Create a Gradient Background PNG and Copy the CSS
Design a two-colour linear or radial gradient at any pixel size, then take both the image and the code.
About the Gradient Background Generator
Nothing is added from your device here — the background is generated from the settings you choose. Width and height are typed directly and default to 1920 by 1080, which covers a full-screen backdrop or a presentation slide. The gradient can be linear, with an angle dial covering the full 360 degrees and starting at 135, or radial, which blends outward from the centre. Two colour pickers set the start and end shades.
The output is deliberately doubled up. You get a PNG at exactly the dimensions you asked for, and alongside it the equivalent CSS declaration, ready to paste into a stylesheet — the same gradient expressed as code rather than pixels. That is useful because a CSS gradient scales to any viewport and costs no bandwidth, while the PNG is what you need for a slide deck, an email header or anywhere CSS cannot reach.
Key Features
- Exact pixel dimensions: Type any width and height rather than picking from presets, so the asset matches its destination precisely.
- Linear or radial: Linear gradients get a full 360 degree angle control; radial blends outward from the centre of the canvas.
- Both colours are yours: Two pickers set the start and end shades, so the result can follow a brand palette exactly.
- CSS provided alongside: The matching background declaration is generated so you can use the gradient as code where that is the better option.
- Sized-named output: The PNG is named with its dimensions, which keeps a folder of background variants organised.
How to Use the Gradient Background Generator
- Set the width and height you need in pixels.
- Choose linear or radial, and set the angle if you picked linear.
- Pick the two colours.
- Generate, then download the PNG and copy the CSS from the box underneath.
How It Works
A canvas is created at your exact dimensions and filled with a gradient built by the browser's own drawing interface. For linear gradients the angle is converted into start and end coordinates either side of the canvas centre; for radial ones a circular gradient is drawn from the centre outward with a radius derived from the longer edge. Two colour stops are placed, one at each end, and the canvas is encoded as PNG. The design is deliberately simple, which sets its limits: exactly two colours with no intermediate stops, no transparency in the blend, and radial gradients are always centred rather than positionable.
When You Need It
An in-house designer preparing a company template needs the same brand gradient as a slide master background, as a banner behind a headline, and as a CSS rule on the intranet. Producing all three from one place keeps the colours identical instead of drifting apart across tools. There is no file to protect in this particular workflow, which is rather the point — the asset and its code are produced without an account, a signup wall or a third party recording what colours a company is about to launch with. Presenters building deck backgrounds and developers prototyping section headers use it the same way.
