Make pixel art from any picture

This free image to pixel art converter downsamples your picture into a grid of pixels and can quantize it to a limited palette for that classic retro look. Lower pixel sizes and fewer colors give a more stylized result; higher values keep detail.

Dithering for smoother gradients

When you reduce colors, dithering blends the limited palette so gradients look smoother. Try Floyd–Steinberg for photos, or Ordered for a patterned, retro feel.

Building in Minecraft?

If you want to build your pixel art out of blocks, use the Minecraft pixel art generator — it maps your image to real blocks and gives you a block shopping list and schematic export.

Frequently asked questions

How do I turn an image into pixel art?+

Upload your image, choose a pixel width, optionally reduce the color count, and convert. You get a pixelated version you can download as a PNG — at actual size or upscaled.

Is it free?+

Yes, completely free with no signup and no watermark. Everything runs in your browser, so your image is never uploaded.

What does the color setting do?+

It reduces the image to a limited palette using median-cut quantization — fewer colors give a more retro, stylized pixel-art look. Choose Full color to keep the original palette.

Can I make Minecraft pixel art instead?+

Yes — use the Minecraft pixel art generator to map your image to real Minecraft blocks with a block list and schematic export.
