==== 7.2.2 PNG (for graphics, transparency) ====

* '''What it is:''' PNG (Portable Network Graphics) is another very popular image format, especially for web graphics and logos.
* '''How it works:''' PNG uses "lossless compression." This means that when you save an image as a PNG, no information is lost, and the image quality remains perfect, no matter how many times you save it.
* '''Best for:''' Images with sharp lines, blocks of solid color, text, and especially images with '''transparency'''. Transparency means parts of the image can be see-through, allowing the background behind it to show through (like a logo that floats over a website background).
* '''Weakness:''' PNG files are generally larger than JPG files, so they might load slower on websites if not optimized.
