Intuitive Tools

Brushes, fills, palettes, and quantization.

Paint — Click and drag to color cells.

The differenceWhy Choose Pixelizer?A photo-to-pixel studio — not a mosaic slider. Real quantizers, then tools to finish the work.
Quantizers, not a slider

Median Cut, K-Means, NeuQuant, and Octree — each with a distinct look. Choose the algorithm, not a mosaic cell size.

Dithering on your terms

Error diffusion or ordered dither, with intensity. Add grain when it helps; keep clean flats when it doesn’t.

A studio after convert

Recolor the extracted palette. Paint, fill, and gradient on the grid. Undo when you miss.

Work that persists

A local gallery for every piece. Cloud sync on Pixel Enthusiast. Export PNG or JPG — no watermark.

Built for the browser

Worker-powered quantization and live preview in the browser. No install — a full studio in the tab.
