Positive delays the subtitles (use if they appear too early); negative advances them (if they lag the audio).

💡 Fixes subtitles that are out of sync — shift everything earlier or later, and correct frame-rate mismatches with the speed factor. The format is detected and preserved. Everything runs in your browser.

Как это работает

When subtitles run ahead of or behind the audio, you just need to shift their timing. This re-times every cue in your browser, keeping the file format intact.

  1. 1
    You paste or drop a subtitle file
    SRT, VTT, SBV, LRC, or ASS — the format is detected automatically. Nothing is uploaded.
  2. 2
    You set a time shift
    Enter seconds (positive to delay, negative to advance) or use the quick presets. A speed factor also corrects frame-rate mismatches (e.g. 23.976↔25 fps).
  3. 3
    Every cue is re-timed
    Each cue's start and end are adjusted by the offset (and factor), clamped so nothing goes negative.
  4. 4
    You download the synced file
    The result is written back in the same format, ready to use.

Subtitles can contain unreleased dialogue. The re-timing runs entirely on your device — your captions are never uploaded.
