Original Title: Download

Sorry, NOT possible. Your iPhone can support the highest version of iOS 16 and nothing higher. You have an 8 year old phone, which is considered Vintage, but will in the coming months become obsolete. If you need a higher version iOS, then it's time to retire you old phone and buy a new one.

You don't. iOS 16 is the highest version you can install on an iPhone 8.

iPhone 8 Plus is not compatible with iOS 17, 18, 26, 27.

Time to start looking for a new iPhone.
