Whisper Web supports every video format your browser can decode: MP4, MOV, WebM, AVI, and MKV. The audio track is extracted automatically — no manual conversion step required.

No. Whisper Web extracts the audio track from your video file automatically. Upload the video directly and transcription begins — no ffmpeg, no command line, no extra tools needed.

Yes. Use Whisper Web's built-in media downloader to download the video first, then transcribe it locally. Alternatively, paste a direct video/audio URL into the URL input field for supported sources.

With WebGPU acceleration, a 10-minute video typically transcribes in 1–3 minutes (3–5x faster than real-time). Without WebGPU, processing runs at roughly real-time speed. A 1-hour video takes approximately 15–20 minutes with WebGPU enabled.

Yes. Every transcript includes timestamps for each segment, which can be exported as JSON. For dedicated SRT/VTT subtitle files, use the Generate Captions tool on Whisper Web.
