Subtitle Converter (SRT ↔ VTT)
Fix or repurpose any subtitle file in your browser: convert between SRT and WebVTT formats, shift all timings earlier or later to sync with audio, or strip timings to keep plain dialogue text.

Milliseconds work too: 0.5 = +500 ms.
Privacy note: Your subtitles stay on your device — nothing is uploaded. Conversion happens entirely in your browser.
How to use
- Upload an .srt or .vtt file, or paste the subtitle text directly.
- If subtitles are out of sync, enter a shift in seconds (negative = earlier) and press Apply Shift.
- Press Convert to VTT, Convert to SRT, or Dialogue Only for plain text.
- Download or copy the result.
Note: VTT styling cues and SRT position tags are simplified during conversion; timing and text are preserved. Timings never go below 00:00:00.
