Keeping Data Online

I like to take a lot of pictures using my smartphone.
Using Google Photos, I am able to store all of my photos online, but I want to move them in my USB storage so I can categorize all of it.
Also, I try to keep track of my documents like utility bills and personal online receipts. 
I use a phone application to convert them into PDF.
Next March, I plan to leave my current apartment.
It will be a hassle to carry the paper documents when I move out.
Once I understand how to store my photos and documents, I can manage these files in simpler ways.
This morning, I will do all of these things.
