Result

This page opens the subtitle converter with VTT → SRT conversion already selected — load your .vtt file or paste its content, run the tool and download the .srt result.

The converter strips the WEBVTT header, rewrites dot timestamps into the SRT comma form, renumbers every cue sequentially and removes VTT-only markup. SRT has no place for WebVTT positioning or styling, so the tool honestly reports how many cues lost such data instead of pretending nothing happened.

Everything runs locally in your browser: captions are never uploaded, and the same tool can also shift timing when the converted subtitles start too early or too late.

Executed in Browser

Your files and inputs never leave this device. Processing runs completely offline. 100% Secure.

Accepted Formats & Rules

  • Convert SRT to WebVTT and WebVTT to SRT with correct timestamp separators and sequential renumbering.
  • Shift all timestamps forward or backward by milliseconds or seconds; negative results are clamped at 00:00.
  • Load a .srt or .vtt file or paste subtitle text, then download the result with the right extension.

Key Benefits

✓ Complete privacy: subtitle files are parsed and rebuilt entirely in your browser and never uploaded to a server.
✓ Tolerant parser: BOM markers, Windows line endings and stray blank lines between cues do not break the conversion.
✓ Honest conversion notes: when VTT positioning or styling cannot survive the trip to SRT, the tool says exactly how many cues were affected.

Use Cases

  • • Convert a downloaded .srt file to WebVTT so the captions finally load in an HTML5 video player or on a web platform that only accepts .vtt.
  • • Fix out-of-sync subtitles by shifting every timestamp a few hundred milliseconds forward or backward until they match the speech.
  • • Renumber the cues of a subtitle file after cutting or merging scenes, so editors and players stop complaining about broken sequence numbers.
