SRT vs VTT
SRT (SubRip) uses comma milliseconds and numbered cues, used by YouTube, Premiere, and CapCut. VTT (WebVTT) uses dot milliseconds and a WEBVTT header, the standard for HTML5 <track> captions. This tool converts between them losslessly.
Private by design
Conversion happens entirely in your browser, so your subtitle file never leaves your device. No signup, no upload, no limits.
