Tools
A subtitle converter that runs in your browser
Small tools for files you already have. Each one converts locally in the browser tab, so the file is never uploaded.
SRT to VTT converter
Drop in an .srt or a .vtt and get the other format back. The conversion happens in this browser tab, so the subtitle file never leaves your computer.
SRT to text converter
Turn an .srt or .vtt into plain text with the cue numbers and timings removed. Runs in this browser tab, so the file stays on your computer.
Why these run in the browser
Converting a subtitle file does not need a server. The work is parsing a few hundred lines of text and writing them back in a different shape, which any browser does instantly. Most online converters upload your file anyway, because an upload is how they put an advert in front of you or a limit on your free tier.
These do not. The conversion happens in the page you are reading, and there is no upload endpoint to send a file to. That is also the honest boundary of our desktop app: SnailText generates subtitles from audio and cannot convert between existing subtitle formats, so these tools fill a gap the app does not cover rather than advertising something it does.
