PNG Sample Files
PNG files are raster files, similar to JPGs, but also contain an alpha layer. An alpha layer allows for transparency, so it is possible to make PNG files with transparent backgrounds, or translucent areas. PNGs are popular on the web due to their great compression and the alpha layer.

About PNG files
If you've ever seen a PNG file, you know that it can be compressed and reduced without losing image quality. PNG files are used on the Internet as a way to store images. They are supported by most browsers, and they can handle images up to 48 bits per pixel, with support for grayscale images and text. Unlike other image formats, PNGs don't lose data during compression, and most computers are set up to handle them natively.
There are several different ways to save PNG files, and this article will cover the basic formats and their uses. The first step is to determine whether the format you're using will work on your computer. You'll want to consider how many channels your PNG file supports. There are different formats for storing images with different bit depths, so be sure to choose the one that suits your needs. Listed below are the various bit depths you can use and what they mean for your images.
