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.

01Why

Built for video,
not for reading.

A WebVTT file wraps every line in timestamps, cue settings and a WEBVTT header. Converting strips that scaffolding and leaves readable, reusable Markdown.

WEBVTT

00:00:01.000 --> 00:00:04.000 line:80%

Hello there.

02Features

Everything you
actually need.

WebVTT captions in, clean Markdown out, with no server and no account anywhere.

It never leaves your browser

Your .vtt is read and converted on your own device. Nothing is uploaded to any server, ever.

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.

Captions, header stripped

The WEBVTT header, cue settings and NOTE comments go; each cue text stays with its start time.

éñü✓

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.

03Fidelity

What a cue
keeps.

Honest about what comes through, and what doesn't. These are the same notes the Formats list shows for WebVTT, so the page never drifts from what the converter really does.
