Gradient Image Generator — wallpapers + CSS code
Generate gradient background images online: linear / radial, adjustable colors and angle, curated presets, one-click 1080P / 2K / 4K wallpaper sizes, PNG / JPG export, plus copyable CSS gradient code. Works on desktop, tablet & mobile — generated locally, nothing uploaded.
background: linear-gradient(135deg, #6366F1 0%, #EC4899 100%);
A gradient image blends two colors smoothly — a staple for wallpapers, poster backdrops, web banners and stream backgrounds. Pick a start and end color (or a curated preset), choose linear or radial, adjust the angle, then enter a size or hit the 1080P / 2K / 4K / phone presets, preview live and export PNG / JPG. Developer bonus: the page also outputs the equivalent CSS linear-gradient / radial-gradient code with one-click copy — for web backgrounds, CSS beats an image file. Everything is generated locally in your browser; nothing is uploaded.

Gradient Image FAQ
Large smooth gradients can band at 8-bit color depth, and JPG compression makes it worse. Export PNG to reduce it — or use the provided CSS code for web backgrounds, which browsers render smoothest.
Currently two colors (start + end), which covers most wallpaper / backdrop needs; multi-stop gradients may come later.

No — gradients are drawn locally with the browser Canvas and never touch a server.
