Pixelate Programs
If you have a photo on your computer that contains details that you want to hide from prying eyes, you can use a pixelate program. For example, you might need to protect someone’s identity in a group photo, or you don’t have permission to display someone’s likeness or a company’s brand in a photograph that you shot. People also use pixelation for an artistic effect. Pixelate programs enlarge the pixels, or building blocks of an image, causing the image to blur.

Considerations
-
If you are using a pixelate program to hide details in an image that you don't want any unauthorized person to see, decide whether you need to destroy the original picture. You could also rename the original image to something innocuous or misleading and then hide it inside a similarly misleading folder, such as “Old Budgets.” If you are using a pixelating program for less critical images, such as simply blurring a product logo, you may feel safe to keep the original photos on your computer.
