About M4A
M4A
M4A is an audio-only MPEG-4 container, commonly used for audio tracks purchased from the iTunes Store. It typically wraps AAC or ALAC audio. M4A offers better quality than MP3 at similar bitrates and is natively supported by Apple devices and most modern media players.

Frequently Asked Questions
What is an M4A file?▼
M4A is an MP4 container holding AAC audio — Apple's standard for iTunes, iPhone voice memos, and Apple Music downloads (without DRM).
What is the difference between M4A and MP3?▼
M4A (AAC inside) sounds better at the same size and supports features like chapters, but MP3 plays on more legacy devices. For modern phones and apps, M4A is the better default.
Why can't my device play M4A files?▼
Some car systems, old players, and Windows apps lack M4A support. Converting to MP3 makes the file work everywhere.
Does converting M4A to MP3 lose quality?▼
A small amount — both are lossy, so avoid converting back and forth. For a one-time compatibility conversion, the result at high bitrate is indistinguishable for most listeners.
Can I batch convert iPhone voice memos?▼
Yes — drop all your M4A memos at once and convert them to MP3 privately in your browser. Nothing is uploaded.
