The Snap Store
Linux Snap Store utilizes a 3:1 wide banner, 1:1 square icon (≤ 256 KB), and up to 5 screenshots (≤ 2 MB each, aspect ratio between 1:2 and 2:1).
Snapcraft (Linux) Guidelines Summary
Strict 3:1 banner, 256 KB icon & 2 MB screenshot limits
Store banner must strictly adhere to 3:1 (1920 × 640 px recommended, min 720 × 240 px). Maximum file size is strictly 2 MB.
The 512 × 512 px icon must not exceed 256 KB. Our engine applies intelligent quantization to preserve transparency while keeping bytes within limit.
Snapcraft allows maximum 5 screenshots. Aspect ratio must fall strictly between 1:2 and 2:1 (e.g. 1920 × 1080 px). Max 2 MB per screenshot.
Upload your high-res square logo. Used for Google Play (512px), Apple App Store (1024px), Windows Store (300px), and Snap Store.
