What is Pixelate Image?

Pixelate Image applies a blocky mosaic effect to an entire image. Each block samples one color and fills a square region, producing either a stylized pixel-art look or a coarse privacy effect.

How to Use Pixelate Image

1

Upload an image.

2

Adjust the pixel block size.

3

Preview the pixelated output.

4

Download the result as PNG.

Common Use Cases

  • Creating pixel-art style thumbnails.
  • Obscuring details in an image.
  • Making retro social graphics.
  • Reducing visual detail for background images.

Example Input and Output

A portrait is converted to a blocky pixel style.

Input
portrait.jpg, block size 18px
Output

Privacy

Pixel processing happens locally with Canvas. No upload is required.

Frequently Asked Questions

Does this pixelate the whole image?
Yes. This tool applies pixelation to the entire image. Use Censored Image to pixelate only selected regions.
What does block size control?
Larger blocks create stronger, chunkier pixelation. Smaller blocks keep more detail.
Is my image uploaded?
No. Pixelation runs locally in your browser.
