Censorship Drawing & Artistic Pixelization

Mosaic censorship isn’t just for hiding things — it's also a growing artistic trend. Designers and illustrators use pixelization to evoke nostalgia, glitch aesthetics, or surrealism.

You can create an entire censorship drawing by strategically applying the mosaic blur to faces, bodies, or objects, transforming your image into something abstract or symbolic.

For artists and creators, BlurMe offers full control over how and where you apply the effect — whether it’s just a censor bar over eyes or a full-face pixelization.
