Since macOS is based on Unix there are a number of ways to compress files and folders within the filing system using Unix based application code, below are a few options using the Terminal or command line interface (cli). The default command line application interface in macOS is the Terminal and is stored in /Applications/Utilities. Google chrome offline installer latest.
File and folder compression saves on file size and ensures the contents are captured and delivered or stored as one monolithic file. A compressed file which contains files and folders is generally referred to as an archive. Here are some built-in compression applications you can use including zip, tar, gz, bz2, gz and dmg.
ZIP – Cross Platform
Zip File Command Line Tools for Windows, Linux and Mac OS/X. Full UTF-8 unicode filename support. Under Windows, sfk zip includes every filename twice into the zip, as 8-bit chars for old extraction tools, and as UTF-8 by an extension field. Then type sfk zip or sfk unzip for the help text.

First up is ZIP one of the most commonly used compression techniques used across all platforms

To extract
If you want to make a zip without those invisible Mac resource files such as '_MACOSX' or '._Filename' and .ds store files, use the '-X' option in the command so:
TAR.GZ – Cross Platform
Second up is TAR, an old favorite on Unix/Linux – you add the GZ for the compression – compresses tighter than zip

TAR.BZ2 – Cross Platform
Windows 10 Command Line Zip
A variation on TAR GZ but with better compression than both tar.gz and zip.

DMG – macOS Only
This one is macOSnative only – for a GUI interface use /Applications/Utilities/Disk Utility – for command line use:

You can also use a number of different formats for creating a .dmg
- UDZO – Compressed image (default)
- UDRO – Read-only image
- UDBZ – Better compressed image
- UDRW – Read/Write image
- UDTO – DVD disk image
That's the low down, the more common compression packages available will typically be covered in one of the above.
