About AAC to MP3 Converter
Transcode, downsample, or convert local audio files between varying extensions in bulk.
100% Free & Absolute Privacy
Unlike other converters that upload your audio to a server, this tool uses WebAssembly to run a full version of FFmpeg directly inside your web browser. This means your files never leave your device. Because there are no server costs, this tool is 100% free to use, with no size limits and absolute data privacy.
