M4A (.m4a) · Max 20 MB
Gmail, Outlook, and Yahoo all cap attachments at 25MB. A long M4A file can exceed that easily. Converting to MP3 at 128kbps keeps file sizes well under the limit.
For voice recordings and meetings, 128kbps mono is plenty. For music, 192kbps stereo sounds great and stays small. AudioUtils converts in your browser — no upload needed, no file touching anyone's server.
Drop your file, convert, download, attach. The whole process takes seconds. No signup, no email address required, no watermarks.
Frequently Asked Questions
Why can't I play my M4A files on Windows/Android?
While many modern apps support M4A, some older devices and software don't. Converting to MP3 guarantees playback everywhere.
Will I lose quality converting M4A to MP3?
Slightly. Both are lossy formats, and transcoding between them involves re-encoding. At 320kbps MP3, the difference is negligible for most listeners.
Can I convert DRM-protected M4A files?
No. Files purchased from iTunes with DRM protection can't be converted by third-party tools. Apple Music downloads with DRM are also not supported.
What about M4A files from Voice Memos?
Yes! iPhone Voice Memos save as M4A. This converter handles them perfectly. Great for converting voice recordings to a more shareable format.
