FAQ
Pixelizer questions
How do I pixelate an image online?

Is this image pixelizer free?
Yes. Pixelate Image is free to use with no account or signup required.
Do images leave my browser?
No. The tool renders your image locally with HTML canvas. Your file is not uploaded to a server.
Can I pixelate a face for privacy?
Yes. Load a portrait or screenshot and use a larger block size for a privacy effect. The effect covers the whole canvas, so crop first if you only want to cover one face.

Use 8–18 px for subtle texture, 24–48 px for visible pixel art, and larger values for bold mosaic blocks.
