YouTube Subtitles to VTT: Download Subtitles as WebVTT Files

The shortest path from YouTube subtitles to a VTT file is a direct download with the VTT format selected. The downloader pulls the subtitle track and saves it as WebVTT directly. This guide covers the workflow and what to do with the resulting file.

Quick answer

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

You now have a VTT file.

Why VTT

VTT (WebVTT) is the W3C standard for HTML5 video captions. Every modern browser renders it natively with the <track> element. Use VTT when:

• Embedding captions in HTML5 <video>
• Building a web-based video player
• Serving captions from a CDN alongside video files

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

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

The browser:

• Renders captions natively
• Toggles on/off with the c keyboard shortcut (in most browsers)
• Supports styling cues defined in the VTT
• Auto-selects language based on user preference

Use in OBS

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

Serve from a CDN

For large-scale deployments, host VTT files alongside video files. Browsers fetch them via <track>.

VTT format details

A typical VTT file:

WEBVTT

1
00:00:01.000 --> 00:00:04.500
Welcome to the channel.

2
00:00:05.000 --> 00:00:09.200 align:center
Today we're talking about captions.

Three things to know:

• WEBVTT header. Required. Without it, the file won’t load.
• Dot in milliseconds. VTT uses . (00:00:01.000). SRT uses ,.
• Cue settings. Optional. Position with align:center, line:90%, etc.

For the full format breakdown, see SRT vs VTT vs TXT.

Convert from SRT to VTT

If you have an SRT and need VTT:

ffmpeg -i input.srt output.vtt

Or manually:

1. Add WEBVTT at the top of the file
2. Change commas to dots in timestamps

Track selection

For VTT extraction, pick:

• Manual track — uploaded by creator. Highest accuracy.
• Auto-generated track — produced by speech recognition. Variable accuracy.

For the accuracy deep-dive, see auto-generated captions explained.

Tips

• Use VTT for the web. SRT for editing, TXT for reading, VTT for HTML5.
• Verify the WEBVTT header. Without it, browsers won’t render captions.
• Test in the browser. Embed in a test page and verify rendering before deploying.
