PeaZip is not a monolithic compression engine; it functions as a modular graphical orchestrator and script-generation frontend compiled strictly via Free Pascal within the Lazarus IDE. Its fundamental data-handling philosophy is built on abstraction: separating the graphical user interface from the underlying mathematical operations. Instead of executing proprietary compression routines, PeaZip routes input data through an array of specialized, hot-swappable open-source command-line binaries—most notably 7z/p7zip, Facebook's Zstandard, Google's Brotli, and the PAQ algorithmic family. The architectural significance of its recent version iterations lies in this precise decoupling. By maintaining strict isolation between the UI wrapper and the execution layer, system administrators and researchers can update, substitute, or hardware-optimize backend compilation engines directly within the res directory without breaking the application's frontend logic or script-exporting capabilities.
