About AIFF to MP4 Conversion
AIFF stores pristine uncompressed audio in Apple's legacy format, while MP4 (MPEG-4 Part 14) is the most universally supported media container in the world. Converting AIFF to MP4 compresses the audio to AAC and wraps it in a container that works everywhere — web browsers, smartphones, smart TVs, game consoles, car stereos, and every operating system. MP4 is the format the internet runs on.
Why Convert AIFF to MP4?
AIFF is effectively limited to Apple professional environments. MP4/AAC plays on every device ever made in the last 15 years. For web distribution, social media, mobile apps, or any cross-platform scenario, MP4 is the only format that guarantees universal compatibility. The HTML5 audio and video elements support MP4 natively in all browsers.
Common Use Cases
- Publishing AIFF studio recordings as web-ready MP4 audio for HTML5 streaming
- Distributing AIFF masters to a global audience across all devices and platforms
- Creating MP4 audio files for social media platforms that require MP4 input
- Embedding audio in web applications using the HTML5 audio element
