macOS allows you to compress files and folders since macOS Mojave and later versions. Besides, there are third-party Mac file compressor such iBoysoft MagicMenu, it provides more personalized settings for Mac users.
Sometimes, accumulated large files on your Mac may take up a lot of disk space, and then you need to free up disk space on Macintosh HD. One method is to compress large files and folders to release more space. Actually, macOS allows it by default.
You can select one or multiple files/folders on the Desktop or in Finder, and right-click it on Mac to choose "Compress" from the right-click menu, then, it will creat a zip file. When a single item is compressed, the compressed file bears the original item's name and a.zip extension. The compressed file is known as Archive.zip when several items are zipped at once.
If you want to choose the compress level, change the location of compressed file, you may need a Mac file compressor. Here, I'd like to recommend iBoysoft MagicMenu. It provides three compress level including high, medium, and low, you can even set password for the compressed file, and select where you want to save it. Just downlaod and have a try!
