cover art requirements for spotify, apple music and distrokid
Distributors like DistroKid, TuneCore and CD Baby reject artwork that is not a perfect square, is smaller than 3000 by 3000 pixels, or is saved in CMYK instead of RGB. This tool fixes all three: it crops or pads your image square, upscales it with proper Lanczos resampling so it stays sharp, and always outputs an RGB JPG or PNG.
Everything happens in your browser, so your unreleased artwork is never uploaded anywhere. If your source image is very small the checklist will warn you that the upscale may look soft, because no tool can invent detail that was never there.
