Convert IGC to Markdown.
Drop a glider flight log and get a clean Markdown summary of its header. It runs entirely in your browser, so your file never leaves your device.

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.
A flight log,
at a glance.
An IGC file packs the pilot, glider and date into coded header lines, then thousands of raw B-record fixes. The converter pulls out the header and a fix tally as readable Markdown.

Flight header and fixes
The pilot, glider and date headers come through, with a count of the position fixes.
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 flight log or a thousand; it all runs the same way, on your own device.
What lands
in Markdown.
Honest about what comes through, and what doesn't. These are the same notes the Formats list shows for IGC, so the page never drifts from what the converter really does.
Kept
4- Pilot name
- Glider type
- Flight date
- Fix count
Dropped
2- Fix coordinates and altitudes
- Other log records
IGC questions,
answered.
Everything worth knowing before you drop in a flight log.
