SRT to VTT converter

How it works

Paste your SRT below or open the file, and the WebVTT version appears right away. It's free, needs no sign-up, and runs entirely in your browser, so nothing is uploaded.

SRT and VTT: what's the difference?

Both are plain-text subtitle formats with timed cues. SRT numbers each cue and uses a comma before the milliseconds, as in 00:00:01,000. WebVTT starts with a WEBVTT line and uses a period, as in 00:00:01.000. Browsers' HTML5 video players use VTT, while many editors and upload forms accept SRT.

What this converter changes

  • Adds the WEBVTT header.
  • Changes the timestamp format.
  • Removes the cue numbers, which VTT doesn't need.

Frequently asked questions

Is my file uploaded?

No. The conversion runs in your browser, and the file stays on your device.

Does converting change the timing?

No. The times stay the same, and only their format changes.
