M4A is the container Apple uses for AAC audio. Same codec as AAC, just in a different wrapper. iTunes, Apple Music, and all Apple devices use M4A by default.

Is there a file size limit?

There's no hard limit, but very large files (over 2 GB total) may be slow or run into browser memory constraints.
