Frequently Asked Questions
Check the docs or ask on our Discord server!
What is Palette Snapper?
Sprite Fusion's free pixel art color reducer. It reduces the colors of your sprites, or applies a color palette to them.
How do I reduce the number of colors in an image?
Drop your image here and set Colors, 32 by default. It runs in your browser: your images are never uploaded.
How do I apply a color palette to an image?
Pick a palette or import your own, then drop your image. Every pixel takes one of the palette's colors.
Can I use it with Claude or Codex?
Yes! Your agent can apply your game's palette to all your sprites, for free. To connect Sprite Fusion, paste these instructions into Claude or Codex: . The Palette Snapper docs have the full setup.
Can I apply the same palette to several sprites?
Yes. Add multiple images and choose a palette to process them together. All results use colors from that palette. Use a fixed palette when your sprites need to share a color set; reducing each image separately can retain different colors.
Which palette files can I import?
Lospec .hex, GIMP .gpl, Paint.NET .txt, JSON, or a PNG of the swatches, like our pixel art color palettes. Up to 256 colors.
How are colors matched to the palette?
Two ways, and you can switch between them on the result. Lightness, the default: dark colors take the palette's dark colors, and light colors take its light ones. Nearest color: each color takes the closest one in the palette.
Why does my pixel art have so many colors?
Image models, resizing, and JPEG compression add near-identical shades. A sprite that looks like 12 colors can hold thousands.
Does it invent new colors?
No. Every color left is one you drew, or one from your palette. Nothing is averaged.
Does it keep transparency?
Yes. Transparent pixels stay transparent. PNGs also come out about 70% smaller with the default settings.
How is it different from Pixel Snapper?
Pixel Snapper is built for fixing AI-generated fake pixel art, Palette Snapper fixes the colors.
Can I generate new pixel art in my palette?
Palette Snapper recolors sprites you already have. To create new ones in your palette, use Sprite Fusion's AI Pixel Art Generator: pick a preset palette or import your own.
Is Palette Snapper free and open source?
Yes, for hobby and commercial projects. It's MIT-licensed on GitHub, with a CLI and a WebAssembly library.
