Free Subtitle Converter — paste subtitles or drop a file and convert between SRT, VTT and ASS locally. Free and private.
Which conversions are supported? +
This tool parses SRT, VTT and ASS/SSA (Dialogue lines, override tags stripped, \N → newline) and renders clean SRT or VTT with renumbered cues.
What about styling and positions? +
ASS styling, VTT voice spans and cue settings are normalized to plain timed text so the output plays everywhere.
Is my file private? +
Yes. Files are read with FileReader and converted in your browser. Nothing is uploaded.
