Why convert WAV to M4A?
A 4-minute WAV recording can weigh 40 MB or more — too big for iTunes libraries or sharing. Converting to M4A shrinks it dramatically while fitting natively into Apple Music, iTunes and CarPlay.
WAV vs M4A at a glance
WAV is the lossless audio standard — uncompressed PCM audio, identical quality every time, but files are 10× larger than MP3. M4A is AAC audio in an MPEG-4 container — the format used by iTunes and Apple Music, same quality as AAC with slightly better metadata support.

WAV to M4A — frequently asked questions
Is this WAV to M4A converter really free?
Yes — completely free, with no sign-up, no watermarks and no daily limits.
Will I lose quality converting to M4A?
M4A uses lossy compression, so the image is re-encoded at high quality (92%). For photos the difference is practically invisible; for text-heavy graphics or logos, a lossless format like PNG preserves sharp edges better.
Is the conversion private?
Audio conversion runs on our servers with ffmpeg — your file is deleted immediately and never stored.
