SBV (SubViewer) is the caption format YouTube Studio exports when you download captions from a video. Each cue is a comma-separated start and end timestamp followed by plain caption text, with no cue numbers and no styling.

Why convert SBV to SRT?

SRT is supported by nearly every video player and editor — VLC, Premiere Pro, DaVinci Resolve, Final Cut — while SBV is mostly limited to YouTube. Converting to SRT lets you reuse your YouTube captions anywhere, including translation workflows.

Is my caption file uploaded to a server?

No. The conversion runs entirely in your browser with JavaScript. Your file never leaves your device, and no account or signup is required.
