Open Pixel Snapper

How To Use It

1. Upload an image, or drag it onto the page
2. Choose the Colors amount
3. Download the result image (PNG)

Colors

The Colors slider controls the output palette size.

It goes from 8 to 64 colors.

Use fewer colors when the source image has noisy pixels or too many near-duplicate shades.

Use more colors when the source image has important details, gradients, dithering, or subtle color ramps.

Custom Palettes

Use a custom palette when the result must match an existing game, sprite, or tileset color palette.

Browser

Click Import palette PNG next to the Colors setting, then choose a PNG containing your palette. Pixel Snapper reads between 1 and 256 distinct visible colors from the image.

Browse popular pixel art color palettes to download a palette PNG, or import your own.

CLI

Pixel Snapper's open-source GitHub repository includes a CLI. For example, use --palette to process an image with your colors:

cargo run input.png output.png --palette "1a1c2c,5d275d,b13e53,ef7d57,ffcd75"

WebAssembly

Pixel Snapper's open-source GitHub repository also supports WebAssembly. For example, pass your colors as the fourth argument to process_image:

const result = process_image(inputBytes, null, null, "1a1c2c,5d275d,b13e53,ef7d57,ffcd75");

Use Pixel Snapper for
