Duplicate file and photo finders for Windows and Mac
Files you have more than one copy of. Byte-for-byte matches, look-alike names, near-identical photos, and whole galleries.
4 programs, free while we’re in preview. One file each. No account, no installer, nothing to uninstall.
Byte-for-byte duplicates, compared by contents rather than names, and moved rather than deleted.
The Simple one of the 4: it keeps the settings to a minimum and picks sensible defaults for you, so there is almost nothing to learn before it is useful.
Finds invoice.pdf, invoice (1).pdf and invoice_final.pdf. Never opens a file.
The Vertical one of the 4: it is tuned for that work specifically, with presets and reports built around it rather than every setting under the sun.
Finds the same photo saved twice at different sizes, which an exact-match tool never will.
The Pro one of the 4: it adds the deeper settings and finer control that people who use it every day ask for, without getting in the way on a quick job.
Which of your shares is wasting the most space on duplicate files?
The Team one of the 4: it adds what a team needs: command-line control for scripts, settings you can roll out across machines, and a record of everything that ran.
Reading on this job
- How to find duplicate photos, including resized copies An exact-match duplicate finder usually reports nothing on a photo library, and it is not wrong — every re-export changes every byte.
- How to find duplicate files on Windows and Mac Three different things get called a duplicate file, and a tool that finds one kind is blind to the other two. Here is how to tell which you have.
What all 4 of them do the same way
- Nothing is deleted. Anything a program removes is moved somewhere you can get it back from, and anything that changes files shows you the whole plan before it touches one.
- Nothing is reported back to us. No program here signs you in, phones home or counts what you did. The ones that use the network at all use it because that is the job — fetching a file you asked for, reaching a machine you named — and nowhere else.
- One file. Download it and run it. There is no installer, no runtime to fetch and nothing left behind if you delete it.
- The window and the command line are the same program. Double-click it for the window; give it arguments and the same binary runs as a command-line tool.
- The source is published for every program here, next to the download.
