About WAV to M4A

Convert uncompressed WAV files into M4A, the AAC-based format that fits neatly into iTunes, Apple Music, and iOS while shrinking large WAV recordings. Choose a bitrate and we encode AAC into an M4A container locally.

The conversion runs entirely in your browser via WebAssembly. Your WAV never leaves your device and nothing is uploaded.
