Hi. I am planning on factory reseting my phone. However I still want to store my photos on Icloud. I’m quite sure I know how to, maybe it’s me being overly careful but I reallt don’t want to make a dumb mistake that removes all my photos and videos. Therefore I want to ask how you:

1: How can i send over all my photos and videos to icloud in goos quality. (The ones I sent to google drive got their quality lowered).

2: How can I know for sure that when I reset my phone completely, their still safe?

And 3: When I log back in with my new reset phone, can I get them all back? If so, how?

Thanks! Feel free to talk to me like an idiot because I really don’t want to mess this up.
