What is the difference between .gun and .png?

Description: The GunPaint file, with the extension .gun, is associated with the GunPaint image editing software, primarily used for pixel art and digital painting. This file type contains the project data, including layers, color palettes, and tool settings, enabling artists to save and revisit their work-in-progress. GunPaint is favored for its simplicity and effectiveness in creating detailed pixel art, making .gun files popular among game developers and digital artists focusing on retro and indie game graphics. The format supports various features tailored for pixel art creation, including pixel-perfect drawing, custom brushes, and animation frames.; 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.
