SRT fixer and cleaner

An editor rejects your subtitle file? This renumbers cues, sorts them by time, removes empty ones, and fixes overlaps and zero-length timings. It runs in your browser.

FAQ

Why does my editor reject the SRT?

Common causes are missing or duplicate numbers, overlapping timings, end times before start times, and stray blank cues. This tool fixes all of these.

Will it change my words?

No. Only the numbering and timings change, and tags only if you tick the box.

Is my file uploaded?

No. It runs in your browser.
