Pixel Art Converter

Pixel art is a digital style where each pixel is placed deliberately, creating recognizable images at a tiny scale. It rose out of the technical constraints of arcade machines and home consoles in the 1980s–90s — the NES, Game Boy, and early PCs had so little memory that artists had to make every dot count. Today the constraints are gone, but the aesthetic is still loved for its clarity, nostalgia, and graphic punch.

This tool brings the same look to any photo or illustration. It downsamples the image to a coarse grid, then renders each block as one solid color — the same approach that gives classic 16-bit games their crisp, blocky charm.

The pixelation happens in two steps, entirely on your device:

1. Downsample. The source image is shrunk to width / blockSize by height / blockSize using high-quality interpolation so each new tiny pixel is the average of the colors it covers.
2. Upscale with nearest neighbor. The shrunken image is stretched back to the original size with image smoothing turned off — each tiny pixel becomes a hard-edged block. That hard edge is what makes the result feel pixelated rather than just blurry.
3. Optional color quantization. If you pick a limited palette, each color channel is snapped to the nearest of N evenly spaced levels. 3 levels per channel gives 27 colors, 2 levels gives 8 — the kind of limited palette that drove early console aesthetics.
