Making pictures less pixelated allows you to improve their overall quality before printing them or publishing them on the Web. When a digital picture's size is increased, its quality can be adversely affected and this may cause it to become pixelated. Pixelation is an effect that causes the individual pixels of an image to appear larger than they should. You can make a picture less pixelated by using Paint, the native Windows graphics editor.
Click on the "Start" icon, select "All Programs," open the "Accessories" folder and click on the "Paint" shortcut to launch the program.
Click on the "Paint" button. Select "Open" from the actions list and use the file browser to locate the pixelated picture.
Select the "Home" tab and click on the "Resize" icon.
Type a new, lower, value in the "Horizontal" field. Paint will automatically calculate the value of the "Vertical" field to maintain your picture's aspect ratio.
Click on the "Paint" button and select "Save" to save the picture.
If the picture still appears pixelated after decreasing its image size, try reducing it again until you are satisfied with the result.
