Sync subtitle timings

Upload a correctly-timed subtitle file, then re-time your other subtitle files to match it. Free, and no account needed.

The subtitle file with the timings you want. SRT, WebVTT, ASS/SSA, TTML, SBV, STL, CAP or Avid TXT — up to 5 MB.
Up to 10 files, up to 5 MB each. Each one keeps its own text and format — only the timings change. Formats can differ from the source.
Each file must have the same number of subtitles as the source, and its lines must line up one-for-one (subtitle 1 with subtitle 1, and so on). Files with a different count can't be synced.
