PeaZip is a versatile file archiver with a user-friendly interface and strong cloud integration, making it suitable for users who need multi-platform support. In contrast, 7-Zip is known for its high compression ratios and efficient performance, particularly on Windows, but lacks some of the advanced features and cross-platform availability that PeaZip offers.
