MP3 to M4A for Apple-first listeners, no upload

Some apps and pipelines simply want M4A: iOS audio tooling, certain audiobook and voice apps, templates built around AAC input. Feeding them an MP3 means converting, and converting between lossy formats always shaves a little more off. This page does it with care, 256 kbps AAC output to keep the shave minimal, and does it locally. If you have the original lossless source anywhere, encoding M4A from that is the better path.
Questions
Will this make my MP3 sound like AAC quality?
No. The M4A inherits the MP3's limitations and adds a small re-encoding cost. It fits AAC-shaped expectations; it does not upgrade audio.
When is this conversion actually right?
When software refuses MP3 input, or a device workflow standardises on M4A. Otherwise the MP3 serves as well.
Better options if I have the CD or FLAC?
Always encode from the lossless source instead; the FLAC to M4A page produces a strictly better file.
Uploaded?
Never. The conversion is in-browser.
