Subtitle Format Converter

Convert between SRT and WebVTT in either direction. The source format is detected automatically from the content, not the filename.

Local processing only. Conversion happens on your device.

How it works

The tool inspects the source content and detects whether it is SubRip or WebVTT. It then converts to the other format, or to the specific target you select. All cue text and timings are preserved exactly.

Format notes

  • SRT uses comma-separated milliseconds: 00:00:05,000.
  • WebVTT uses period-separated milliseconds: 00:00:05.000 and starts with a WEBVTT header.
  • WebVTT cue settings are dropped when converting to SRT.
