Keepr Everything about the photos themselves: getting them in, what Keepr does to them on the way, and finding one again in five years.
Two pages here are worth reading before you upload a lot: Photo and video quality, because the decision about quality is one you make at the start and can't undo later, and Print-ready originals, which is the part most people don't know exists.
The rest is about living with a large library — search, near-identical shots, and photos resurfacing from the same day years ago.
