Convert TTML to Markdown.
Drop a .ttml or .dfxp caption file and read every cue as plain text, each line tagged with its begin time. It runs entirely in your browser, so your file never leaves your device.
Drag & drop your files

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.
Wrapped in
timing tags.
A TTML file buries each line inside styled regions and timing attributes. Converting lifts the spoken text out, keeping its begin time and dropping the XML scaffolding around it.
<tt><body><div>
<p begin="00:00:01">Hello there.</p>
<p begin="00:00:05">General <span tts:fontWeight="bold">Kenobi</span>.</p>
</div></body></tt>
**[00:00:01]** Hello there.
**[00:00:05]** General Kenobi.
Everything you
actually need.
Timed-text captions in, readable Markdown out, with no server and no account anywhere.
It never leaves your browser
Your .ttml is read 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.
[00:00:01] Hello there.
[00:00:05] General Kenobi.
Timed paragraphs flattened
Each timed paragraph keeps its text and begin time; the regions and nested styling are flattened.
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 caption file or a thousand; it all runs the same way, on your own device.
Text out,
markup gone.
Honest about what comes through, and what doesn't. These are the same notes the Formats list shows for TTML, so the page never drifts from what the converter really does.

Everything worth knowing before you drop in a caption file.
