VTT to SRT Converter

Local-first

Convert WebVTT subtitles to SRT locally for editors, caption tools, and subtitle sharing workflows.

How this tool actually works

The converter splits WebVTT into cue blocks, finds timeline rows, removes cue identifiers and timeline settings, changes decimal points to commas, and renumbers the result as SRT. It is intended for simple text cues, not lossless subtitle migration.

  • Renumber simple WebVTT cues
  • Convert timestamp separators to SRT
  • Remove WebVTT timeline settings

How to use it

  1. Paste WebVTT content beginning with WEBVTT.
  2. Convert and compare every start and end time.
  3. Review voice, class, ruby, positioning, and multiline cues manually.
  4. Test the SRT in the target player before delivery.

Quick example

Example input

WEBVTT

intro
00:00:01.000 --> 00:00:03.500 position:20%
Hello world

Expected result

1
00:00:01,000 --> 00:00:03,500
Hello world

Cue settings are removed, while advanced WebVTT markup is not translated into equivalent SRT styling.

Best use cases

  • Convert plain WebVTT dialogue for SRT-only players.
  • Renumber simple caption cues.
  • Prepare a draft for manual subtitle quality review.

References and scope

WebVTT supports cue settings and markup that SRT does not represent in the same way. This converter preserves basic timing and text only.

  • A cue is rejected when its end is not later than its start.
  • WebVTT styling and positioning semantics are not converted to SRT.
