Extract WAV Audio from MOV

About MOV and WAV

MOV is Apple's QuickTime container, the default for iPhone recordings and screen captures on macOS. The audio track inside is usually AAC, which converts cleanly to anything here.

WAV is uncompressed PCM audio — the raw samples with a small header. It is the standard interchange format for recording, sampling and production work, at the cost of roughly 10 MB per minute of stereo.

Extracting audio from MOV re-encodes only the audio track — the video is discarded, so even long files finish quickly.

How the conversion works

This tool runs FFmpeg — the same engine behind most media software — compiled to WebAssembly, entirely in the browser. The file is read locally, converted locally and saved straight from memory; nothing is ever uploaded, which also means no queues and no server-side file size limits.

The converter itself is a one-time ~31 MB download on the first conversion, cached by the browser afterwards. Once it is loaded, everything works offline.
