How do i factory reset my iPhone without a computer?

Hi

Go to settings turn off find my iPhone then restore iPad back to factory settings.

Then it ready to be set back up over your WiFi .

Or setup by new user .

I have iPhone & ipad not used my PC for them for over 2Years all done over my WiFi

You can erase all contents and settings without a computer, but you can not restore to factory settings and download a clean copy of the iOS without using a computer running iTunes. If you need to restore to factory settings using iTunes, any computer with a current copy of iTunes on it will work. You can make an appointment at an Apple Store and they can do it for you.
