오디오를 텍스트로 변환 FAQ
What audio formats can I transcribe for free?
Common formats such as MP3, WAV, WebM, M4A, and more work in modern browsers. Drop a file or browse to upload — transcription runs locally with Whisper.
Is there a file size or length limit?
Very long files depend on your device memory and CPU. For best results, split extremely long recordings or use a smaller Whisper model with the quantized option enabled.
Do I need an account to transcribe audio?
No sign-up is required for this free browser tool. Open the page, add audio, and transcribe — no login for local transcription.
How is this different from cloud transcription services?
Cloud tools usually upload your audio to their servers. Whisper AI’s free tool runs the model in a Web Worker in your browser, so your file is not sent to us for transcription.
Is this transcription tool really free?
Yes. These pages are free to use with no paywall for local browser transcription. Optional paid plans apply to the Chrome extension and cloud features, not this on-page Whisper tool.
Is my audio private when I transcribe here?
For these free tools, speech-to-text runs locally in your browser. We do not upload your audio to our servers for transcription. URL mode fetches the file from the link you paste; that request goes from your browser to the host.
