Free ICS viewer Open and read any .ics file =========================== Upload an .ics or iCalendar file and see every event it contains: dates, times, locations and recurrence rules.

The builder on our homepage gives you one link that adds the event in a single tap on any calendar, stays editable afterwards, and tells you who added it. Includes 10 events a month and 50 RSVPs per event at no cost. The free tool below still works if you just need the raw output.

Choose an .ics file Or paste the file contents Read pasted calendar What is an ICS file? ---------------------- An ICS file, sometimes called an iCalendar file, is the standard format calendar apps use to exchange events. It is plain text, defined by RFC 5545, and every major calendar app can read it: Google Calendar, Apple Calendar, Outlook, Office 365 and Yahoo. Inside the file, each event is a `VEVENT` block holding a title, a start and end time, and optionally a location, description and a recurrence rule. Because it is just text, an ICS file is easy for machines to read and almost impossible for a person to read at a glance, which is what this viewer is for. How to open an ICS file ------------------------- - **To read it:** upload it above. - **On a computer:** double click the file and your default calendar app offers to import it. - **Google Calendar:** Settings, then Import and export, then choose the file. - **Outlook:** File, Open and Export, then Import an iCalendar file. Sending events to other people? --------------------------------- An .ics attachment works, but plenty of recipients cannot open one on a phone, and any change you make later never reaches them. An [ add to calendar link ](https://addcal.co/solutions/add-to-calendar-links.md) adds the event in one tap on whichever calendar they use, and stays up to date if the event changes.

An ICS file (also called an iCalendar file) is the standard format for sharing calendar events. It is a plain text file that stores an event's title, start and end time, location, description and recurrence rules, so any calendar app can read it. ### How do I open an ICS file? Upload it above and every event will be listed in your browser. To add it to a calendar instead, double click the file and your default calendar app will offer to import it, or use Google Calendar's Settings, Import and export screen. ### Is my file uploaded anywhere? Your file is sent to our server only to be parsed, and the contents are never stored or logged. Nothing is written to disk and nothing is kept once the response is returned. ### Why does my recurring event only show once? Repeating events are stored once with a recurrence rule rather than as hundreds of copies. We show the first event along with its rule, for example weekly on a Tuesday, instead of expanding every occurrence. Free forever, start in 30 secondsFill your next event's seats.
