What is WebVTT?
WebVTT (Web Video Text Tracks) is the subtitle format used by HTML5 <video> elements and most streaming platforms (YouTube, Vimeo, Plex, Jellyfin). It uses .vtt as its file extension.
Differences from SRT
VTT files start with a WEBVTT header and use a period (.) as the millisecond separator instead of a comma. This tool handles the conversion automatically.
