MOV files are already compressed, but M4A can compress further at a different bitrate. The size reduction is significant for sharing, uploading, and storage.
For email attachments, 128-192kbps works well. For music sharing, use 256-320kbps. AudioUtils lets you drop your file and convert instantly. No upload to a server, no waiting.
Both MOV and M4A are lossy formats. Each re-encode can degrade quality slightly. Convert once and keep the result. Choose the right bitrate for your use case. Higher bitrate means better quality but larger files.
Frequently Asked Questions
Why extract to M4A instead of MP3?
M4A using AAC delivers better quality than MP3 at the same bitrate and is the native format across Apple devices. If your MOV already contains AAC audio, extracting to M4A avoids re-encoding entirely.
Does this work with iPhone MOV recordings?
Yes. iPhone videos use MOV containers with AAC audio. This tool extracts just the audio track into an M4A file.
How long does extraction take?
Seconds. Everything runs locally in your browser using WebAssembly. No upload required.
