Not all photos need cleaning, but some photos do need special attention.

The most important to clean are photos with location information. If you take photos at home, work, or places you frequent, this location information may expose your privacy.

If you're going to post photos online, on social networks, or send them to people you don't know well, it's best to clean them first.

If you're just storing photos on your phone and don't plan to share them, you may not need to clean them. But if you're worried about your phone being lost or stolen, cleaning them would be safer.

Overall, if you're concerned about privacy leaks, cleaning is always a good idea. Especially photos with sensitive location information.
