Convert iCalendar to Markdown.
Drop an .ics file and get every event as a readable Markdown section in seconds. It runs entirely in your browser, so your calendar never leaves your device.
Drag & drop your files
or
Optimize for AI & RAG
Extra cleanup for LLM ingestion: strip HTML, fix smart quotes, tidy Unicode and spacing.
Add YAML front matter
Prepend a metadata block (title, source, date, word & token counts) for knowledge bases and RAG.
Add table of contents
Build a linked index from the headings. Handy for long documents.
Export RAG chunks (.json)
Split the result into retrieval-ready chunks. Download per file from the result panel.
Most converters quietly upload your documents to a server. This one physically can't.
Built for apps,
not for reading.
An .ics file packs events into terse VEVENT blocks meant for calendar apps. Open one and you face raw property lines and packed timestamps. Converting turns each event into a plain Markdown section you can read.

Everything you
actually need.
Calendar files in, readable Markdown out, with no server and no account anywhere.
It never leaves your browser
Your .ics is read and parsed on your device. Nothing is uploaded to any server, ever.
# Heading
- point one
3 chunks
AI & RAG ready
Optional cleanup, YAML front matter, a table of contents and RAG chunk export.
Works offline
Once the page has loaded you can switch off your connection and it keeps converting.

- Start: 10:00

Each event, a section
Every event becomes a heading from its summary, with its times and location as bullets.
Unicode safe
Accents, symbols and non-Latin scripts come through intact as UTF-8.
Free, and unlimited
No sign-up, no quotas, no watermarks. Convert one file or a thousand; it all runs the same way, on your own device.
What survives
the trip.
Honest about what comes through, and what doesn't. These are the same notes the Formats list shows for iCalendar, so the page never drifts from what the converter really does.
Kept
