FAQ
Frequently asked questions
Why won't my M4A file convert?
Songs bought on iTunes before 2009 may be DRM-protected (.m4p) and can't be decoded by any browser. Apple Lossless (ALAC) M4A files may only decode in Safari.
Is M4A better than MP3?
AAC in an M4A file sounds slightly better than MP3 at the same bitrate, but MP3 is supported by more devices and websites. Convert when you need compatibility.
Can I convert WhatsApp or Telegram voice messages?
M4A voice notes work directly. Opus (.ogg or .opus) voice messages can be converted too — just drop them in.
Is it free and private?
Yes. There's no sign-up or limit, and your files are converted on your own device, never uploaded.
