Switch From Apple's AAC to the Most Compatible Format
AAC is the default audio format for Apple Music, iTunes purchases, and iPhone voice recordings. While it is technically superior to MP3, compatibility gaps remain with older devices and certain software. Convert to MP3 when you need a file that absolutely every device and application on the planet can handle.
Why Convert AAC to MP3?
Legacy audio hardware like older car stereos, portable CD/MP3 players, and basic Bluetooth devices only recognize MP3 files.
Some DJ software, karaoke machines, and public address systems accept only MP3 input — AAC support is not guaranteed.
Cross-platform sharing is smoother with MP3 — Android users with non-standard music apps sometimes cannot play AAC files.
Website audio embedding works more reliably with MP3 since it has broader fallback support across all browsers including older versions.

How to Convert AAC to MP3
Add your AAC audio
Upload the AAC file from your Apple Music library, iPhone voice memo, or any other source. Both raw .aac and M4A-wrapped AAC are supported.
Transcode to MP3
The AAC stream is decoded and re-encoded to MP3. We recommend using a slightly higher bitrate than the AAC source to compensate for the lossy-to-lossy transition.
Enjoy total compatibility
Download your MP3 and use it anywhere. It will play on every piece of audio hardware ever made, without exception.
Frequently Asked Questions
Does converting AAC to MP3 reduce quality noticeably?
expand_more
Going from one lossy format to another does involve generational loss. At 256 kbps MP3 and above, the degradation is minimal and inaudible to most listeners. For critical listening material, consider converting from a lossless source instead.
Can I convert DRM-protected iTunes purchases to MP3?
expand_more
No. DRM-protected files (purchased from iTunes before 2009) are encrypted and cannot be converted. However, all iTunes Plus purchases since 2009 are DRM-free AAC and convert without issues.
My file is actually .m4a, not .aac — can I still use this converter?
expand_more
Yes. M4A is simply an MP4 container holding AAC audio. We detect this automatically. You can also use our dedicated M4A to MP3 converter for the same result.
Should I use the same bitrate as the AAC source?
expand_more
Go slightly higher. If your AAC is 192 kbps, encode the MP3 at 256 kbps to compensate for the less efficient MP3 codec. This way you avoid accumulating noticeable artifacts.
Pro Tips for AAC to MP3 Conversion
Bump the MP3 bitrate up one step from the AAC source — 128 kbps AAC to 192 kbps MP3, or 192 kbps AAC to 256 kbps MP3.
For iPhone voice memos (which record in AAC), 128 kbps MP3 is plenty since the source material is speech.
If you are converting your entire Apple Music library, consider whether ALAC (Apple Lossless) masters are available to start from instead.
