Frequently asked questions
- How do I convert SRT to VTT?
- Drop your .srt file into the converter above or tap to choose it. It is converted to WebVTT instantly in your browser and the .vtt download starts automatically — free, no signup, no upload.
- Why do I need a VTT file instead of SRT?
- HTML5 video players, the <track> element, and platforms like Vimeo, Wistia, and many LMS tools require WebVTT. If your captions came as .srt, converting to .vtt makes them web-ready.
- Does the converter add the WEBVTT header?
- Yes. A valid WebVTT file must start with a WEBVTT line — the converter adds it and rewrites every timestamp from comma milliseconds (00:00:01,000) to dot milliseconds (00:00:01.000).
- Are my files private?
- Completely. The conversion is done by JavaScript running on your own device. Nothing is uploaded, logged, or stored.
- Does it support Chinese, Cantonese, and other non-English subtitles?
- Yes. Files are handled as UTF-8 end to end, so CJK characters, accents, and emoji survive the conversion untouched.
- Can I convert multiple formats, not just SRT?
- This page is optimized for SRT to VTT. For SBV or any-to-any conversion, use our universal subtitle converter — it is just as free and private.
