- MP3 is universally supported across smartphones, tablets, media players, and web platforms, ensuring better accessibility.
- Smaller MP3 file sizes allow for faster uploads, quicker downloads, and smoother playback on all devices.
- MP3 is better suited for streaming and mobile use due to its lightweight and compressed nature.
- At higher bitrates, MP3 maintains excellent sound quality that is indistinguishable from AIFF for most listeners.
