What Is PST to ICS Conversion?
PST to ICS conversion extracts Outlook calendar events from a Microsoft Outlook PST file and saves them in iCalendar (ICS) format. ICS is the universal, portable calendar format supported by Google Calendar, Apple Calendar, and most scheduling and calendar applications.
PST (Personal Storage Table) stores email, calendar, contacts, and notes in one file. This tool reads the PST on your device, parses calendar items (appointments, meetings, all-day events), and outputs standard iCalendar so you can import into Google Calendar or Apple Calendar without Outlook.
The converter runs 100% on your device — no upload, no server, no Outlook installation. You can add multiple PST files and export all calendar events to one merged ICS or separate ICS files per source. Recurring events and basic metadata (title, time, description, location) are preserved.
Use PST to ICS when migrating from Outlook to another calendar system, backing up your schedule in a portable format, or moving events to a new device or cloud calendar. ICS keeps events in a widely supported, vendor-neutral format.
