How to Add Cover Art to MP3 Metadataby Seamus Islwyn ; Updated September 22, 2017
An MP3's metadata stores extra, non-audio information about the file. Metadata can contain the artist and album names, the year of release, the genre of music and a picture of the album's cover art. Once you add the cover art to an MP3's metadata, the artwork appears on your computer's screen whenever you play the MP3 in a media program. Use Windows Media Player to add cover art in the JPEG, GIF, BMP, PNG or TIFF formats to the MP3s in your collection.
Open the Start menu and click "Computer." Navigate to the folder containing the cover art file that you want to embed in the MP3's metadata. Right-click the cover art file and select "Copy."
Launch Windows Media Player. Click "Library," then click "Music."
Click "Artist" or "Album." Scroll to the album to which you want to add the cover art.
Right-click the album's cover icon. Click "Paste album art" to embed the cover art into the MP3.
