ICS Toolkit

Create, inspect, and share reliable ICS events with reminders, time zones, validation, compatibility preview, autosaved drafts, and reusable templates.

Create, inspect, edit, and share calendar events with confidence.

ICS Toolkit is a practical utility for working with universal .ics calendar files. Build an event from scratch, import an existing file, review exactly what will be exported, then save it to Files, share it with another app, or add supported details directly to Apple Calendar.

CREATE COMPLETE EVENTS • Add titles, descriptions, locations, links, categories, status, visibility, and availability • Create timed or all-day events • Choose an explicit time zone • Configure daily, weekly, monthly, or yearly recurrence • Add multiple reminders • Embed photos and files with filename and MIME-type metadata

BUILD MEETING INVITATIONS • Add an organizer and attendees • Export standards-based meeting requests for compatible calendar and email apps • Keep a stable event UID for reliable revisions and updates • Catch missing or invalid organizer and attendee details before export

IMPORT WITHOUT LOSING THE IMPORTANT PARTS ICS Toolkit retains far more information when you open and export an event again, including reminders, categories, status, visibility, recurrence details, exception dates, attachment metadata, and unsupported properties that can be safely carried forward.

REVIEW BEFORE YOU SEND Every Create, Share, and Add to Calendar action opens a compatibility review. See errors, destination-specific warnings, an event summary, and the generated raw ICS. You will know when Apple’s EventKit cannot directly write data such as attendees or embedded attachments—and when sharing the ICS file is the better choice.

WORK FASTER • Your current event is autosaved as a draft • Save reusable templates for events you create often • Import multi-event calendar files and add supported data in bulk • Search for locations and choose any writable calendar

ICS is widely supported by Apple Calendar, Google Calendar, Microsoft Outlook, and many other calendar apps. Compatibility varies by destination, so ICS Toolkit makes those differences visible before you export.

Event files and drafts remain on your device unless you choose to export or share them. No account is required.
