MOV QuickTime Movie
MOV is Apple's QuickTime container and the format iPhones and many cameras record to. It often holds HEVC or ProRes video, which keeps quality high but files large.
MOV converterAAC Advanced Audio Coding
AAC is the successor to MP3 and the audio codec inside most MP4 videos, YouTube and Apple Music. A raw .aac file is an ADTS stream without a container.

Why convert MOV to AAC?
MOV files come from iPhones, QuickTime screen recordings on a Mac, and many cameras. Windows players, Android and many websites handle MOV inconsistently. Choose AAC when a player, hardware device or editor expects a raw AAC stream.
Audio extraction options
Only the audio track of the MOV is processed, so this is much faster than a video conversion. Choose the bitrate or quality, optionally trim to a start and end time, and download the AAC.
Frequently asked questions
Will the AAC lose quality?
Both formats are lossy, so converting re-encodes the data once more. Using a high quality setting keeps the generational loss very small. Avoid converting the same file back and forth repeatedly.
How big will the AAC file be?
About 1.4 MB per minute of audio at the default 192 kbps, so a 10-minute MOV gives roughly 14.4 MB. The size of the video track does not matter, because only the sound is kept. Choose 128 kbps for speech to make it about a third smaller.
