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.

## Key Features

- Bulk-Editing of Tags for multiple files at once.
- Editing of cover-art.
- Renaming files based on tags.
- Importing metadata from filenames.
- Assign track and disc numbers via the auto-numbering wizard.

That's right, while the MacOS version is new, I've been using MP3TAG for at least two decades. And it has always, always, always been the best. I'm a working DJ, and I obsess over the formatting of the names of my music files and keeping TAG info correct. There is no better app than this for a music library, I have searched every few months for about eight years now to see if it had been released for Mac. i'm such a dork, you wouldn't believe my excitement when I saw it finally has come to MacOS--and in true Florian form, it comes at a GREAT price so it's accessible for all (he did the WIndows version free for years with just askiing for donations...which I did several times). The UI is his classic interface that I've been using for years, it is remarkably fast (even with granting permissions), it is easy, it just works and works GREAT. Florian is a very accomplished app designer and developer. You will not go wroong with this utility. Thank you Florian for your years of dedication and Congratulations on your success on the Appstore. #10 in Music?! Whoot Whoot!

I highly recommend this app. If you are on the fence like I was, I'll get into that below. But first, the reasons why I now use this app daily. I'm a Deejay and its an ongoing process to develop a low-maintenance system for organizing a large and diverse collection, and most importantly, one that maximizes creativity and minimized management. This app was the missing piece, and fits perfectly into my flow. Particularly since I still buy vinyl, but rip it so I can listen to it when I'm not at my turntables.

Now if you are on the fence like I was, when I first downloaded the trial, here's what I would say. By just opening and clicking around the app, without digging into the documentation, I had a very surface level understaing of how deep this program was. I had the assumption that it lacked most of the features I wanted, like advanced batch editing, broad tag support, appending, substring replace, regex, etc. But there is little to no functionality that I have found missing so far now that I have spent some time learning the app. It can even be scripted.

I docked this one star only because I find some of the UI to be un-intuitive and take notes to remind myself how to do certain tasks. But that is not a reason to not buy this app if you need fine-grained control over tags in a large library.

Best Tagger Around!

I have used MP3Tag on Windows since it's inception, and purchased it eagerly when it was released for macOS. This app is fantastic. Florian is an indie developer and he is an incredibly nice guy and is very responsive to feedback, support questions, and feature requests. He is frequently adding new features that bring this closer to parity with the Windows version, and even a few that are unique to the Mac version. Best of all, he did a really great job making this a native Mac app and that looks and works like the standard conventions of macOS applications. When you see how clunky and ugly the Windows version is you'll realize what a big accomplishment he has has achieved with the polish of the Mac app.

Florian also a great community on the app's forums (where he is very active too) that have helped me resolve every eccentric music tagging and sorting need that I have had (which are MANY). If you're looking for a tagger, buy this app. Just do it. And support Florian—he seems like a great guy who deserves to do well.
