Frequently Asked Questions

What audio formats are supported?
Whisper Web supports every audio format your browser can decode: MP3, WAV, M4A, FLAC, OGG, WebM, and AAC. There is no format conversion step — drag and drop your file, and transcription begins immediately.
Is there a file size limit?
No. All processing runs on your device, so there are no server-imposed upload limits. Users regularly transcribe files over 500 MB and recordings lasting several hours without issue.
How accurate is the transcription?
OpenAI Whisper achieves a 4.2% word error rate on the LibriSpeech benchmark — comparable to professional human transcribers. On clear audio with minimal background noise, expect 95%+ accuracy. Using a larger model (Small or Medium) improves results on accented or noisy recordings.
Do I need to create an account?
No account, email, or signup is required. Open whisperweb.dev and start transcribing immediately. Your first transcription can begin within 30 seconds of opening the page.
Is my audio data safe?
Yes — audio never leaves your device. All transcription runs locally via WebGPU or WebAssembly in your browser. You can verify this by disconnecting from the internet after the page loads; transcription continues to work offline.
Can I transcribe audio in languages other than English?
Whisper supports 100+ languages, including Spanish, French, German, Japanese, Arabic, and Mandarin. Enable automatic language detection or manually select the source language for optimal accuracy.
