Solid Color Image Generator

The Solid Color Image Generator creates an image filled with a single flat color or a smooth gradient at any width and height you set. Pick a color, choose your dimensions, and download the result as PNG, JPG, or WebP — right in your browser, with nothing to install.

It is handy whenever you need a clean colored image fast: a placeholder for a web mockup, a colored thumbnail for a video, an OG image, or a plain background for a social media post. Beyond solid fills, you can switch to a linear or radial gradient and blend up to ten colors.

Private by design: every image is rendered locally on your device's canvas. Your colors and dimensions are never uploaded to a server.

How to Create a Solid Color Image

Choose a fill mode

Use the tabs at the top to pick Solid Color, Linear Gradient, or Radial Gradient.

Pick your colors

Use the color picker, type a HEX code, or open Color Presets to choose from the Material, Tailwind, Pastel, or Flat UI palettes. The dice button rolls a random color. For gradients, add up to 10 color stops and set each one's position.

Set the dimensions

Choose a size preset for social media, web, or standard formats, or type a custom width and height in pixels (up to 7680 x 7680). Use the lock button to keep the aspect ratio while you resize. For linear gradients, set the direction with the 8 arrows or the angle slider.

Download the image

Pick PNG, JPG, or WebP in the Export box, then click Download to save the image to your device.

Frequently Asked Questions

How do I create a solid color image online?

Keep the Solid Color tab selected, pick a color with the picker or by typing a HEX code, set your width and height, then click Download. There is nothing to install or sign up for.

Can I set a custom width and height in pixels?

Yes. Type any width and height in the size fields, up to 7680 x 7680 pixels. You can also pick a ready-made preset, or lock the aspect ratio so both sides scale together.

How do I enter a HEX or RGB color code?

Type a 6-digit HEX code (for example #6366f1) into the hex field next to the color picker, and the image updates instantly. The visual color picker also lets you choose any color by eye.

Can I download as PNG, JPG, or WebP?

Yes. Choose your format in the Export box: PNG is lossless and best for solid colors, JPG makes smaller files, and WebP balances quality and size for modern browsers.

Can I make a transparent solid color PNG?

No — generated images are fully opaque with the color or gradient you choose, so there is no transparency. For a transparent background, use PNG in a dedicated image editor instead.

What is the difference between a linear and radial gradient?

A linear gradient blends colors along a straight line at the angle you set. A radial gradient blends colors outward from the center in a circle. Both support up to 10 color stops.

Is my color data kept private?

Yes. Every image is generated on your own device's canvas. Your colors, dimensions, and the final image are never uploaded, and no usage data is collected.
