💡 Converts between SRT, WebVTT, SBV (YouTube), LRC (lyrics), and ASS/SSA, preserving timing. The input format is detected automatically. Everything runs in your browser — your captions are never uploaded.

WebVTT tips

🌐

The HTML5 <track> element requires WebVTT, not SRT — converting lets your captions work on the web.

⏱️

Timing is preserved exactly; SRT's comma milliseconds become VTT's dot format automatically.

📋

Copy the output straight into a .vtt file referenced by your <video> element.

🔒

Captions are converted in your browser — never uploaded.
