Image Pixelator

KeepVid Image Pixelator was built for the moment you want a photo to look retro, blocky, or simply private. Turning an image into pixel art or censoring a detail usually means a desktop app or a server that keeps your picture, which feels like overkill for one effect. Our tool runs entirely in your browser, so you can pixelate any JPG, PNG, or WebP photo by dragging a single slider. It samples the average color of each block and fills it, creating a clean mosaic without uploading your file. The core function stays simple: open a photo, set the block size, optionally pick a shape, and download. A live preview shows the result as you adjust, so you land on the exact look before saving. Nothing is uploaded, nothing is installed, and no account is required.

Behind that simplicity are controls that go well beyond a basic mosaic. The block size slider moves from subtle to chunky, while the color levels control posterizes the palette for an authentic 8-bit retro feel. Selective pixelation lets you drag a box or pick from more than ten shapes such as circle, star, or heart, so only the chosen region turns blocky and the rest of the photo stays sharp. Grid lines add a classic tile effect for posters and art, and output stays flexible across PNG, JPEG, and WEBP. Because all rendering happens on your device, your photos never leave the browser, which keeps sensitive screenshots safe. In practice, Image Pixelator is used for retro avatars, privacy censoring, game sprites, and creative social posts. It is free, works on phones and desktops, and needs no plugins.
