How can I transfer photos and videos to albums in Photos app on iPhone?

You cannot physically move photos or videos to an album in the Photos app on your iPhone. However, you can add the same photos and videos to multiple albums without creating duplicates on your device. When you add a photo or video to an album, you are not actually transferring it from one location to another; instead, the album functions as a virtual collection or shortcut to the original file.

All photos and videos remain stored in the Recents section of your Library, which serves as the central repository for your media. The albums you create simply reference these original files, meaning the same photo or video can appear in multiple albums while still occupying only a single instance of storage. Deleting a photo from Recents will remove it from all albums since albums do not store separate copies of photos.
