About This Tool

AAC (Advanced Audio Coding) is the default audio format used by Apple devices and services. When you record a voice memo on your iPhone, download music from iTunes, or rip audio from Apple Music, the files are typically saved in AAC format. While AAC offers excellent audio quality with efficient compression, not all devices and software support it natively. Converting AAC to MP3 ensures your audio files play on virtually any device, media player, or platform — from older car stereos and portable music players to any computer or phone. All processing happens directly in your browser using WebAssembly technology for complete privacy.

Frequently Asked Questions

What is the AAC audio format?
AAC (Advanced Audio Coding) is an audio codec developed as the successor to MP3. It's the default format for Apple devices — iPhone voice memos, iTunes purchases, and Apple Music downloads all use AAC. It generally provides better sound quality than MP3 at the same bitrate.
Why should I convert AAC to MP3?
While AAC technically offers better compression than MP3, MP3 has universal compatibility. Some older devices, car stereos, and media players don't support AAC. Converting to MP3 ensures your audio works everywhere.
Will I lose quality converting AAC to MP3?
Converting between two lossy formats (AAC to MP3) does involve some quality loss, but at 320kbps the difference is negligible for most listeners. For critical audio work, keep your original AAC files as backups.
How do I convert iPhone voice memos to MP3?
iPhone voice memos are recorded in AAC format. Simply share the voice memo to your computer, then upload the .aac file here. Select your preferred quality and convert to MP3 for universal compatibility.
Is AAC better quality than MP3?
At the same bitrate, AAC generally provides slightly better quality than MP3. However, MP3 at 320kbps is excellent quality and offers the widest compatibility across all devices and platforms.
