Convert wal to png

What is the difference between .wal and .png?

Description: The WAL (Where's All the Data) file type is a texture format used predominantly in Quake II, a first-person shooter video game developed by id Software. These files contain texture data, including color, pattern, and surface information, which are applied to the 3D models and environments within the game to enhance visual realism and atmosphere. WAL files support various texture effects such as lighting, transparency, and animation, playing a crucial role in the game's graphical presentation. They are stored within the game's PAK archive files, which also contain other game data such as maps, models, and sounds.; A PNG file is an image file stored in the Portable Network Graphic (PNG) format. It contains a bitmap of indexed colors and uses lossless compression, similar to a .GIF file but without copyright limitations. PNG files are commonly used to store graphics for web images.
