Free ICS File Viewer
Open an ICS calendar file in your browser to see its events before importing it. Review common details, make careful edits, and export a fresh ICS file when needed.
How it works
- Choose an ICS file: Open a .ics calendar file directly in your browser.
- Inspect and edit events: Review titles, dates, times, locations, notes, and common recurrence rules.
- Export an updated copy: Download a new ICS file when your changes are ready.
Limits and privacy
ICS files stay in the browser and are limited to 2 MB. The viewer supports common VEVENT fields and simple recurrence rules; it warns before an edited export could omit advanced iCalendar features.
Free ICS File Viewer questions
Is my ICS file uploaded?
No. Alfova parses the ICS file in your browser; private calendar data does not leave your device.
Which ICS details can I edit?
You can inspect and edit common event title, start, end, location, and notes fields, then export a new ICS file.
What are the viewer limitations?
The viewer preserves simple RRULE recurrence rules. Alarms, attachments, exceptions, and advanced recurrence exceptions are shown with a warning and are not retained after an edited export.
