The conversion runs inside your browser with WebCodecs, the video engine built into modern browsers. That is why there is no upload, no queue and no file size limit set by us: only your device's memory limits it. Your file stays private.

Converter engine: [Mediabunny](https://mediabunny.dev) (MPL-2.0) on WebCodecs. MP3 encoding: [LAME](https://lame.sourceforge.io) (LGPL).

## How it works

1. **Drop or paste subtitles** An SRT or VTT file, or paste the text.
2. **Set the options** Output format, time shift in seconds or a frame-rate change.
3. **Save** Click Convert subtitles, then Save file.

## FAQ

**Are my subtitles uploaded?**
No. The text is converted in your browser.

**Is it free?**
Yes. No account and no limit.
