What changes when SRT becomes WebVTT
Cue timing and text transfer cleanly in common cases. WebVTT uses its own header and syntax, so the output is rebuilt as a valid VTT file rather than renamed.

Questions about this tool
Can this generate subtitles from a video?
No. It converts an existing subtitle file. Use Extract Embedded Subtitles for a video that already contains text subtitle tracks; speech recognition is a different workflow.
Do my files or text leave this device?
Your source content is processed in this browser, not uploaded for processing. The browser may download a processing engine from Voice2Sub’s CDN. Those engine requests do not contain your source file.
Need subtitles created automatically from audio or video?Voice2Sub can transcribe spoken audio when you need a complete subtitle workflow instead of a file utility.
