What is the difference between .dd and .png?

Description: The Doodle C64 file type, with the extension .dd, is associated with images or graphics created for the Commodore 64 (C64), a popular home computer introduced in the early 1980s. These files contain pixel art or digital images specifically designed to be compatible with the C64's unique graphics capabilities, including its limited color palette and resolution. The Doodle C64 format is used by enthusiasts and artists who create retro-style graphics and games that pay homage to the era of 8-bit computing. Files of this type can be viewed or edited with specialized software that emulates the Commodore 64's graphical output.; 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.
