About this conversion
ASS subtitles carry fonts, colours and positioning that an HTML5 `<track>` element can't render. Converting to WebVTT gives browser-ready captions: the `{\style}` override tags and drawing commands are reduced to plain text, `\N` becomes a line break, and the centisecond timing is rewritten to `HH:MM:SS.mmm` under the required `WEBVTT` header so the cues load in any `<video>`.
Everything runs locally in your browser — the file is never uploaded.
