MP3 to AAC Converter
Convert MP3 audio to AAC without uploading the file.
To convert MP3 to AAC, drop the file in and pick a bitrate. AAC is the successor to MP3 and sounds better at the same bitrate. It is what Apple Music, YouTube and most streaming uses. The conversion runs through FFmpeg in WebAssembly inside your browser, so recordings, interviews and unreleased music never touch a server.

AAC is the successor to MP3 and sounds better at the same bitrate. It is what Apple Music, YouTube and most streaming uses. Converting from MP3, which is already lossy, cannot restore what its encoder discarded — a second lossy encode only ever removes more.
