SRT or VTT?
Use VTT for web players (HTML5 <track>) and SRT almost everywhere else. The timings and text are identical; only the wrapper changes. So an SRT you exported from a desktop editor becomes a VTT an HTML5 player can read, with nothing else touched. For the finer points, see our guide to SRT vs VTT subtitle formats.
Why it’s free
Subtitle files often hold sensitive transcripts, and this tool never sees them: the conversion runs on your device, so we store nothing and run no servers for it. That’s the reason it stays free.
Need captions from audio?
This tool converts files you already have. If you need captions made from a recording instead, the subtitle generator produces SRT or VTT with timings straight from the audio or video. The first 30 minutes are on the house.
Frequently asked questions
Does my file upload?
No. The file is converted in your browser and never leaves your device.
Is it free?
Yes, free to use with no signup and no limits.
What's the difference between SRT and VTT?
Both are subtitle files; VTT (WebVTT) is the web-standard used by HTML5 video, while SRT is the most widely supported elsewhere. The text and timings are the same.
Can you make captions from my audio?
Yes, that's transcription. Use the subtitle generator to create them from a video or audio file, with 30 free minutes to start.
