About converting WAV to M4A
Going from WAV to M4A takes a couple of clicks: drop the file in, download the result. Drop in your WAV file (a .wav) and download a ready-to-use M4A file (a .m4a) — no software to install, no account to create, and no watermark on the output.
What is WAV?
WAV is uncompressed, lossless audio. Quality is perfect and files are large, making WAV ideal for editing and mastering rather than distribution.
What is M4A?
M4A is an MP4 container holding AAC audio — small, high quality, and the standard for Apple Music and voice memos.
Why convert WAV to M4A?
The usual reason to convert WAV to M4A is file size or quality: M4A fits the job better, whether that means a smaller download, a cleaner edit, or broader support. Audio is processed with ffmpeg using high-quality encoders (LAME, libopus, libvorbis, FLAC and more), so you get the best possible result for the destination format.
WAV vs M4A: what changes
M4A is lossy, so expect a much smaller file than WAV — usually at a cost in fidelity small enough to be invisible at normal viewing sizes.
When you'd convert WAV to M4A
You might be optimising images for a faster-loading page, exporting for a specific app or marketplace, or just making sure a colleague on a different device can open what you send.
Is it private?
Privacy is the default here. Your WAV file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
