How it works
Drag in your WAVs and we convert them to M4A automatically with high-quality AAC. For best results, keep the original sample rate (often 44.1 kHz), use 192 to 256 kbps for music or 96 to 128 kbps for voice, and set mono for mono sources; M4A tags like title and artist are preserved.
Privacy
Your audio is processed securely and used only to create your M4A files. We remove files from our servers after the conversion completes. No account is required, and we do not share your data.
