Generate a flat solid-color image at any size, in PNG or JPG.
Choose a color and size, then click Generate.
Sometimes you just need a plain, flat-colored image file -- a placeholder background, a base layer for a design mockup, or a solid backdrop for a product photo. This tool generates exactly that: a solid-color image at any dimensions you specify, in your choice of exact color.
Pick your color using the color picker (or enter a HEX code directly), set your desired width and height in pixels, and choose PNG or JPG output format. Download the generated image.
A canvas is created at your specified dimensions, filled entirely with your chosen color using the canvas fill operation, then exported as an image file in your selected format.
Creating a placeholder background image while a design is still in progress. Generating a solid-color base layer for a design composition in an external editor. Producing a specific-size, specific-color image for a website background or app splash screen.
PNG preserves your exact chosen color with no compression artifacts; JPG uses lossy compression which can very slightly shift color values, especially at low quality settings -- for a color-critical use case, PNG is the safer choice.
The size you pick depends on where the image will be used, and requirements change over time, so always confirm the current specification of the platform or tool you are using. A few general rules help. For a full-screen website background, a common approach is to use a width that matches typical desktop displays, while remembering that a solid color can also be set by CSS without any image at all. For a design mockup, match the artboard or canvas size you will place it into. For a placeholder, small dimensions are enough and keep the file tiny.
Suppose you need a light gray base for a 1200 by 630 pixel social sharing card. Enter the HEX code F2F2F2, set width 1200 and height 630, and choose PNG. The tool fills a canvas of exactly that size with the color and gives you a file to open in a design app, where you then add your text and logo on top. Because the color is a single flat fill, the PNG will be very small even at a large size.
PNG keeps the color exact and is generally best for flat fills. JPG can be useful when a platform demands it or a smaller file is wanted, but its compression can leave faint variation, especially with saturated colors. If a solid-color image will be used as a base for further editing, start with PNG so the fill stays perfectly uniform.
PNG, generally -- it's lossless and preserves your exact color precisely, while JPG's compression can introduce very slight color shifts, particularly noticeable in flat, uniform color areas.
No -- this tool specifically generates a solid fill color; for a transparent image, a blank PNG with no fill would need a different tool or manual creation.
That depends on your browser and device memory. If a very large size fails, try smaller dimensions and scale up in your editor.
Often not. A CSS background color is lighter and easier to change. Use an image when a platform or app requires a file.
Use the color picker or a HEX code for exact results, since color names can be interpreted differently.
