How iBoysoft Mac File Compressor Works

iBoysoft Mac File Compressor is a Finder context menu extension that allows you to zip files with customizable compression levels and encrypt ZIP files on Mac. It can save you time by combining several files into one .zip archive file before sending it with an email, save storage space by reducing file size, and improve data security by password-protecting ZIP files on Mac.

  • Create a ZIP file with multiple documents on a Mac

    Being able to compress multiple items at once is vital for a file compression app. It’s apparent that creating one ZIP file with several documents is way more effective than compressing one file at a time. With that in mind, this file zipper for Mac has made it exceptionally simple to put a bunch of files into a ZIP file.

  • Password protect ZIP file on Mac

    Another great feature of iBoysoft Mac File Compressor is the ability to encrypt ZIP files on Mac. If you’re dealing with important or sensitive information, you can safeguard the archive files on Mac with a password. This way, only those who have the password are capable of expanding the compressed files.

  • Customize the compression level of the archive files

    This compressor also lets you choose the compression level, which is handy if you are running out of space, want to speed up the zipping process, or need to make the archive smaller to match the file transfer size limitation. Its default compression level is set to middle compression, which is balanced for size and speed.

How to Compress Files on Mac with iBoysoft Mac Extension?

With this iBoysoft Mac File Compressor extension, you can compress folders and files with the ZIP archive format in 4 steps or less.


Right-click selected files and tap "Compress"

To compress multiple items at once, you can select them using the Shift or Command key if it’s convenient, then right-click or control-click them and tap the Compress button. Otherwise, just right-click one file or folder you want to compress, click Compress, then tap the "Add files" button or drag and drop to include other files for compression.


Choose a compression level

There are three compression levels to choose from. The higher the level, the smaller the archive size and the slower the compressing speed. The differences made by your choice of compression level aren’t great if you are zipping small files. But it certainly makes a big difference on large files, especially single large files.

  • High level: Select this option to create archive files on Mac with a smaller file size.
  • Middle level: This is the default option.
  • Low level: Select this option to compress folder or files at a faster speed.

Set a password for the compressed files

To encrypt ZIP files on Mac, click the yellow lock next to "Set password," then enter your password twice and tap OK.


Click Compress to start file compression

Tap the Compress button, choose a location, then wait for the tool to archive files on Mac. When finished, it will automatically display and highlight the .zip archive file in its folder.

File compression is a way to reduce file size to save disk space and facilitate faster file transmission over the internet. There are two types of compression: lossless compression and lossy compression.
The typical format of a lossless compression is ZIP, which replaces similar or repetitive data and patterns in a file with a unique identifier much smaller than the original word to reduce the overall size of the file and reverse these changes when unzipping the file.
