Subtitle to WebVTT Converter
Convert an SRT or VTT subtitle file to clean WebVTT for HTML5 video, with correct timestamp formatting and a valid WEBVTT header.
HTML5 video's <track> element requires WebVTT, not SRT. This produces a valid WEBVTT file (correct header, dot-separated milliseconds) you can drop straight into a web player. Paste either SRT or VTT in — it normalizes both to spec-clean WebVTT.
🔒 Subtitles are processed entirely in your browser — never uploaded.
