Frequently Asked Questions

What audio formats are supported?
Whisper Web supports any audio format your browser can decode — including MP3, WAV, M4A, FLAC, OGG, WebM, AAC, and more. If your browser can play it, we can transcribe it.
Is there a file size limit?
No server-side limit. Since processing happens on your device, the practical limit depends on your hardware. Most modern devices handle files up to several hours long.
How accurate is the transcription?
Whisper achieves near human-level accuracy on clear audio. Results depend on audio quality, background noise, and accents. Using a larger model (Small or Medium) improves accuracy for challenging audio.
Do I need to create an account?
No. Whisper Web requires no signup, no email, and no account. Open the page and start transcribing immediately.
Is my audio data safe?
Yes. Your audio is processed entirely in your browser. It is never uploaded to any server. You can verify this by disconnecting from the internet after the page loads — transcription still works.
Can I transcribe audio in languages other than English?
Yes. Whisper supports 100+ languages. Enable multilingual mode in settings and select the source language, or let the model auto-detect it.
