The PI3 file type is associated with Degas & Degas Elite, which are image editing and drawing applications specifically designed for the Atari ST series of computers. These files contain images created or edited within the Degas or Degas Elite programs, capturing graphics in a format that supports the unique capabilities and limitations of the Atari ST's display. The PI3 format is particularly tailored for high-resolution monochrome images, reflecting the hardware's graphical output options at the time. While now considered a legacy format, PI3 files represent an important part of digital art history, especially within the context of early personal computing.
Based on HEVC (High-Efficiency Video Coding), the HEIF format is an image file container with one or multiple images and is the default image format for Apple Live Photos. It replaced the JPEG format as it's smaller in size and has lossless compression ensuring high-quality photos.
