Pixelate Image
Drop an image and slide from subtle blur-mosaic to chunky pixel art, with a live preview that updates as you drag. Optional color-level quantization gives you that 8-bit poster look, and a grid overlay draws clean cell borders. Everything runs on the pixel data locally — export as PNG.

The 2026 state of Pixelate Image
| Field | 2026 state |
|---|---|
| Block size | 2–64px slider, live preview, nearest-neighbor sampling (crisp edges) |
| Color levels | Off / 2 / 4 / 8 / 16 / 32 per-channel quantization |
| Grid overlay | 1px lines at block boundaries, for clean pixel-art output |
| Preserves alpha | Transparency untouched — pixelate stickers and logos |
| Preview | Full-speed re-render on every slider tick (typed-array path) |
| Export | PNG at original resolution |
| Works on | PNG · JPG · WebP · GIF (first frame) · BMP |

FAQ
How do I censor part of a photo with pixelation?
This tool pixelates the whole image at a chosen block size — for redacting a region, crop to the area first (or pixelate the whole image; large blocks make text unreadable fast). Block 8–16 usually destroys readable detail while keeping context.
What does the “color levels” option do?
It quantizes each color channel to N steps (2 = pure black/white per channel, 32 = gentle posterize). Combined with large blocks you get authentic 8-bit pixel art; off keeps the original palette.
Why nearest-neighbor instead of averaging blocks?
Averaging blurs; nearest-neighbor keeps each cell a solid sample of the source, which reads as intentional pixel art and survives further downscaling cleanly. It’s also reversible-looking — the grid lines snap to exact cells.
Is there a watermark or size limit?
No watermark, no account, and no artificial size cap — the only limit is your browser’s canvas maximum (16,384px per side in Chrome). The image never leaves your device.
