I built a wallpaper generator. It runs entirely in the browser, exports at any resolution, and has sixteen different styles — from layered waves to low poly meshes to a fully animated particle system. No sign-up, no watermark, no cost.
Here it is.

How It Works
Pick a generator from the left panel — Layered Waves, Blob Scene, Polygon Scatter, Cityscape, Interstellar, and thirteen others. Each one has its own set of controls: layers, variance, smoothness, angle, size, density, depending on what makes sense for that style. Adjust until it looks right, or hit Randomise and see what comes out.
Colours are fully customisable. Add as many fill colours as you want, and the generator will work with them. There are preset palettes if you want a starting point, or you can build your own from scratch.
When you are happy with the result, choose a format — Mac 4K, iPhone, iPad, 1080p, 4K UHD, square, Twitter cover, Facebook cover, and more — and download. The file is a high resolution PNG ready to use.
The Sixteen Generators
Each one produces a distinct visual style. A quick summary of what each does:
Layered Waves, Stacked Waves, Layered Peaks, Layered Steps — variations on stacked organic shapes. Waves feel fluid, peaks are sharper, steps are more geometric. The layered series is the most versatile for phone wallpapers.
Blurry Gradient — soft colour blobs that blur into each other. Works well in pastel palettes. Very iOS-circa-2021.
Blob Scene, Blob Scatter — organic rounded shapes, either composed into a scene or scattered randomly. The scene version has a more deliberate feel; the scatter is more energetic.
Circle Scatter, Polygon Scatter — geometric shapes distributed across the canvas. Polygon Scatter mixes triangles, squares, pentagons and hexagons, both filled and as outlines. The Polygon Scatter set already has its own post in the Wallpapers section.
Diagonal Stripes, Geo Scatter, Low Poly — stripes are clean and minimal; Geo Scatter is tighter and more dense; Low Poly generates a triangulated mesh that looks like a faceted crystal structure.
Interstellar — a star field with a deep space feel. Good for dark wallpapers where you want something subtle behind app icons.
Particles — animated particles connected by lines when they come close to each other. The only animated generator in the set — export as a static frame or just use the live preview as a screensaver.
Cityscape — the flat minimal city silhouette with buildings and clouds. The Cityscape wallpaper set posted here earlier uses this generator.
Map — generates an abstract topographic map with contour lines. Interesting as a desktop background.
A Few Tips
The Seed field at the bottom locks the random layout so you can adjust colours or settings without losing a composition you like. Copy the seed number before you start tweaking.
The flip and rotate buttons next to the aspect ratio controls let you mirror or rotate the output — useful when the composition feels slightly off but you like the overall feel.
For phone wallpapers, switch to 9:16 ratio before adjusting controls. The composition changes when you change the canvas shape, so it is worth setting the ratio first.
Dark palettes with one bright accent colour tend to produce the best results across most generators. The Layered Waves and Polygon Scatter generators are particularly good with a near-black background and one saturated colour.
