Convert SRT subtitles to WebVTT format instantly — free, browser-only, timing preserved exactly.

About SRT to VTT Converter

SRT (SubRip Text) and WebVTT (VTT) are the two most common subtitle formats. SRT is the standard for desktop video players and most video editors; WebVTT is required by HTML5 <track> elements and is preferred by YouTube, Vimeo, and modern streaming platforms. The AT USE SRT to VTT Converter rewrites every cue with the comma-separated SRT timestamp format converted to the dot-separated WebVTT format, prepends the required WEBVTT header, and preserves all text content exactly. Everything runs locally in your browser — your subtitle files never leave your device.

Common use cases

  • Convert SRT subtitles to VTT for use with HTML5 <track> elements.
  • Upload VTT captions to YouTube or Vimeo from an SRT source.
  • Prepare SRT subtitles for a web video player that requires WebVTT.

How to use it

  1. Drop your SRT file into the converter or paste the subtitle text.
  2. Confirm the source format is set to SRT (pre-selected automatically).
  3. Click "Convert" and check the preview.
  4. Click "Download" to save the converted VTT file.

Frequently asked questions

Is this tool free?

Yes. Completely free, no login, no watermark, no signup. Everything runs in your browser.

What is the difference between SRT and VTT?

SRT uses comma-separated timestamps (00:00:01,000 --> 00:00:04,500) and is the most widely supported format for desktop players. WebVTT uses dot-separated timestamps (00:00:01.000 --> 00:00:04.500), adds a WEBVTT header, and is the standard for HTML5 video and most streaming platforms.

Will timing be preserved exactly?

Yes. The converter rewrites only the timestamp separator (comma → dot) and adds the VTT header. No timing data is altered or rounded.

Does my subtitle file upload to a server?

No. Conversion runs entirely in your browser — your file never leaves your device.
