What is an ICS file?
An .ics file — short for iCalendar — is the universal file format for sharing a calendar event between applications. It's a plain‑text file defined by RFC 5545 and contains everything about an event: title, start and end time, timezone, location, description, attendees, reminders, and recurrence rules.
Because it's an open standard, .ics files are read by every major calendar — Google Calendar, Google Workspace, Microsoft Outlook, Outlook 365, Apple Calendar, Yahoo, Thunderbird and dozens more. If you've ever clicked an "Add to Calendar" link in an email, you've probably downloaded an .ics file.
Why convert ICS to a Google Calendar link?
Google Calendar can import .ics files natively, but the path is buried. The recipient has to download the file, open calendar.google.com, dig into Settings, find Import & export, browse to the file, pick a destination calendar, and confirm. For a single one‑off invite — a webinar, a launch, a meeting — that's a lot of friction for the person you're inviting.
A direct Google Calendar event‑edit link skips every step. One click and the event opens inside Google Calendar with the title, time, location, description, timezone, and even the recurrence rule already filled in. It's the cleanest way to share a single event with anyone using Google Calendar or Google Workspace — and it works in any browser, on any device, signed in to any Google account.
Personal Google vs Google Workspace
Generated links use the same calendar.google.com endpoint regardless of which Google account a user is signed in to, so personal Gmail and Google Workspace accounts both work without changing anything in the tool.
Personal Google
For personal Google accounts at calendar.google.com. Use if your email ends in @gmail.com, or any non‑Workspace Google account.
Google Workspace
For work or school accounts on Google Workspace — same URL, same flow. The event is added to your work calendar (or whichever destination calendar you pick).
The only practical difference: a Workspace admin can restrict imports on shared calendars. If you don't see your team calendar in the destination list, import to your personal calendar or ask your admin to grant access.
