Photos on Mac features an immersive, dynamic look that showcases your best photos. Find the shots you’re looking for with powerful search options. Organize your collection into albums, or keep your photos organized automatically with smart albums. Perfect your photos and videos with intuitive built-in editing tools, or use your favorite photo apps. And with iCloud Photos, you can keep all your photos and videos stored in iCloud and up to date on your Mac, Apple TV, iPhone, iPad, and even your PC.
A smarter way to find your favorites.
Photos intelligently declutters and curates your photos and videos — so you can easily see your best memories.
Focus on your best shots.
Photos emphasizes the best shots in your library, hiding duplicates, receipts, and screenshots. Days, Months, and Years views organize your photos by when they were taken. Your best shots are highlighted with larger previews, and Live Photos and videos play automatically, bringing your library to life. Photos also highlights important moments like birthdays, anniversaries, and trips in the Months and Years views.
Your memories. Now playing.
Memories finds your best photos and videos and weaves them together into a memorable movie — complete with theme music, titles, and cinematic transitions — that you can personalize and share. So you can enjoy a curated collection of your trips, holidays, friends, family, pets, and more. And when you use iCloud Photos, edits you make to a Memory automatically sync to your other devices.
The moment you’re looking for, always at hand.
With Search, you can look for photos based on who’s in them or what’s in them — like strawberries or sunsets. Or combine search terms, like “beach 2017.” If you’re looking for photos you imported a couple of months ago, use the expanded import history to look back at each batch in chronological order. And in the Albums section, you’ll find your videos, selfies, panoramas, and other media types automatically organized into separate albums under Media Types.
Fill your library, not your device.
iCloud Photos can help you make the most of the space on your Mac. When you choose “Optimize Mac Storage,” all your full‑resolution photos and videos are stored in iCloud in their original formats, with storage-saving versions kept on your Mac as space is needed. You can also optimize storage on your iPhone, iPad, and iPod touch, so you can access more photos and videos than ever before. You get 5GB of free storage in iCloud — and as your library grows, you have the option to choose a plan for up to 2TB.
Make an edit here, see it there. With iCloud Photos, when you make changes on your Mac like editing a photo, marking a Favorite, or adding to an album, they’re kept up to date on your iPhone, your iPad, and iCloud.com. And vice versa — any changes made on your iOS or iPadOS devices are automatically reflected on your Mac.

All your photos on all your devices. iCloud Photos gives you access to your entire Mac photo and video library from all your devices. If you shoot a snapshot, slo-mo, or selfie on your iPhone, it’s automatically added to iCloud Photos — so it appears on your Mac, iOS and iPadOS devices, Apple TV, iCloud.com, and your PC. Even the photos and videos imported from your DSLR, GoPro, or drone to your Mac appear on all your iCloud Photos–enabled devices. And since your collection is organized the same way across your Apple devices, navigating your library always feels familiar.
