Pixelizer is a browser pixel art studio. Upload a photo, pick one of four quantization algorithms (Median Cut, K-Means, NeuQuant, Octree), add error diffusion or ordered dithering, then finish the work: recolor the palette, paint, fill and apply gradients on the grid, with undo. Live preview runs in the browser, no install. Export PNG or JPG with no watermark, even on the free plan. Free plan: up to 10 projects and exports up to 1080 px. Pixel Enthusiast adds cloud sync and 8192 px exports.
