If you use the best iPhone or iPad, your favorite Mac, and maybe even an Apple TV 4K, then you may have heard about a little something called iCloud Photo Library. But what is it, exactly? Basically, it's Apple's iCloud service that allows you to access all of your photos and video from any device that is logged in to your Apple ID.

It uses your iCloud storage space to upload new photos and video from all of your devices so that they can be viewed anywhere, anytime. So if you take a photo on your iPhone 12 Pro, for example, and have iCloud Photo Library enabled, it will show up on your iPad Pro or Mac in seconds. And best of all, it'll be in full resolution!

With iCloud Photo Library, you can use it as a backup photo service, syncing service, storage optimizer, photo sharing site, and plenty more. It's a great service that makes managing all of your photos and videos easy. Here's everything you need to know about iCloud Photo Library.

What is iCloud Photo Library?

We basically gave you the gist of iCloud Photo Library earlier, but there's even more to it. In fact, while you may think it's just for photos and video that you take, it also applies for your animated GIFs, saved images from the web, screenshots, and pretty much everything else that ends up in your Camera Roll. Anything that you save into Photos on your iPhone or iPad will show up on your Mac, your Apple TV, and even on the web via iCloud.com.

The question you may be asking yourself right now is whether or not you should use iCloud Photo Library, and the short answer is yes! However, anything that is uploaded into your iCloud Photo Library will count towards your total iCloud storage, so make sure that you choose the right amount when picking your iCloud storage plan.

Apple also has another service called My Photo Stream, which is different from iCloud Photo Library. If you don't have at least a 50GB iCloud storage plan, then My Photo Stream may work better for you, as My Photo Stream just gives you access to your last 1000 photos and videos, or the past 30 days worth. My Photo Stream is better geared for those who don't take too many photos — if that's you, then you just need to enable My Photo Stream and that's it!

But if you decide to go with iCloud Photo Library for your needs, you may also be wondering about iCloud Photo Library and security. Don't worry — Apple values privacy and security, so everything is encrypted, just like your iPhone backups, iCloud Drive, and other iCloud content.

How to use and manage iCloud Photo Library

Once you have iCloud Photo Library set up, all of your uploaded images and video will be accessible on all of your devices. We have complete guides on how to use your iCloud Photo Library on iPhone and iPad, Mac, Apple TV.

Despite that fact, you can even view your iCloud Photo Library images offline if you don't have internet access. And if you have some images and video that you want to keep private, don't worry — you can keep private photos off iCloud Photo Library if need be. Your friends and family don't need to see what you don't want them to see.

And while we're at it, if you don't want your thousands of photos and videos to take up a ton of space on your local storage, make sure to use the Optimize Storage feature on your iPhone, as well as your Mac. This feature stores full-resolution photos in iCloud, rather than taking up space on your local device storage. When every little bit of space counts, this feature comes in very handy.

If you use iCloud, you also have access to iCloud Photo Sharing. This service, which is part of iCloud Photo Library, lets you share images and video from your albums with friends and family who also have an iPhone, iPad, Mac, Apple TV, or PC. However, you don't need to enable iCloud Photo Library to use share photos, and setting up iCloud Photo Sharing is pretty easy to do.
