About the formats

ZIP

ZIP archive

ZIP is the world’s most common archive format, bundling many files and folders into one compressed container. Every major operating system opens it natively, with no extra software.

Strengths

  • Opens on Windows, macOS and Linux out of the box
  • Bundles many files and folders together
  • Fast, lossless compression

Limitations

  • Compresses less tightly than 7z
  • Weak built-in encryption
  • No solid-archive mode

Best for: Sharing and sending collections of files that must open anywhere without extra tools.

7Z

7z archive

7z is the native format of 7-Zip, using LZMA compression to squeeze files far smaller than ZIP. It supports strong AES-256 encryption and solid archives, at the cost of needing 7-Zip-compatible software.

Strengths

  • Excellent compression ratio
  • Strong AES-256 encryption
  • Handles very large archives

Limitations

  • Needs 7-Zip-compatible software to open
  • Slower to compress
  • Less universal than ZIP

Best for: Packing large collections as tightly as possible when recipients can use 7-Zip.
