How to convert SRT to VTT
- Paste your SRT subtitles into the SRT source box, or choose a .srt file (UTF-8, up to 5 MiB) — conversion runs automatically.
- Edit the source any time to re-convert, or press Convert to retry on demand.
- Review the VTT result — the cue count and any warnings appear with the output.
- Download the .vtt file, or copy the text straight out of the result box.
What changes between SRT and WebVTT
SRT (SubRip) numbers every cue and writes timestamps with a comma, like 00:00:01,500. WebVTT — the web caption standard, usually saved as .vtt — writes the same moment as 00:00:01.500 with a dot, and the file must start with a WEBVTT header line. This converter rewrites the timestamps, adds the header, and preserves your cue timings and visible caption text. It exports plain captions: styling markup in the SRT (such as <i> or <font> tags) is stripped, and each removal is reported as a warning.
Frequently asked questions
Will my timings or caption text change?
Timings and visible caption text are preserved: timestamps switch from comma to dot decimals and a WEBVTT header is added. The output is plain caption text — any SRT styling tags (like italics or font color) are stripped and listed as warnings.
Why does HTML5 video need WebVTT instead of SRT?
The <track> element in browsers only accepts WebVTT (.vtt) files. SRT is widely used by editors and media players, but it is not a web standard.
Are my subtitles uploaded anywhere?
No. Parsing and conversion run entirely in your browser with JavaScript. Nothing is sent to a server, stored, or logged.
What files can I load?
A UTF-8 text file up to 5 MiB. You can also paste subtitle text directly into the source box instead of choosing a file.
