Pixels are small single colour boxes that, when combined, make up the foundation of a digital image. Pixelated images occur when a small resolution image is expanded through digital zoom or other enlargement methods. Because there are not enough pixels to represent the lines and contours of the image properly, the result is unnatural looking pictures or text. If the problem is minor, it is easy to correct using common image editing software, but if the pixels are extremely big when viewed at full size, there simply may not be enough data in the image to allow for a correction.

- Image editing software like Adobe Photoshop, GIMP or Corel PaintShop Photo Pro
Open your image editor and load the file you want to work on.
Click on "Image > Image Size" to open the "Image Size" dialogue box. Increase the resolution by about four times. For example, if you are dealing with a common web resolution of 72 pixels per inch, increase to about 300 pixels per inch.
Make sure "Inches" are selected from the drop down menu next to width and height. Enter the size you want in the width and height boxes. Click OK.
Click "Filter > Blur > Gaussian Blur" to run a minor blur filter on the image. This will help blend the pixels together. Make sure the preview box is checked. Set a low level of "2-5" in the filter's dialogue box. Click OK.
Run a sharpen filter to clean up your blur. Select "Filter > Sharpen." You may have to run the filter two or three times but be careful because the sharpen filter can quickly re-pixelate your image.
