Meka MP3 Album Artwork Tool is a very simple yet efficient utility that allows you to complete the ID3v2 tags of your MP3 files with their corresponding cover art. Actually, you can add the selected cover image to all the MP3 files in the album in one single operation. The attached image will show up nicely in any player (hardware or software) with support for this functionality every time you listen to your MP3 files.
A simple and straightforward functionality requires a simple and intuitive interface, and that is what Meka MP3 Album Artwork certainly offers. Its one-screen interface is divided into two main panels – one for the image, and another one for the MP3 file or files to be processed. You can attach the selected image to any number of files, as long as you select all of them in the same operation - you will not be allowed to add MP3 files to the ones already selected.
The program supports JPG, BMP, and PNG image files of any size, though it is recommended that you resize them to 300x300 to ensure the maximum level of compatibility with most hardware and software music players. This tool will not resize them for you (you will have to use an external image editor for that), but it will somehow warn you – if the image exceeds the dimensions of the panel, then it needs resizing. Could not be simpler, and could not be more efficient.
