About ZIP files
the universally supported archive format
ZIP is the most widely used archive format, created by Phil Katz in 1989. It compresses each file separately, usually with the Deflate method.
Sending several files as one download or attachment; Windows and macOS open ZIP files without extra software.
ZIP: what conversion changes
Converting ZIP repacks losslessly.
ZIP: settings to change
Before you convert ZIP files, you can adjust: Compression level, Split size, Password, and Root folder.
Limits of the ZIP format
Classic ZIP encryption is weak, and AES-encrypted ZIP files need a tool such as 7-Zip to open.

Why convert archives to ZIP? Every operating system opens one with built-in tools, so recipients never need to install anything.
