Mp3tag for Mac

Hello, I’m Florian Heidenreich and I’ve just released Mp3tag for Mac to the Mac App Store. You can buy Mp3tag for Mac or check out the free 7-day trial.


Mp3tag is a powerful and easy-to-use tool to edit metadata of audio files. Musicians, DJs, podcasters, and audio-enthusiasts use it for many different aspects of handling audio files.

It supports batch tag-editing for multiple files at once, covering many audio formats from MP3, over MP4, and M4V (yes, that’s video!) to FLAC, OGG, OPUS, AIF, DSF, MPC, and WAV.

Furthermore, it supports online database lookups from Discogs and MusicBrainz, allowing to gather proper tags and download cover art for music libraries.

It offers renaming files based on the tag information, replacing characters or words in tags and filenames, importing tag information, and adjusting the size and image format of embedded cover art.

Since some of the tasks in managing a digital library are repetitive, Mp3tag allows for combining tasks into action groups, which serve as workflows for keeping consistency and order. Examples are formatting tag fields, performing case conversion, removing unwanted fields, or adjusting embedded cover art to match required sizes.
