Free tool

Pass artwork review the first time.

Drop in your cover and Spotify Canvas. We check size, shape, format, aspect ratio, and length against what stores require, before a rejection costs you a release date.

Cover artwork

3000 x 3000 px, square, JPG or PNG

Drop a file or click to choose

Spotify Canvas (optional)

9:16 vertical MP4, 3 to 8 seconds

Drop a file or click to choose

Files never leave your device. Two things this tool cannot check automatically: the color profile (export as RGB / sRGB, never CMYK) and whether the artwork contains logos, web addresses, or pricing (most stores reject those). Review both yourself before you submit.

Understand it, not just check it

Why this matters

Cover art is the first thing a listener sees and the first thing a store checks. Artwork that breaks store specs is one of the most common reasons a release is rejected, and a weak cover at thumbnail size costs you clicks even when it passes.

How it affects your release

A spec-clean, legible cover clears review and looks sharp everywhere it appears. A cover that is off-spec, blurry, or cluttered gets bounced, delaying your release, or slips through and underperforms in playlists and search.

Common mistakes

·Non-square images or anything under 3000 x 3000 pixels.
·Logos, social handles, web addresses, or pricing on the cover.
·Tiny text that disappears at thumbnail size.
·Exporting in CMYK instead of RGB / sRGB, which shifts colors.

Best practices

·Export a 3000 x 3000 square JPG or PNG in RGB / sRGB.
·Make it readable as a small thumbnail, not just full size.
·Keep a Spotify Canvas to a 9:16 MP4, 3 to 8 seconds, no text.
·Use high contrast so the title and art stand out in dark and light UIs.

Ship releases that just work.

Inside HypaLabs, artwork and Canvas are checked on every release, so problems surface before submission.
