Free duplicate photo finder

How to find and delete duplicate photos

1. Open the app and choose the folder that holds your photos. Subfolders are included.
2. Click "Find duplicates". Every photo is read once; a large folder takes a few minutes the first time and seconds afterwards.
3. Review the groups. Each group shows all copies of one photo with their size, resolution and folder. The best copy is marked Keep.
4. Remove the extras. Delete them to free the space now, or set them aside in a review folder if you want to check first.

What counts as a duplicate

Identical files are the same down to the last byte, whatever they are called and wherever they sit. These are safe to remove and are selected for you.

Similar photos are the same picture saved differently: resized, re-compressed, or exported again. These are grouped but left unticked, because only you can tell whether a smaller copy is worth keeping. You can make this matching stricter or looser in the accuracy settings.

Which copy is kept

The suggested keeper is the copy with the highest resolution, then the largest file, then the oldest date. Click any photo to switch it between Keep and Remove. One copy of every photo always has to stay, so a slip of the mouse cannot wipe out a picture entirely.

Why duplicates pile up

Phone backups run twice, photos get imported from the same SD card again, chat apps save their own smaller copies, and "copy of" folders are made before an edit. In a library built up over years, a meaningful share of the disk space can be copies of photos you already have.

Questions about removing duplicate photos

Does it find duplicates with different file names?

Yes. Files are compared by their content, not their names, so "IMG_1234.jpg" and "IMG_1234 (1).jpg" or "holiday copy.jpg" are matched.

Does it find resized or compressed copies?

Yes. Besides byte-identical files, it recognises the same picture saved at a smaller size or a different quality, such as copies sent through a chat app. These are shown as "Similar" and are never selected for you.

Will it delete photos automatically?

No. Only identical extra copies are pre-selected, and nothing is removed until you press Remove and confirm. One copy of every photo always stays.

Can I undo a clean-up?

A delete is permanent because browsers cannot use the Trash. Choose "Set aside" instead and the copies go to a "_duplicates_review" folder, from which they can be put back.

Does it work on an external drive or SD card?

Yes, any folder your computer can open, including external drives, SD cards and network drives.
