About M4A
M4A is AAC audio in an MP4 container and is the default on Apple devices. It sounds better than MP3 at the same bitrate, but some devices and software still do not support it.
M4A to MP3 is a lossy-to-lossy conversion, so there is a slight loss. Using the same or a slightly higher bitrate than the source keeps it minimal.
Frequently asked questions
My voice memo will not open on Windows
Convert it to MP3 and it plays in the default Windows player. Just drop the .m4a here.
Which bitrate should I use?
Voice memos are recorded at around 64 kbps, so 128 kbps is plenty. Use 192 kbps or more for music.
Can I convert protected Apple Music tracks?
No. DRM-protected files (.m4p) cannot be decoded.
Can I convert several files at once?
Yes. Add them all and run; they are processed in turn and can be saved as a ZIP.
Help us improve the service
If a conversion fails, sending us the circumstances helps us track down the cause. Knowing which devices and formats fail most often, and how long processing takes, lets us revise the supported formats and fix the bugs behind them. If you don't mind, leaving this on is a real help.
What is sent
The tool you used and the settings you chose (output format, quality, etc.), your device specs (GPU, memory, core count), the input format with a rough size, how many files succeeded or failed and how long it took, and the error type and details when something fails.
What is never sent
The files themselves, file names, text, subtitles or prompts you add to a video, and IP addresses. The data goes only to this site's own server, never to a third-party service.
