Add a Pixelated or Mosaic Effect to Any Photo

The Helperzy Image Pixelate Tool applies a pixelated, mosaic-style effect to your photo and lets you download the result. Upload an image, adjust the pixel block size with a slider, and watch the effect update from a light stylized look to a heavy censor-style blur. Pixelation works by averaging the colors within square blocks and painting each block as a single color, so detail is lost in a controlled, blocky way. A small block size gives a subtle retro effect, while a large block size obscures faces, license plates, or sensitive details enough to censor them. People use it to hide private information before sharing a screenshot, to anonymize faces in photos, to create pixel-art or retro-game aesthetics, and to add a stylistic effect to graphics. Because you control the intensity, it adapts from artistic to fully obscuring. Everything runs in your browser using the canvas API, so your photo is never uploaded and stays private — which matters especially when you are censoring sensitive content. It is instant, free, and works offline once loaded.
