M4A is AAC in Apple's favorite outfit: the audio-only MP4 your iPhone speaks natively. An MP4 container holding only audio: usually AAC, occasionally Apple's lossless ALAC.

What this M4A converter flips
Two directions, one page. Outbound: turn M4A into MP3, WAV, FLAC, AAC or any format a stubborn app insists on: useful because M4A is weak at older Windows software and stubborn car stereos that expect a .mp3. Inbound: turn practically any audio or video file into M4A, which earns its keep at sounding great anywhere in the Apple ecosystem.

Questions people ask
What can I convert M4A to?
Any of Flippy's 40+ output formats: MP3, WAV, FLAC, AAC, OGG and more, plus video containers if a platform insists on video.
Will I lose quality working with M4A here?
M4A is a lossy format, so re-encoding trims a little detail each time. Work from the best source you have and convert once: at sensible bitrates the difference stays inaudible.
Is this M4A converter really free?
Yes: free for everyday use with no daily cap, no signup, and your files delete themselves from our servers within an hour. Pro exists for heavy days: bigger files, whole folders at once.
