What is a 7z file extension?

The 7z file extension is a compressed archive format created with 7-zip open-source software. It’s similar to a ZIP file but uses a different lossless compression method called LZMA to reduce file size while preserving quality.

To truly understand what the 7z file format is, you could compare it in many ways to a ZIP file. But while the 7z file format boasts a slightly better compression than a ZIP file, it does not feature the same compatibility.

7z is also an open-source format with an open architecture that allows any compression, conversion and encryption method to be used as you please.
