Video to SRT by InBrowserConvert turns a video file into a finished subtitle file without sending anything to a server. The Whisper speech recognition model runs entirely on your own device through WebGPU or WebAssembly, so the video and its audio never leave your browser. Drop in a video and the tool transcribes the speech and exports it as an SRT file with timings you can use in any player, editor, or platform. Because processing is local, there are no uploads to wait for, no account to create, and no daily limits to watch. That also makes it a genuinely private way to subtitle interviews, lectures, clips, and screen recordings that you would rather not hand to a cloud service. The same local approach powers the audio-to-text side of the tool, giving you a plain transcript alongside the timed subtitles. Everything runs in a modern browser, on desktop or mobile, and the tool is completely free. If you need captions for accessibility, a transcript for notes or search, or subtitles for a video you are publishing, Video to SRT handles the job in a few clicks while keeping your files exactly where they belong: on your device.
