What is a random image generator?

This tool generates random images. It can create images of any size and colors that can be used for websites, design, presentations, or anywhere else. In the "Image Size" option, you can specify the width and height of the output image in pixels. Then, the image area is divided into a pixel grid with the pixel size specified in the option "Random Pixel Size", and each pixel is filled with a random color from the specified color palette. You can set the colors you want to use in the "Image Colors" option, and if you don't know the correct color name, you can generate it in the palette above and copy the desired name. You can also enable the color shading option, which randomly darkens or lightens each color by the specified percentage (expressed as a coefficient from 0 to 1, where 0 indicates minimal darkening, and 1 indicates maximum darkening of the pixel). The resulting random image can be previewed and downloaded in any format selected in the options. Image-abulous!


Random image generator examples

Click to try

Generate a Random Colorful Grid

This example generates a 20x20 grid of completely random colors by keeping the Colors option empty. Each random color grid block is 25px in size and the whole random image is 500x500px.

If enabled the selected colors
will be shaded.

Generate a Single-color Image

This example generates a random single-color image. There is only one pixel to generate and the only possible colors are red and green. Each time you click the "Generate a new random image" button, there is a 50-50 chance of creating a green or red pixel square.

Generate Shades of Orange

This example generates a random image with orange color shades. Each pixel color is randomly lightened or darkened by 10%, resulting in a nice palette of orange colors. Juicy!

Generate a Rainbow Palette

This example generates an image using a palette of seven colors of the rainbow. The image is divided into 7 cells, each of which can be filled with any of the 7 colors. To calculate the probability of using all the colors of the rainbow in the image, we first need to determine the total number of possible ways to color the cells, which is 7^7 = 823,543. Next, we need to calculate the number of ways to color the 7 cells with different colors, which is 7! = 5,040. Therefore, the probability that all 7 cells will be filled with different colors of the rainbow is: 5,040/823,543 ≈ 0.00612, or approximately 0.61%.

Create an RGB Noise

This example generates an RGB noise image. It creates random pixels at a very small scale and generates them in one of three colors: red, green, or blue. The image has a size of 300 by 300 pixels, resulting in a total of 90,000 small RGB pixels.

Minecraft Dirt Block

In this example, we create a dirt block from the game Minecraft. To achieve this, we create a canvas with dimensions of 400 by 400 pixels, which consists of 16 pixel squares vertically and horizontally. Additionally, we define a palette consisting of 11 shades of brown and 1 shade of gray, which corresponds to the block's palette in the game.
