About AAC files

AAC (Advanced Audio Coding) is a highly efficient audio compression format developed by Fraunhofer IIS, AT&T, Dolby, and others. It delivers better sound quality than MP3 at similar bitrates, making it ideal for music streaming, podcasts, and mobile devices. AAC is the default audio format for Apple products (iTunes, iPods, iPhones) and is widely supported across platforms. Its lossy compression reduces file sizes significantly while maintaining excellent audio fidelity, though it's not as universally compatible as MP3.

With this SoConvert tool, you can convert multiple AAC files to AAC directly in your browser for free. You can also adjust the audio Bitrate during conversion.

Click the Options button in the top-right corner to open the settings panel, where you can customize the output AAC audio Bitrate.

Other Settings Explained:
