About this tool
Every block of the source image is averaged and repainted as a square, circle or hexagon, optionally snapped to a median-cut palette; the gaps between shapes keep the original photo visible. Selective mode restricts the effect to the rectangle you drag, inside or outside it. The image is decoded in the browser and capped at 1600 px on the long edge so the tab stays responsive — nothing is uploaded and no data leaves this page.
