How it works

  • Drop the M4R file on this page (or choose it). Folders and many files at once are fine.
  • The audio is decoded and encoded to MP3 right here in your browser — your file is never uploaded.
  • Live progress shows speed and time left; when it’s done, save the MP3 or download everything as a ZIP.

Frequently asked

Is my M4R file uploaded?

No. M4R files convert inside your browser; nothing leaves your device.

Is there a file size or duration limit?

No. mp3fy streams the file while converting, so a 20 GB recording or a 10‑hour lecture works the same as a short clip.

What bitrate should I pick?

192 kbps is the sweet spot for music and speech; 128 kbps for voice notes and podcasts; 320 kbps if you want the maximum. You can also keep stereo or down‑mix to mono.

Are my tags and cover art kept?

Yes — title, artist, album and embedded cover art are carried over into the MP3 when the source has them.
