Convert SSA / ASS to Markdown.
Drop a .ass or .ssa subtitle file and read every caption as plain Markdown. It runs entirely in your browser, so your file 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 the screen,
not for reading.
An ASS file wraps each caption in timing fields and override tags like {\i1}. Converting lifts out just the spoken line and its start time as plain, readable Markdown.
[Events]
Format: Layer, Start, End, Style, Name, Text
Dialogue: 0,0:00:01.00,0:00:04.00,Default,,{\i1}Hello there.{\i0}
Dialogue: 0,0:00:05.00,0:00:07.50,Default,,General Kenobi.
**[0:00:01.00]** Hello there.
**[0:00:05.00]** General Kenobi.
Override tags removed, each line on its own with its start time.
Everything you
actually need.
Styled subtitles in, readable captions out, with no server and no account anywhere.
It never leaves your browser
Your .ass or .ssa is read and converted on your own device. Nothing is uploaded to any server, ever.
**[0:00:01.00]** Hello there.
**[0:00:05.00]** General Kenobi.
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.
**[0:00:01.00]** Hello there.
**[0:00:05.00]** General Kenobi.
Dialogue, styling removed
Each Dialogue line keeps its text and start time; the override tags and styles go.
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.
From timed lines
to clean text.
Honest about what comes through, and what doesn't. These are the same notes the Formats list shows for SSA / ASS, so the page never drifts from what the converter really does.
