High quality is more accurate and uses a larger one-time download. Normal works well for clear speech; for some languages such as Chinese, High is noticeably better.

WAV Transcription

WAV (Waveform Audio File Format) provides uncompressed audio, which is ideal for speech recognition. This tool decodes your WAV file and processes it with the Whisper AI model running as WebAssembly in your browser. The transcript includes timestamps for each segment.

Features

Near-Zero CO₂

Server-based converters upload your file, process it remotely, and send it back — consuming network and data-centre energy on every request. WebConverter runs entirely on your device, so the only energy used is your local CPU. No data transfer, no server electricity.

Install for Offline Use

WebConverter works offline as a Progressive Web App. Click "Add to Home Screen" on mobile or the install button in your browser's address bar. Once installed, you can convert files without any internet connection.
