The formats explained
What is SRT? (SubRip)
The most widely supported subtitle format. Plain text with numbered cues and HH:MM:SS,mmm timecodes — it works in almost every video player, editor, and uploads straight to YouTube.
What is VTT? (WebVTT)
The W3C subtitle format required by HTML5 video and most web players. Like SRT but with a WEBVTT header and dot-separated milliseconds, plus optional styling and positioning cues.
Why convert SRT to VTT?
- VTT (WebVTT) is the only subtitle format HTML5 <video> and most web players can read — you need it to caption anything on a web page.
- Online course platforms, streaming dashboards and CMS uploads often only accept a .vtt file.
- You exported an SRT but your web player won't load it — convert to VTT and it just works, with the timing untouched.

What's the difference between SRT and VTT?
SRT is the most widely supported subtitle format (desktop players, editors and YouTube), while VTT (WebVTT) is the format HTML5 video and most web players require. The text and timing are identical — only the file syntax differs.

No. Timecodes are parsed and re-emitted exactly, so your subtitles stay perfectly in sync — only the format syntax changes.
