A pixel is the smallest piece of a digital image, arranged in rows and columns. When you reduce the resolution of your image, the size of the pixel increases and produces blurring. You can use the Pixelate effect to increase the size of the pixels in your image, and save your options as a preset for future use.
To apply a Pixelate effect:
- In Edit mode, in the Add group, click Special Effect.
- Click Pixelate.
- On the Pixelate tab, drag the Width and Height sliders to set the size of the pixels in your image. Select the Square check box to make the width and height equal.
- Do one of the following:
- Click Done to accept your changes and close the pane.
- Click Cancel to discard your changes and close the pane.
