Convert pi4 to png

What is the difference between .pi4 and .png?

Description: The PI4 file type is associated with Degas & Degas Elite, which are image file formats used primarily on the Atari ST series of computers in the 1980s and early 1990s. These files contain bitmap graphics created or manipulated within the Degas or Degas Elite drawing programs, which were notable for their powerful features and user-friendly interfaces during their time. PI4 files specifically represent images saved in a low-resolution mode, which typically means a palette of 16 colors from a selection of 512, at a resolution of 320x200 pixels. The format was widely used for digital art, game design, and multimedia presentations within the Atari ST community.; 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.
