Duplicate photos pile up from messaging apps, edits, screenshots and backups. Removing them can free real space - as long as you review before you delete and keep a backup. Menu names vary between phones.
Messaging apps save received photos into their own folders, editors keep the original and the edited copy, burst shots create near-identical frames, and screenshots are often taken more than once. Some are exact copies; many are only similar.
Exact duplicates are byte-for-byte identical files and are safe to treat as one. Similar photos - bursts, slightly different angles - are not duplicates: one of them may be the good one. Review similar photos by eye.
Your gallery or cloud photo app may offer a duplicates or clean-up view. Otherwise, open the Files app, browse Images and sort by name or size: copies often sit side by side with names such as IMG_1234 and IMG_1234(1). Also check the folders created by messaging apps.
Make sure the photos are backed up before removing anything, and check the backup contains them. Deleting through the gallery or Files app lets you use the recently deleted or trash folder as a safety net for a while.
Delete one folder or one day at a time and look at the result. If you remove the wrong copy, restore it from the trash while it is still there.
Old screenshots and long videos often free more space than duplicates. Sort by size, review the largest items and keep what matters.
Rain Cleaner for Android finds duplicate photos (by content, not by name), old screenshots and big videos, shows them to you, and asks for your confirmation through Android's own dialog before anything is removed. No ads. You can do the same by hand with the Files app - the app just collects the candidates in one place.

They can be. Exact duplicates have identical content even if the names differ; similar photos are different shots and need a look.
Often, from the gallery trash or recently deleted folder for a limited time, or from your backup - which is why you back up first.
