The biggest opportunities appear before small photo cleanup.
iPhone photo storage
See what takes space in your Photos library before adding storage. Tasnif shows occupied space, starts with large videos, and keeps every review under your control.
Free on the App Store for iPhone and iPad.

Concrete review collections that are easy to understand.
Nothing is deleted without the standard Apple confirmation.

Sizes are checked gradually so the iPhone stays usable while you review.
Tasnif answers searches like iPhone storage full, see iPhone photo size, find large videos and clean up Photos safely.
Start with the media that takes the most space: long videos, screen recordings, RAW files, screenshots and probable duplicates.
Deleted media can remain in Recently Deleted. Check what you removed before permanent deletion.
