SRT to VTT
Turn SubRip subtitles files into WebVTT subtitles files on your own Mac, Windows or Linux computer. Asteria is free, works offline, and never uploads your files.
How to do it
- Download Asteria and open it. It's free and needs no account.
- Drop your SRT files onto its window, or press ⌘O (Ctrl O on Windows) to choose them. Drop as many as you like.
- Type srt to vttand pick Convert to VTT. Save subtitles as WebVTT for web video.
- Press ⌘↵ (Ctrl ↵ on Windows) to save. The VTT files appear next to the originals, which stay exactly as they were.
What it needs
Nothing. This conversion is built into Asteria, so it works the moment the app is open, even offline.
How it was tested
A real SRT file was converted on macOS on Apple silicon and Linux, and the VTT that came out was opened and checked with UTF-8 text to make sure it is what it says it is.
