About this conversion

YouTube's caption editor exports `.sbv`, but a site's HTML5 player needs WebVTT. This rewrites SBV's `H:MM:SS.mmm` cue timing to VTT's `HH:MM:SS.mmm` under the required `WEBVTT` header, and — like every conversion here — detects the file's text encoding instead of assuming UTF-8, so non-Latin captions don't come out garbled.

Everything runs locally in your browser — the file is never uploaded.
