"How to download photos and videos from iCloud.com

If you want to save copies of your photos and videos from iCloud.com to your iPhone, iPad, iPod touch, or your Mac or PC, follow these steps.

On your Mac or PC

1. On iCloud.com, click Photos and select a photo or video. Hold the command key on your Mac or control key on your PC to select multiple photos or videos. 
2. Click and hold the download button  in the upper corner of the window. If you want to download your photo or video as it was originally captured or imported, choose Unmodified Original. For JPEG or H.264 format — including edits, and even if it was originally in HEIF or HEVC format — choose Most Compatible.*
3. Click Download.

If your photos download as a ZIP archive, learn how to uncompress the folder on your Mac or your PC. "

Once you have verified that you have downloaded the photos to your computer, you can delete it from your iPhone, which will in turn delete that from iCloud to clear up space for you.
