About converting ZIP to 7Z
7Z is a compression format that generally achieves smaller file sizes than ZIP for the same content, thanks to its more modern LZMA/LZMA2 compression algorithm, at the cost of taking a bit longer to compress and requiring 7-Zip or compatible software to open rather than the near-universal support ZIP has.
Converting a ZIP archive to 7Z extracts every file and folder from the ZIP and repacks them into a new 7Z archive, preserving the original folder structure. This is useful when you need to shrink an archive further for storage or a slow upload, or when a specific tool or workflow requires the 7Z format.
Since ZIP is such a widely-supported baseline format, most people convert in this direction when file size matters more than universal compatibility.

Frequently asked questions
Will my folder structure be preserved?
Yes, all files and subfolders keep their original structure inside the new 7Z archive.
How much smaller will the 7Z be?
It depends on the content, but 7Z's LZMA2 compression is often noticeably more efficient than ZIP for the same files, especially text and uncompressed data.
Will I need special software to open the 7Z?
Most systems need 7-Zip or a similar tool, unlike ZIP which is natively supported almost everywhere.
