How large is the library in iCloud?


Even with optimize Storage you cannot remove the library completely from your device and keep it only in iCloud. You still need a local copy of the library with the thumbnails and previews, the metadata, the albums, etc.

The "Optimization" will at most remove the original image files and replace them by smaller, optimized versions. Depending on the format and size of your originals, the fully optimized version of your local Photos library can shrink down to 10 % of the size of the full library, but typically the optimized library on my mac with the least storage has a size of 25% of the library in iCloud.
