How to Change AAC to MP3 on Android
AAC is lossy audio that sounds better than MP3 at the same file size, but bare .aac files aren't accepted by every player, editor or site.. Drop your AAC below to save it as an MP3, trimming it on the waveform first if you want. It all happens on your Android phone.

AAC and MP3 in brief
- AAC is lossy audio that sounds better than MP3 at the same file size, but bare .aac files aren't accepted by every player, editor or site.
- MP3 is the audio format that plays on every phone, car stereo, speaker, editor and website. It's lossy, which keeps files small.
Android phone tips
- Once converted audio is in Downloads, music apps can see it. To make an MP3 your ringtone, add it under Settings › Sound › Ringtone › (+).
- Skipping a Play Store app means no extra permissions, no in-app ads and no storage used up.
- Decoding uses your browser's own audio support. If one browser can't open the file, try Chrome or Firefox.

Questions & answers
Will AAC to MP3 make it sound worse?
Very slightly, since MP3 is lossy, but at 192 kbps the difference is extremely hard to hear.
Can I trim the audio while I'm at it?
Yes. Drag the start and end handles on the waveform, play it back, and add a fade in or fade out if you like.
Do my recordings get sent anywhere?
No. Your browser does the conversion with your device's own processor, so your recordings stay with you. Once the page has loaded you could even switch off your internet connection.
Where do I find the converted file on my Android phone?
Tap Download. The file goes into your Download folder – open it from Files by Google or Chrome's downloads list.
