How It Works
Pick Your File
Select the AAC you'd like to convert. It never leaves your device at any point in the process.
On-Device Encoding
Your browser decodes the audio and re-encodes it as MP3. Most browsers handle this almost instantly — either way, nothing is sent to a server.
Save Your File
Download your new MP3 file — ready for phones, apps, players, or streaming.
Common Questions
No. The entire conversion happens locally in your browser tab. Your file never leaves your device or touches our server.
Some quality change is unavoidable when moving between two lossy formats, but we encode at a high bitrate so the difference is minimal for normal listening.
Files up to 100MB are supported. Larger files simply take a little longer, since everything is processed on your own device.
Any modern browser — Chrome, Firefox, Safari, or Edge. No plugins, extensions, or accounts are required.
Right now the tool handles one file at a time. Convert your files one after another, and each download is ready in seconds.
AAC and MP3 compress audio in different ways, so your browser first decodes the AAC back into raw audio, then re-encodes that audio as MP3.
