About this tool

Mesh gradients are the soft, multi-colour “aurora” backgrounds where several colours blend fluidly across a surface, rather than the straight line of a simple gradient. This generator builds them by layering multiple radial gradients with draggable colour pins, so you can position colours freely, adjust their spread, start from presets, and export clean CSS or a 1080p PNG.

Dragging pins and watching the blend update makes it easy to compose the flowing, organic look that is hard to achieve with linear gradients. You control where each colour pools and how far it reaches, which is what gives mesh gradients their distinctive depth.

It runs in your browser, so design is instant and private. Export as CSS to keep it lightweight and scalable, or as a PNG when you need a fixed image for a hero, a slide or a social graphic.

Frequently asked questions

What is a mesh gradient?
It is a background where several colours blend fluidly across a surface — an aurora-like effect — created here by layering multiple radial gradients rather than a single linear transition.
How do the colour pins work?
Each pin places a colour on the canvas; you drag it to position the colour and adjust its spread, and the blend updates live so you can compose the effect visually.
Can I export as CSS or an image?
Both. You can export clean CSS to keep the background scalable and lightweight, or a 1080p PNG when you need a fixed image.
When should I use CSS versus PNG?
Use CSS for a responsive, resolution-independent background with no extra request; use a PNG when a tool or platform needs an image file, such as a slide or social card.
Is it done in the browser?
Yes. Everything runs locally, so nothing is uploaded.
