SSA to WebVTT Converter

Convert SSA subtitles to WebVTT with the timings preserved.

To convert SSA 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 SSA to VTT

SSA is the predecessor of ASS and is read with the same parser. Output is written in the newer ASS form, which players treat as a superset. 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.
