When this is useful

Recordings from equipment and apps

Some recorders save as AAC; MP3 opens anywhere.

Standardize a folder of audio files

Tips for a good result

  • For files in M4A (AAC inside MP4), the M4A to MP3 page is the most suitable.
  • Use 192k or more for music.

What this tool does not do

  • Both formats compress with losses: the conversion reduces the quality a little.
  • The new file carries the “WebFaz.com” credit in the metadata (comment and artist).

Frequently asked questions
