FFmpeg: Removing Metadata Tags (excluding 'album' and 'cover image') from MP3 files

FFmpeg: Removing Metadata Tags (Excluding Album Cover Image) from MP3 Files

Metadata tags in MP3 files can be useful for storing information about the audio file, such as the title, artist, album, and track number. However, there may be situations where you want to remove certain metadata tags while keeping others. In this article, we will focus on using FFmpeg to remove metadata tags from MP3 files, excluding the album cover image.

What is FFmpeg?

FFmpeg is a free and open-source software project that produces libraries and programs for handling multimedia data. It is a powerful tool that can be used for a variety of tasks, including converting audio and video formats, streaming media, and manipulating metadata tags.

Removing Metadata Tags with FFmpeg

To remove metadata tags from an MP3 file using FFmpeg, you can use the following command:

This command tells FFmpeg to read the input.mp3 file, discard all metadata tags, and write the output to output.mp3. However, this will also remove the album cover image, which we want to keep. To exclude the album cover image, we can use the -map_metadata option with the -1 argument for the metadata tag we want to remove, and the -c option with the copy argument for the metadata tag we want to keep.

In our case, we want to remove all metadata tags except for the album cover image. The album cover image is stored in the covr metadata tag. Therefore, we can use the following command:

This command tells FFmpeg to read the input.mp3 file, copy the video stream (which includes the album cover image) using the -c:v copy option, copy the audio stream using the -c:a copy option, and discard all metadata tags except for the covr tag using the -map_metadata 0 and -map_metadata -1:g:0 options.

What if I Want to Remove Specific Metadata Tags?

If you want to remove specific metadata tags while keeping others, you can use the -map_metadata option with the -1 argument for the metadata tags you want to remove. For example, if you want to remove the TIT2 (title) and TPE1 (artist) metadata tags, you can use the following command:

This command tells FFmpeg to read the input.mp3 file, copy the video stream and audio stream using the -c:v copy and -c:a copy options, discard the TIT2 and TPE1 metadata tags using the -map_metadata -1:g:1 and -map_metadata -1:g:2 options, and keep all other metadata tags using the -map_metadata 0 and -map_metadata -1:g:0 options.

FFmpeg is a powerful tool for manipulating metadata tags in MP3 files. By using the -map_metadata option with the -1 argument for the metadata tags you want to remove, and the -c option with the copy argument for the metadata tags you want to keep, you can easily remove specific metadata tags while keeping others. In this article, we have covered how to remove all metadata tags except for the album cover image, and how to remove specific metadata tags while keeping others.
