How to create a ZIP file on any device
When moving files around the internet — whether on file transfer platforms, cloud storage, or email — it’s hard to beat a ZIP file. The ZIP format compresses the contents of a folder without degrading the quality of the files contained within it. You can then just as easily unzip them out of the folder. Some ZIP programs also let you encrypt ZIP files with a password so you can have some security when moving sensitive or private files. Here is how to create a ZIP file on various platforms, as well as how to open a ZIP file if you receive one.

How to create a ZIP file and how to open a ZIP file depends on what platform you are using. Most will have a built-in compression and decompression tool in their right-click file manager menu. If not, you can install a third-party tool such as WinZip, which is the gold standard for ZIP files.

The best way to create a ZIP file on Android is to install a third-party app. The gold standard in this area is WinZip, although the free version is peppered with ads. If you will be using the app a lot, consider paying to have the ads removed.
First, go to the area where your files are that you want to zip. As you can see, it also supports cloud storage accounts.
Select the files you want to compress and then tap the small zipped folder icon at the top of the screen.
It will now ask you to navigate to a location where you want the ZIP file to be saved. When you get there, tap ZIP HERE at the bottom of the screen.
Now wait as the files are compressed and placed inside the ZIP folder.
You will now see the finished folder, which you can now move, email, or share by some other means.

To password-protect a ZIP file requires a third-party tool such as WinZip, WinRAR, or 7Zip. You can also do it via the macOS Terminal.
A ZIP file in itself is not dangerous at all. However, some people use ZIP files to package malware and send it to unsuspecting people. Just like any other file you receive online, be very wary about opening it if you don’t know the sender.
Some file formats do not compress very well. Images are the best at being compressed, while video files are barely compressed at all.
You would need a third-party tool for the job. Many tools online claim to be able to do it, but the best one seems to be WinRAR. It has a repair function in its toolbar. Note, though, that nothing is guaranteed.
