Convert MOV to M4A on Mac

How to convert MOV to M4A with FileFlip
Select the MOV files
In Finder or on the Desktop. One file, or a whole folder with ⌘ A.
Press ⌥ F
FileFlip opens next to the selection and lists the formats it can make from MOV. Type “M4A” to jump to it.
Choose M4A and press Return
The M4A files appear next to the originals with the same names. The MOV files stay as they are.
MOV and M4A
Screen recordings and iPhone videos are MOV files, which some websites, TVs and Windows apps handle less well than MP4. M4A with AAC gives small files that still sound good and play on Apple devices and most others.

Other ways on a Mac
For one file now and then you may not need FileFlip. These work with what’s already on your Mac.
QuickTime Player
Open the video in QuickTime Player and choose File → Export As → Audio Only. QuickTime saves the soundtrack as an .m4a file.
Good for one video at a time.
Terminal
macOS includes avconvert, which picks the file type from the extension you give the output.
avconvert --source clip.mov \
--preset PresetAppleM4A --output clip.m4aBuilt into macOS. Run avconvert --help for other presets.
