Calendar: Settings → Import & export → Export (downloads .ics per calendar).
  • Apple Calendar: File → Export → Export… per calendar.
  • Outlook: Calendar settings → Shared calendars → publish/export .ics.

Merge them above, then import the single result wherever you're headed. Like every AIMerger utility, your events — meetings, appointments, private plans — never leave your device.

Frequently asked questions

How do I merge two ICS calendar files?

Export each calendar as .ics, drop the files into the tool above, and click Merge. Duplicate events are removed and you download one combined .ics file to import into any calendar app.

Will recurring events and time zones survive the merge?

Yes — events are kept exactly as exported, including recurrence rules and time-zone definitions. Duplicates are detected by each event's unique ID, so nothing legitimate is lost.

Can I import the merged file into Google Calendar?

Yes — in Google Calendar go to Settings → Import & export → Import and select the merged .ics. It also imports cleanly into Apple Calendar and Outlook.

Is my schedule uploaded anywhere?

No — merging runs entirely in your browser. Your events never leave your device.
