Pixelate part of an image in Photoshop

Pixelate part of an image in Photoshop

I recently had to update some screenshots on the StatsMix marketing site and needed to remove some personal information like API keys from the image. I wanted to just gracefully pixelate the data, keeping the image looking nice.

I’d done it before, but couldn’t remember what steps to take. After a some trial and error, I figured it out and decided to write these steps down in case I forget (again!) or someone else can benefit from this.

  1. Open Photoshop
  2. Crop section of image to pixelate
  3. Select Filter > Pixelate > Mosaic
  4. Set the Cell Size to 3 square

Please note, I’m using a pretty old version of Adobe Photoshop (CS3) and these steps may not work anymore. YMMV.
