Subtitle tools

One toolkit for subtitle files: convert between formats, fix timing, clean up hearing-impaired text, and merge or split files. Nothing is uploaded.

Pick the right fix

Wrong format for your player or website? Convert it: SRT to VTT for HTML5 video, VTT to SRT for desktop players, ASS to SRT for styled anime subtitles. Subtitles early or late by the same amount everywhere? Use the subtitle shifter. Fine at the start but worse by the end? That is drift: use two-point resync or the frame rate converter.

Every subtitle tool shares one editor

Each page opens the same toolkit with a different tab ready, so you can load a file once and combine fixes: convert, shift, clean, then export in any format. Every change can be undone, and you can preview the result over your own video without uploading it. Our guide to fixing out-of-sync subtitles explains which fix to use when.
