Plays on everything
MP3 is the most widely supported audio format on earth — every phone, car stereo, browser and player reads it, unlike M4A which trips up some devices.
Private by default
Your audio is uploaded over HTTPS, converted on our EU servers, never shared, and permanently deleted within 1 hour.

Common questions

Why convert M4A to MP3?

M4A (Apple's AAC container) isn't supported by every device or app — some car stereos, old players and editing tools reject it. MP3 plays literally everywhere, which makes it the safest format to share.

Will I lose audio quality?

Both M4A and MP3 are lossy, so converting re-compresses the audio. Formatly uses a high bitrate so the result is indistinguishable from the original to most ears. For a perfectly lossless copy, convert to FLAC or WAV instead.

Does this work with iPhone voice memos?

Yes — iPhone Voice Memos export as .m4a, and this tool converts them straight to MP3 so you can use them in any app or editor.

Is there a file size limit?

Free users can convert M4A files up to 25 MB without an account, or up to 10 conversions per day with a free account. Pro users get 500 MB per file and 3,000 credits a month.
