AAC to MP3 Converter

AAC (Advanced Audio Coding) is a modern audio codec developed as an improvement over MP3. Used by YouTube, Apple (iTunes, Apple Music), streaming services. More efficient than MP3 at the same file size.

Despite technical superiority, AAC isn't supported everywhere: some older players, car stereos, voice recorders only work with MP3. For maximum compatibility, convert to MP3.

Technically yes. AAC provides better quality at the same bitrate, especially at low ones (128 kbps and below). At high bitrates (256+ kbps), the difference is minimal and unnoticeable to most listeners.

AAC is more efficient than MP3, so to preserve quality choose a higher MP3 bitrate: AAC 128 kbps → MP3 192 kbps, AAC 192 kbps → MP3 256 kbps, AAC 256 kbps → MP3 320 kbps.

AAC and MP3 are both lossy formats. Conversion involves transcoding with minimal additional loss. Choose high bitrate to preserve quality.

AAC is a codec (compression algorithm). M4A is a container that usually contains AAC. It's like DivX and AVI: DivX is the codec, AVI is the container. The converter processes both variants.

YouTube (video audio track), iTunes Store, Apple Music, Spotify (for iOS), PlayStation, Nintendo Switch. It's the de facto standard for streaming audio on the internet.

If you have a separate AAC file — yes. To extract audio from video (MP4, MOV), use a dedicated audio extraction tool.

Yes. AAC metadata is transferred to MP3 ID3 tags. Title, artist, album and other information is preserved.

The service accepts files up to 100 MB. For AAC that's a lot — about 4-5 hours of music at standard quality.

Yes. All files are processed in an isolated environment and automatically deleted immediately after conversion. We don't store or share your files.

Yes. The service is optimized for mobile devices. Works in Safari on iPhone, Chrome on Android.
