The fastest way to convert an image to pixel art

Upload, pick a pixel size, and convert — that's it. Reduce the palette for a retro sprite look or keep full color for a faithful pixelated photo. Export at actual size for sprites or upscaled for posters and avatars.

Frequently asked questions

How do I convert an image to pixel art?+

Upload the image, set the pixel width and number of colors, choose a dithering style, then click convert and download the PNG.

Is anything uploaded to a server?+

No. All processing happens locally in your browser, so your images stay private.

What's the best size for an avatar or sprite?+

Try 32 or 64 pixels wide with 16–32 colors for a clean sprite look. Use the upscaled PNG export so it stays crisp when displayed.
