Pixelate Background Online

See It in Action

AI isolates your subject and pixelates everything behind them — obscure a background for privacy or style with adjustable block size.

AI Subject Detection

The AI identifies your subject and applies pixelation only to the background — the subject stays crisp and sharp while everything behind them is blocked out.

🕹️

Adjustable Pixel Block Size

Slide the pixel block size from fine (small blocks, subtle mosaic) to coarse (large blocks, heavy censoring) and set the BG tolerance to fine-tune edge detection.

🔏

Privacy & Style

Use pixelation to anonymize a location, hide a messy room before a video call screenshot, or give a photo a retro game aesthetic — all in one click.
