About this format

Lossy compressed audio, created by the Fraunhofer Institute in 1993. It discards what the ear cannot hear and shrinks a file tenfold. The patents expired in 2017, so it is now entirely free. Opens everywhere.

What it can hold

  • Audio (lossy)
  • Title, artist, album art (ID3 tags)

What it cannot

  • Losslessness — quality drops a little each re-encode
  • Multichannel — stereo at most

When you convert it

MP3 → WAVQuality does not improve. What was discarded stays gone. Ten times the size.
MP3 → AACSlightly better quality at the same size. For Apple devices, go this way.
MP3 → FLACConverting to lossless does not restore what mp3 lost. Pointless.

When it will not open

  • Almost never
  • Corrupt ID3 tags show odd titles

In one line Never re-encode an mp3 into another mp3. If you have the original, start from that.

Frequently asked questions

How do I convert a MP3 file?

Drop the file into the window, pick the target format, and download the result. No account required.

Do I need to install anything?

No. It runs in your browser. A Windows installer is available separately if you prefer one.

What if the format I want isn't listed?

Every engine's capabilities are merged into a single graph, so unlisted pairs are chained automatically through intermediate formats along the least-lossy route.
