Audio Transcription uses a quantized ONNX export of OpenAI's Whisper model running entirely in your browser via WebGPU (Chrome 113+) or WebAssembly fallback — no audio file ever leaves your device. Choose between the Fast (tiny.en, ~75 MB, English-only) or Accurate (base, ~145 MB, multilingual) model. Upload MP3, WAV, M4A, WebM, or OGG files, or record directly from your microphone. Audio is decoded and resampled to 16 kHz mono using the Web Audio API before inference. Output includes an editable full-text transcript and an SRT subtitle file with word-level timestamps. Ideal for transcribing interviews, meeting recordings, lectures, podcasts, and voice memos without sharing sensitive audio with cloud services.

Simply input your data into the fields above. Our Audio Transcription will process your information instantly. You can then copy the results or export them depending on the specific tool features like Whisper tiny.en / base or WebGPU Acceleration.
