YouTube Video to VTT: Extract Subtitles from a Video as WebVTT

Getting subtitles from a YouTube video as VTT means pulling out the subtitle track of one specific video in WebVTT format. VTT is the right format when you want the captions to render natively in a browser. This guide covers the workflow and the use cases for the resulting file.

Quick answer

1. Open YouTube Caption Downloader.
2. Paste the YouTube video URL.
3. Pick a subtitle track (manual preferred).
4. Choose VTT as the output format.
5. Click download.

You now have a VTT file with the subtitles from that specific video.

Why VTT

VTT (WebVTT) is the W3C standard for HTML5 video captions. It’s the right format when:

• Embedding captions in HTML5 <video> with <track>
• Building a web-based video player
• Serving captions from a CDN alongside video files
• Supporting accessibility compliance via the standard <track kind="captions"> semantic

For the format comparison with SRT and TXT, see SRT vs VTT vs TXT.

What you can do with the VTT

Embed in HTML5 video

The primary use case for VTT:

<video controls>
  <source src="video.mp4" type="video/mp4">
  <track kind="captions" src="captions.vtt" srclang="en" label="English" default>
</video>

Browsers render the VTT cues natively. No JavaScript needed.

Use in OBS or streaming

OBS accepts VTT for closed captions. Load it as a browser source or via a plugin.

Convert to SRT for editing

If you need to edit in a video editor:

ffmpeg -i captions.vtt captions.srt
