Files never leave your device. Any size, any length.

WMA to MP3.
No size, no length limits.

WMA is Windows-only in practice; convert once to MP3 and forget about it.

WMA to MP3, without limits

In the cloud (next)

Windows Media audio files (ASF) usually carry WMA audio and come from Windows Media Player rips, old downloads. WMA is Windows-only in practice; convert once to MP3 and forget about it.

How it works

  • Drop the WMA file on this page (or choose it). Folders and many files at once are fine.
  • Browsers can’t decode this format, so it is converted in mp3fy’s cloud and deleted right after. This path arrives in the next release.
  • Live progress shows speed and time left; when it’s done, save the MP3 or download everything as a ZIP.

Frequently asked

Is my WMA file uploaded?

WMA can’t be decoded by browsers, so it’s converted in mp3fy’s cloud and deleted right after (cloud conversion arrives in the next release).

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.
