About the Pixelate Image Tool
Pixelation is used in art, design, and privacy protection (blurring faces). DCPIXEL computes pixel blocks by averaging colors from each region of your image directly on the Canvas API — giving you real-time previews as you adjust block size. Download as PNG instantly.
100% Private — Processed in Your Browser
Every file stays on your device. DCPIXEL processes images entirely using the browser's built-in Canvas API and WebAssembly — zero server uploads, zero data collection.
Free — No Account, No Limits
DCPIXEL is completely free with no daily limits, no watermarks, and no registration. We never process your files on our servers, so we can offer this permanently at no cost.
