How do I download and unzip files on my iPhone?

Can iOS open ZIP files?
The Files app, added in iOS 11, supports zip files. You can open them, see their contents, and extract files without any third-party apps. You’ll still need an app from the App Store if you want to create zip files. When you download a zip file in Safari, your iPhone or iPad will offer to open it in the Files app.
