Gradient Generator tool by VectraTools

Quick answer

A gradient generator creates smooth colour blends you can use as wallpapers, website backgrounds and social media graphics. Pick a style such as Mesh blobs or Aurora, choose four colours, adjust the softness and grain, and download a PNG at the exact size you need, from a 4K desktop wallpaper to an iPhone screen or a LinkedIn banner.

Our free gradient generator goes beyond simple CSS gradients. It paints soft mesh blobs, glowing aurora effects and radial glows on a canvas, adds optional film grain for a modern look and exports full-resolution images. You can shuffle the blob positions until the composition looks right.

Every file from the gradient generator is created on your device, so it is fast and private. You can come back to the gradient generator at any time, change a single setting and download a new version in seconds, which makes it easy to keep a consistent style across a whole project.

Designers use a gradient generator for presentation backgrounds, YouTube end screens, app splash screens and phone wallpapers. Because the gradient generator renders in your browser, you can create as many images as you like for free.

Gradient Design Tips

  • Use colours that sit near each other on the colour wheel for calm, smooth gradients.
  • Add a little grain, around 5 to 10 percent, to avoid visible banding on large screens.
  • Keep text areas on darker or calmer parts of the gradient for readability.
  • For dark mode wallpapers, start with a near-black base colour and bright accent colours.

Gradient Generator vs CSS Gradient Generator

This tool creates images for wallpapers and graphics, with effects CSS cannot easily do, such as grain and soft mesh blobs. If you need pure CSS code for a website element, use our CSS gradient generator instead.

Frequently Asked Questions

Is this gradient generator free?

Yes. It is free with no watermark and no sign-up.

Can I use the images commercially?

Yes. The gradients you create are yours to use in personal and commercial projects.

What is a mesh gradient?

A mesh gradient blends several colours from different points, creating soft, organic colour clouds instead of a straight line.

What does grain do?

It adds subtle noise that makes the gradient look like printed paper or film and hides colour banding.

Which size should I choose for a phone wallpaper?

1080 x 1920 works on most Android phones, and 1170 x 2532 fits recent iPhones.

Can I get CSS code?

Yes. Copy the CSS fallback for a linear version of your colours. The mesh and grain effects need the downloaded image.

Are images uploaded?

No. Everything is created in your browser.
