Frequently Asked Questions
Why choose M4A over MP3?
AAC compresses more efficiently than MP3 at the same bitrate, and it's the house format of Apple devices — iTunes ringtone workflows, Apple Books audio and some car systems specifically want .m4a files.
What bitrate does the M4A use?
192 kbps AAC — comfortably transparent for music converted from typical MP3 sources. The container is standard MPEG-4 audio, so it opens in iTunes/Music, QuickTime and on every Apple device.
Is it safe to convert music online?
Yes. Unlike traditional online converters, this tool never uploads your files. The conversion runs entirely inside your browser using WebAssembly, so music never leave your device — you can even disconnect from the internet after the page loads and it still works.
Is this converter really free?
Yes — completely free, with no sign-up, no watermarks, and no file-per-day limits. Because conversion happens on your own device, there are no server costs to pass on to you.
