How it works
Choose a size
Pick a ready-made size from the list, such as a hero, an Open Graph image or an ad slot, or type your own width and height. Lock the ratio to keep the shape while you resize.
Pick a colour
Use a suggested colour, a shade of your current colour, the colour picker, or type any hex, rgb or hsl value. The preview updates as you type.
Add a style if you want one
Keep it flat, add a soft gradient or a subtle pattern, and turn on a label that shows the size. The label is always black or white, whichever is easier to read.
Download
Choose PNG, WebP, JPG or SVG and press Download. The file is made on your device and named from the size and colour, so it is easy to find and replace later.
