The MP3 is decoded and re-encoded as AAC, written out as a raw ADTS stream. Both formats are lossy, so this transcode trades a small amount of quality for compatibility with whatever needs the AAC input.
This makes sense when a broadcast tool, HLS packager, or device pipeline specifically wants .aac. For general listening, converting MP3 to AAC gains you nothing audible.
Raw .aac files have no standard tag support, so titles and cover art from the MP3 will not carry into the stream. If you want AAC audio with metadata intact, convert to M4A instead: same codec, friendlier container.
