This is a simple tutorial on how to resize an image that has background transparency. This can only be done using a program that supports transparency. The video shows how to accomplish this using Paint.NET.
To get the software, download it from https://www.ninite.com
Just choose the Paint.NET option under Imaging, and then click the blue get my Ninite button. When it finished downloading, run it and it will install Paint.NET, then just hit close when it finishes.
Next open Paint.NET, and then click on file and open, and navigate to your image. After your picture is open, go to the image menu at the top, and select resize.
In the resize window you can select how to scale the image, either by percentage, or by pixel amount. You should leave the maintain aspect ratio box checked, as if you uncheck it and change the width more than height or height more than width, the image will come out looking stretched.
