What Is Mp3tag?


Mp3tag is a feature-rich application designed to make managing your music library simpler and more efficient. Specifically designed to make complex tasks straightforward, Mp3tag provides a central point for all supported file formats and tag editing features in one convenient place.

Mp3tag supports flexible tagging by reading and writing user-defined field names in an organized way, making editing tasks part of workflows. This also enables editing tasks to be combined into action groups for ease of management.


Mp3tag is a versatile program for editing the metadata of audio files like MP3, Ogg, Flac and Wav. You can use Mp3tag for simple tagging tasks or more complex operations on large music libraries. Furthermore, this application supports multiple file formats and taggers simultaneously – providing efficient workflows when handling mixed-type libraries.

Mp3tag’s tagging functions have been designed to be as flexible and accommodating as possible in order to support a wide variety of use cases, but many users may have individual requirements that go beyond basic functionality. Therefore, multiple action groups have been created which enable you to tailor Mp3tag according to your own specific requirements – and more information on this matter is available within its documentation.

Tagging can be accomplished using the entry fields located in the Tag Panel on the left side of the main window. Once selected files lose focus (usually when switching them with mouse click or keyboard arrow key while still having focus), their changes are saved automatically in Mp3tag’s database when this happens; to prevent Mp3tag from saving these changes when it loses focus, turn off this option in Options – Tagging.

Edit – Customize allows you to create customized entries for the Tag Panel, using macros (text that expands when clicked upon) in each entry. For instance, an artist field could contain an entry that displays their current filename when they select one in the Tag Panel.

Additionally, you can create custom fields in the File Info dialog for storing, editing, and viewing file information. Furthermore, these fields allow you to assign special characters directly into tags of files which will then be replaced in output by their appropriate equivalent characters of your format.

Mp3tag allows for the easy tagging of WAV and FLAC files by writing Vorbis comments (as specified by ID3 specifications) as well as regular tags. Furthermore, its Converter feature lets you change tags according to templates in files you import or convert.


Mp3tag is an advanced and user-friendly tool for editing metadata of music files. It supports batch tag editing of ID3v1, ID3v2.3, ID3v2.4 iTunes MP4, WMA Vorbis Comments and APE Tags which cover most audio formats. In addition, Mp3tag also allows you to rename files based on tag information; replace characters or words within tags or filenames with other options; import/export tag data between computers; create playlists etc.

This software has the capacity to scan all of your music files for existing tag information and write new tags if necessary, helping to organize and correct incorrectly tagged files that may have come from other sources (for instance an internet radio station). Album art can also be added directly into each track or attached separately as separate jpg images – giving you control over whether its embedded in each track file or just appended as separate jpg images.

One of the key advantages of this software is its compatibility with various music file formats, so that it will read most tagging information correctly in most files – particularly useful if you own many FLAC files that do not always use ID3v2 tagging formats.

Mp3tag provides another convenient feature by exporting all current tag information for files or folders from within Mp3tag into iTunes, iSyncr and more – saving you time as you no longer have to manually update file information each time new music arrives or disappears from your computer.

Mp3tag also features an automated export feature to convert file information to text format for easy inclusion into other software such as databases or website pages, making this tool useful when updating a large number of files quickly and without taking time to go through them individually in the Mp3tag GUI.

Batch Editing

Though music files typically store their information within their audio data itself, many users also choose to add extra metadata tags that audio programs support – known as file metadata – which allow them to identify songs by artist, album track number and genre among other things.

Editing each file manually would be time-consuming and inconvenient; using Mp3tag’s batch editing features it is now possible to edit and save multiple tags simultaneously.

Files may be selected by clicking them directly, or using one of the keyboard shortcuts listed below. Each selection has its own keyboard shortcut that can be activated either by clicking its corresponding toolbar button, or pressing its respective key combination on your keyboard. Select all selects all files within a directory; these are highlighted yellow for easy identification, while unselect all removes this highlight altogether.

The Tag Panel is where most of the work for editing file metadata occurs, providing a customizable set of actions that can be applied to selected files – importing, exporting and renaming among them. To change which fields appear within it use View menu.

Mp3tag’s Batch Editing feature makes managing multiple files at once quick and effortless, enabling you to apply actions across a group or even create playlists which can be played back by Groove.

With Mp3tag, it is possible to import tag information from text-based files for correction or transfer between computers. Import can be done either using File > Import or the command line function Import.

Mp3tag provides the ability to export tag and file information as text-based files for archive or use in other applications, preserving both original and modified tag information in these exported files. Each export uses an Export configuration which outlines its format and content when exported; you can access them either through File > Export dialog or the Export List.


If you ripped CDs to create backup MP3 files but the original ripping program did not export all the relevant tags and album art correctly, retagging can be an arduous task. Mp3tag provides an effective solution that makes this task simpler: just try it for free now.

Discogs and MusicBrainz tracks are imported, along with any custom Tag Sources you enable, to an existing file using the Import From Tag Sources window. Furthermore, using its search window you can specify which fields from each Tag Source should be imported in what order – useful when working with collections that contain some inconsistently tagged files.

Mp3tag provides several different tagging formats and exports a CSV file which can be imported into another application such as iTunes. You can also set up templates in directories so Mp3tag automatically copies information into any new files in those directories – perfect if you’re organizing an online library and keeping everything streamlined!

When you’re ready to begin tagging files, simply select them and click on the Tagger menu item. From here you can choose between various tagging options – usually the defaults work just fine but feel free to customize to meet your preferences if necessary – as well as quick actions for tasks such as case conversion and text replacement that can be combined into workflows that apply in mass.

Export all of your tagging settings as a custom script for easy automation when retagging multiple files at once. Save this script as a reusable workflow so you don’t have to complete everything at once! Mp3tag supports many formats of export files including plain text, HTML and XML for additional convenience.
