How to increase image size without scale image with php

I want to change .webp image width or height to a higher value, and add some transparent area to the image.

For example, imagine I have a width:512*height:312 webp image, I need two steps:

1- Add 512*200 transparent area to my image.

2- Transform my image to the center of the new image.

OR

1- Add 512*100 transparent area to the top of my image.

2- Add 512*100 transparent area to the bottom of my image.

The final result I want, a 512*512 .webp image without any scale on my original image.

How can I do this with the PHP language?
