How do I pixelate an image?

Upload your image, adjust the pixel block size slider (2–100px), then click Pixelate. Download the pixelated result.

What is the difference between pixelate and blur?

Pixelation creates a mosaic of visible square blocks, while blur smooths transitions between pixels. Pixelation gives a retro or artistic look; blur softens the image.

Can I pixelate multiple images at once?

Yes. Upload multiple images and the same pixel block size will be applied to all. Download individually or as a ZIP.

Is the pixelate tool free?

Yes, completely free. No account required, no watermarks.

Are my images private?

Yes. All processing happens in your browser using the Canvas API. Your images never leave your device.
