VTT to SRT Converter — WebVTT to SubRip Subtitles
Open the converterThis VTT to SRT converter turns WebVTT caption files into the SubRip (.srt) format that almost every desktop media player, transcription pipeline, and offline subtitle editor expects. The conversion runs entirely in your browser.
WebVTT is the format you get when you save captions from YouTube, Whisper, or HTML5 video tools. SRT is the format almost everything else expects — VLC, IINA, MX Player, ffmpeg subtitle filters, Premiere Pro, Final Cut, every commercial caption authoring tool. Converting from VTT to SRT is therefore one of the most common subtitle-tooling tasks.
The tool strips the WEBVTT header, drops any STYLE / NOTE / REGION metadata blocks that have no SRT equivalent, normalizes timestamps from `HH:MM:SS.mmm` to `HH:MM:SS,mmm`, and adds 1-based cue indices. Cue text, line breaks, and inline formatting tags pass through unchanged.
Because conversion is a regex-based text transform running in your browser, even long-form captions with thousands of cues convert in well under a second. Nothing is uploaded, so private or confidential transcripts never leave your device.
Frequently asked questions
Are my captions uploaded?
No. The transformation runs entirely in your browser as a text operation. Nothing is sent to a server.
What happens to VTT STYLE and NOTE blocks?
STYLE, NOTE, and REGION blocks have no SRT equivalent and are stripped during conversion. Only cue blocks (with timestamps and text) are kept.
Does the converter add cue indices?
Yes. SRT requires a numeric index above each cue. The tool adds 1-based indices automatically in cue order.
What if my VTT lacks the hour in timestamps?
VTT permits `MM:SS.mmm`; SRT requires `HH:MM:SS,mmm`. The tool pads the hour with `00:` automatically.
Are inline cue tags like <c.classname> preserved?
Yes, in the SRT output. Most SRT players ignore unknown inline tags gracefully — if your player struggles, use the SRT to TXT tool to strip them.
