How to make an ics file

Apple's iCalendar application lets you create and share appointments with other iCalendar users, who export and import this information with ICS formatted files. The ICS format has found acceptance with other calendar applications, such as Google's Web-based calendar and the popular Microsoft Outlook application. This widespread acceptance has made it possible for one person to invite another person to an event simply by sending an ICS file.

Skill level:


  1. 1

    Open the appointment that you wish to place in the ICS file.

  2. 2

    Open the "Save as" menu. Click "File" from the toolbar at the top of the screen, and then click "Save as."

  3. 3

    Enter a file name, and select "iCalendar Format" from the "Save as type" menu bar.

  1. 1

    Select the iCalendar event that you wish to place in the ICS file.

  2. 2

    Drag the event from the calendar and place it on your desktop. Dragging an iCalendar event to the desktop automatically creates an ICS file.

  3. 3

    Attach the ICS file to an e-mail, and send it to event invitees.

  1. 1

    Open the calendar settings. Select the white down arrow in the small blue box next to the name of the calendar in the far left column. Click on the "Calendar settings" submenu.

  2. 2

    Select the green "ICAL" icon.

  3. 3

    Copy the link. This link allows access to a new ICS file that contains your calendar's events.

Tips and warnings

  • ICalendar users may place multiple events in an ICS file. To access this feature, open your calendar of choice, choose "File" from the top toolbar and then choose "Export."
  • Outlook users cannot create an ICS file with Outlook's export function. Outlook does not export into an ICS format. Outlook users must use the "File" > "Save as" option to save ICS data.
