About MOV and AIFF
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.
AIFF is Apple's uncompressed audio format — the same raw PCM as WAV in a different wrapper, dating back to 1988. It is still the native interchange format for Logic Pro and much of the Mac production world, and converts to WAV with zero quality change.
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.
