How to Make a Zip File on a Mac | Digital Trends

Creating zip files on a Mac might seem daunting at first, but you have a few options — and plenty of MacOS and iOS tools — at your disposal. While you may have experience creating a zip file on a Windows-based computer, the process is slightly different on a Mac.

Thanks to this guide, you’ll become a pro at zipping and unzipping files between your Mac, iPad, and iPhone in no time. If you want to secure your zip files with a password, we have a guide for that too.

What is a zip file?

Sending big files can take a long time. Zip files are a way to compress your data to make it more compact and quicker to transfer. Compression can temporarily remove redundancies in the files, which can then be re-created (lossless). Compression can also permanently remove unnecessary bits, albeit at the cost of a perfect replica (lossy). Another popular form of compressed, or archived, data is RAR.

When you download a compressed file, you will need to extract the contents — or “unzip” them — in order to access them.

How to create a zip file on a Mac

Creating a zip file on a Mac is quick and easy, as MacOS includes a built-in tool called Archive Utility for compressing and unzipping files. You don’t need a third-party utility.

Zip a single file

Right-click or press Control + Tap on a file you want to compress and select Compress [File Name] on the pop-up menu.

As shown below, a new zip file appears in the same folder, while the original file remains.

MacOS New Zip File

Zip multiple files

Step 1: Hold down the mouse button or trackpad to draw a box around all the files you want to compress. Alternatively, press the Command button while tapping the trackpad or while clicking the mouse button to select specific files.

Step 2: Right-click or press Control + Tap and select Compress on the pop-up menu.

MacOS Compress Multiple Files

A new, single archive will appear in the folder. As before, the original files remain intact.

Step 3: To rename the default file name, simply right-click or press Control + Tap on the archive and select Rename. This is useful if you need to create multiple zip files or to make it easier for the recipient to know what’s in the archive.

How to unzip a file

There’s nothing complicated about unzipping a zip file. Your zip file will open automatically with a click of your mouse or touchpad. 

Alternatively, right-click or press Control + Tap on a zip file, hover over Open With on the pop-up menu, and then choose Archive Utility. Unzipping software like The Unarchiver is also available to use if your computer doesn’t have a set unzipping feature that you can default to.

Mac Open Zip Files Third Party

MacOS has engineered a handy system of organization in which you can find decompressed files and zip files in the same newly created folder.

Fix Archive Permissions

Perhaps you cannot compress files because file permissions aren’t letting you. You can change file permissions by following these steps:

Step 1: Right-click or select Control + Tap on the file you want, and choose Get Info from the resulting menu.

Step 2: Click the arrow beside Sharing & Permissions to open this choice, as displayed above.

Step 3: Check that your specific account is set as an administrator and that your permissions are Read & Write or Read Only. Any other settings may prevent you from compressing the file.

If you’re not an administrator, click the Lock button and log in with administrator credentials. Then, switch your permissions to Read & Write or Read Only and try compressing the file once more.

Sending compressed files to iOS/iPadOS

iPadOS Unzip Archive

Swapping files between macOS and iOS devices is tricky but unavoidable. You’ll need to complete a few more steps to uncompress the files on your cellphone or tablet.

Step 1: Click the Files application and locate the file in question.

Step 2: Click and hold the file and choose Uncompress. You’re all done.
