Which subtitle formats can I convert between?

The GoChronos Subtitle Converter reads and writes SRT, VTT (WebVTT) and SBV (YouTube), reads ASS/SubStation Alpha, and can produce a clean plain-text transcript. Plain text can also be turned into estimated-timing subtitles.

How do I fix out-of-sync subtitles?

Use the Fix timing mode to shift every cue earlier or later by a number of seconds, or rescale timing by a percentage to correct frame-rate drift (for example 25 fps subtitles played at 23.976 fps).

Does it work without uploading my file?

Yes. Subtitle conversion is pure text processing that runs entirely in your browser — nothing is uploaded.

Is the Subtitle Converter free?

Yes. Free on GoChronos, works offline.
