Convert SRT Subtitles to WebVTT Format Online

SubRip (.srt) and WebVTT (.vtt) are the two most popular subtitle file formats used on the web. While SRT is older and supported by almost all offline video players, WebVTT is the standard format for modern HTML5 web video players (like <video> tags, YouTube, Vimeo, and video players on iOS/Android).

SRT vs WebVTT: What's the Difference?

WebVTT is based on the SRT format but contains a few specific syntactic changes:

  • Header: WebVTT files must start with the string WEBVTT at the very beginning of the file.
  • Timestamp Separator: SRT uses a comma (,) to separate seconds and milliseconds (e.g. 00:01:20,500), while WebVTT uses a dot (.) (e.g. 00:01:20.500).
  • Styling Options: WebVTT supports advanced CSS styling, cue positioning, and alignments.

How to Convert SRT to VTT

  1. Copy the contents of your SRT subtitle file and paste it in the left editor box, or upload your `.srt` file.
  2. The converter will immediately adjust the timing format, add the required WebVTT header, and show the converted WebVTT code on the right.
  3. Download the file as a `.vtt` file, or copy the output directly.

Frequently Asked Questions

Why is WebVTT preferred for HTML5 web players?

WebVTT was designed by the W3C specifically for web browsers. It integrates directly with browser media elements, allowing easy subtitles toggle and rendering without third-party plugins.

Will my formatting tags survive the conversion?

Yes. Standard HTML tags like bold (<b>), italic (<i>), and underline (<u>) are fully supported in WebVTT and will be kept during conversion.

Are my subtitle scripts processed securely?

Yes. The entire conversion logic runs locally inside your browser sandbox. No subtitle data is sent to external cloud servers.
