ASS to WebVTT Converter

Convert ASS subtitles to WebVTT with the timings preserved.

To convert ASS to WebVTT, paste the subtitle file above and the converted output appears immediately. Cue timings are preserved to the millisecond, and cues can be renumbered sequentially — which matters because several players silently stop at the first out-of-order index. WebVTT is required by the HTML5 <track> element, uses full stops for decimals and begins with a WEBVTT header line. It is the only format browsers play natively.

About converting ASS to VTT

ASS carries positioning, fonts and colours alongside the text. Converting to it produces valid but unstyled cues; converting away from it discards the styling entirely. WebVTT is required by the HTML5 <track> element, uses full stops for decimals and begins with a WEBVTT header line. It is the only format browsers play natively.
