One cover. Every size the pipeline demands.
Stores want 3000×3000. Socials want squares and banners. Drop your art once — get the full size set as JPEGs, with an honest warning if the source can't survive the enlargement.
Nothing is uploaded — your audio never leaves your device.
Sizing is mechanical. The pack behind the cover is the product.
KitDL's hosted pack pages will carry this art on a page built to convert. Until then, the studio builds what goes inside: 3 full packs free.
The size ladder every release climbs
One piece of art ends up in a dozen frames: the 3000×3000 master a distributor wants, the 1400×1400 floor most stores enforce, the mid-size squares product pages actually serve, and the 500-pixel thumbnail where most people will only ever meet your cover — in a search result, a playlist row, a store grid. The mistake that quietly ruins releases isn't bad art; it's the wrong direction of travel. Shrinking a large image is lossless in spirit — detail collapses gracefully. Stretching a small one invents nothing: an 800-pixel export scaled to 3000 ships exactly as much information as it had, spread thinner and blurrier.
That's why this tool is a checker first and a resizer second. It measures your source honestly and marks each rung of the ladder as clean (downscaled from real pixels) or upscaled (soft by construction, flagged so you can decide). The exports themselves are high-quality JPEGs rendered with proper resampling — each one named by its size so the delivery step is mindless, and the whole set downloads as one ZIP.
Two habits worth stealing from art directors: check the 500-pixel export before you commit, because if the title reads there it reads everywhere; and keep one oversized master (3000 or larger, PNG if it's flat graphics with text) in your project folder forever, so every future format request is a downscale away. The ladder only works if you start at the top.
Frequently asked questions
What size does cover art need to be?
3000×3000 JPEG is the safe modern deliverable for stores and distributors (minimums hover around 1400×1400, but 3000 future-proofs). This tool exports 3000, 1400, 1000, and 500 squares in one pass — the whole ladder.
What if my source image is smaller than 3000×3000?
Upscaling can't invent detail — a 800px image stretched to 3000 ships blurry. The checker measures your source and says plainly which sizes it can honestly fill. For real enlargement you want a new export from the original artwork file.
Why JPEG and not PNG?
For photographic and painted covers, high-quality JPEG (this tool exports at 90+) looks identical at a fraction of the size, and every store accepts it. PNG matters for flat graphics with text — if that's you, keep a PNG master and use these JPEGs for delivery.
Does text survive the small sizes?
Check the 500px export — that's roughly how your cover looks in a search result. If the title is unreadable there, it's unreadable where it counts. Big type wins streaming.
