# AAC to MP3

ToolSugar converts .aac audio files to MP3 in your browser. Raw AAC often comes from radio captures, screen recorders and audio exports, and many apps cannot open it because it has no MP4 wrapper. MP3 is understood nearly everywhere. Nothing is uploaded. The first conversion downloads a 32 MB engine from a public CDN, and your device does the rest.

Runs on your device

## How it works

1. Select the .aac file.
2. Choose a bitrate at least as high as the original.
3. Press convert to MP3.
4. Download your MP3.

## Key facts

- **Tested with**: Raw AAC files with ADTS framing, the usual .aac layout.
- **Length**: Raw AAC has no duration field, so players may estimate its length. The MP3 reports its length properly.
- **Inside M4A?**: The M4A to MP3 page handles AAC in that wrapper.

## Common uses

- Fixing a recording that shows the wrong length or no length in a player.
- Using a radio capture in software that rejects raw AAC.
- Getting audio onto an older player with MP3 support only.

## Questions

### What is the difference between AAC and M4A?

AAC is the audio codec. M4A is a container that usually holds AAC. A .aac file is that audio with no container around it.

### Will it sound better as MP3?

No. Both are lossy, so MP3 is for compatibility, not for quality.
