Convert SRT to VTT online
Convert SRT to WebVTT because that is the only subtitle format an HTML <track> element reads. The change is small — a WEBVTT header line is added and the timestamp separator changes from a comma to a full stop — and the cue text is untouched.
When should you convert SRT to VTT?
- Add captions to a video on your own website
- Meet the requirement of an HTML5 player or a video library
- Prepare subtitles for a browser-based streaming setup
- Convert a downloaded subtitle file for web playback
Before you convert
Nothing is lost
SRT and VTT describe the same thing — timed cues. The timings and line breaks are carried across exactly; only the file's syntax changes.
VTT can do more
WebVTT also supports positioning and CSS-style cue settings. Converting from SRT does not add those, but the format leaves room for them.
What happens to your file
The SRT file is parsed into cues — a start time, an end time, and the text between them — and rewritten in VTT syntax. It is a text transformation, so it finishes almost instantly regardless of how long the video is.
Settings this conversion runs with
| Unit | Timed cue (start, end, text) |
|---|---|
| Timings | Preserved exactly |
| Styling | Not supported by the target |
What changes
- WebVTT is what browsers read from a <track> element. The timing format changes from comma to dot separators and a WEBVTT header is added — the lines themselves are untouched.
