While you can’t create a compressed 7z file using WinZip, you can instead create a ZIP file that provides all the same benefits with wider compatibility. Archiving and compressing multiple files in one 7z.


But while the 7z file format boasts a slightly better compression than a ZIP file, it does not feature the same compatibility. To truly understand what the 7z file format is, you could compare it in many ways to a ZIP file. It’s similar to a ZIP file but uses a different lossless compression method called LZMA to reduce file size while preserving quality. The 7z file extension is a compressed archive format created with 7-zip open-source software.
