Our system is designed so that if we accept your artwork, the stores will too. It needs to be in the following format: 

- JPG or PNG file format 

- At least 3000 x 3000 pixels and ideally a perfect square

- Resolution of 300 DPI if possible, however we accept 72 DPI and above 

Also, only include the text of the artist name and release name, or an image with no text. Any other text such as website addresses, mailing lists etc will mean that your release will be rejected by the stores. 

Do not include anything additional that is not available on the stores. For example, if you have scanned your physical cover art, and it says that there is a poster included, this will be rejected by the stores. 

Your artwork may also be rejected if it features explicit content.
