Formats
M4A files
AAC audio in an MP4 container. Better quality than MP3 at the same size, and what Apple software produces.
Convert M4A to
Arazio converts M4A to seven formats. All of them sit on the ring.
Tools that work on M4A
Hold ⌥ over a M4A instead of ⇧ and these appear. They change the file without changing its format.
What it keeps
- Lossy — quality is traded for size, and converting repeatedly compounds the loss.
- Metadata — EXIF and similar fields are carried across, and the Strip Metadata tool can remove them.
Where the file goes
Beside the original, in the same folder, with the same name and a new extension. Nothing is overwritten and nothing is uploaded — see Privacy and permissions.
Extensions: .m4a · Category: audio · M4A converts to seven formats — hold ⇧ and they appear around the cursor.
