Pixel Art Tools

Pixel art recalls the 8-bit and 16-bit console era of Mario, Zelda and Sonic. The style lives on in indie games, apps and digital art because it reads clearly at small sizes. Drawing it by hand means placing every pixel on a grid, which takes time. Converting a photo gives you a quick result that you can still steer with the settings.

The conversion scales the image down to a low-resolution grid and maps its colors to a limited palette. The pixel size or sprite size sets how blocky the result is. Palettes set the available colors, with options such as an NES-style set (41 colors), Game Boy (4 greens), CGA, EGA, Commodore 64 and PICO-8 (16 colors each), and Minecraft's 16 wool colors. Dithering mixes palette colors in patterns to suggest shades the palette doesn't have.

The results work for profile pictures and avatars, playful marketing graphics, game sprite prototypes and attention-grabbing social posts. Minecraft players use the Minecraft pixel art generator to turn images into wool block plans. Several images can become an animated GIF or a sprite sheet with a JSON frame map for game engines.

Frequently Asked Questions

What resolution should I use for pixel art?

Try a grid about a tenth or a fifth of the original size, so a 4000 × 3000 photo becomes about 400 × 300 or 200 × 150. Lower resolutions look blockier and more abstract, and higher ones keep detail but lose the pixel art look. For sprites and avatars, an exact square grid such as 32 × 32 or 64 × 64 works well. Adjust until the result reads clearly at small sizes.

Which color palette should I choose?

The NES-style palette (41 colors) works for most subjects. Game Boy (4 green shades) gives a monochrome, nostalgic result. CGA and EGA (16 colors each) give high-contrast early PC graphics, and Commodore 64 has distinctive muted tones. PICO-8 is a popular 16-color palette for modern indie art. You can also build a palette of 2 to 64 colors from the image itself. Try a few to see which suits your picture.

What is dithering in pixel art?

Dithering suggests in-between colors by placing two palette colors side by side in a pattern. From a distance the pattern blends into a third shade. It adds texture and smooth gradients within a small palette, which is why retro graphics relied on it, but it can look busy at very small sizes.

Can I convert pixel art back to a regular image?

You can scale pixel art up, but it stays blocky, since the detail removed during pixelation is gone. Special upscaling tools for pixel art can smooth it, and tracing it into vectors gives clean edges at any size. Usually the pixel art look is the goal, not a step on the way back.
