🎨 Pixel Mosaic

How to use: Upload an image, adjust the pixel size (up to 128) and color limit sliders, then click "Pixelate Image" to see the result. Enable "Edge-Aware Pixelation" for adaptive grid optimization - you can control how many optimization iterations the algorithm performs and adjust edge sharpness (0-1, default: 0.8 for strong edges). Enable "Apply Rotation" to see a projective transformation example.
