This article will show you how to use Photoshop to apply a pixel effect to any image or text.
Open the image you’d like to edit in Photoshop. I’ve created some sample text that I’ll be using for the demonstration.
Once the image is loaded, use the Marquee tool to select the area of the image/text that you would like to apply the pixelate effect to.
Filter > Pixelate > Mosaic to apply the pixel effect on the selected area.
You should see a pop up box once you’ve clicked the mosaic option. It will have a preview of what the pixelate effect will look like and you will be able to modify the look by increasing/decreasing the cell size.
I used a cell size of 15 for the image below. Play around with the cell size until you are happy with how the image will look. Once you’re happy with the image click the “Okay” button and you will be done.
