How do I download Safari?

Download to what kind of device?

Safari for Windows was discontinued in 2012 and there is no current option for Safari on Windows PCs.

Safari on iPhones and iPads is not one of the apps that can be deleted but it can be removed from the Home Screen. Go to the App Library (swipe left past your last Home Screen). From there you can touch and hold an app and slide it to the Home Screen.

Another reason for it not being visible is due to a restriction. Go to Settings (or Apple menu > System Settings on a Mac) and tap Screen Time, tap Content & Privacy Restrictions, tap Allowed Apps & Features, select Safari.
