Zero Duplicates finds duplicate downloads, documents, PDFs and more by comparing their content, even when the names differ, and moves them safely to the Trash.
Zero Duplicates finds duplicate files on your Mac by comparing their content, not their names. It scans the folders you choose, groups every duplicate for review, and removes unwanted copies safely.
CONTENT MATCHING, NOT NAME MATCHING
Many duplicate finders only compare file names. Zero Duplicates compares the actual file content, so it finds:
• Photos and videos saved under different names
• Documents that were renamed or copied between folders
• Music files with different tags or metadata
• Backup copies scattered across drives and cloud folders
AUTO-SELECT IN SECONDS
Automatic selection picks duplicates for you: keep the newest or the oldest file in every group, or decide by folder and keep the copies that live where they belong. Review the selection, then clean up gigabytes in one step instead of clicking through thousands of files.
BUILT FOR THE MAC
• Native macOS app with full Dark Mode support
• Quick Look previews before anything is deleted
• Drag and drop folders straight from Finder
SAFE BY DESIGN
• Scanning happens locally on your Mac. Files are never uploaded.
• You choose how duplicates are removed: move them to the Trash or delete them permanently.
• Files moved to the Trash can be restored at any time.
• At least one copy of every file always remains. Losing all copies is impossible.
• System files are protected automatically.
• Nothing is deleted without explicit confirmation.
MADE FOR REAL LIBRARIES
• Photo collections: JPEG, RAW, HEIC
• Music libraries: MP3, FLAC, AAC
• Documents: PDF, Word, spreadsheets
• Videos: MOV, MP4 and more
• Backup and sync folders: cloud drives, external disks
PERFORMANCE

Truly exceptional
Varcos
I have LOTS of duplicates on an old Intel MacBook Pro. And when I say a lot, I mean over 52k duplicates. While it’s not super fast for me to delete the files because the list has over 82k (so, I’m trying to get it down to the 30k unique files) But it WORKS!! And, right now, it’s FREE!! I’ll tell you now, this will be a paid product soon, because it really should be. I’m extremely impressed. I wish that there was some way I could possible setup duplicates that are in specific folders to all be selected for deletion or something to help me get through this LARGE list of dups, but right now I just go through them a bit every day and can be comfortable in knowing I’m not deleting anything that I shouldn’t be.
Developer Response
Thank you very much for the detailed and thoughtful review.Since then, I've added several features that may help with large duplicate sets like yours. The app now includes the ability to select multiple files in a folder, as well as automatic selection, which can significantly speed up the cleanup process for very large libraries. Since then, the app has evolved and is no longer free.I really appreciate you taking the time to share your experience. Feedback like yours directly helped shape these improvements.
Lifesaver!

I’ve been trying to migrate my notes from Evernote to another app, and the process has been ridiculously involved and time-consuming, resulting in the creation of a massive number of duplicate files - 4,800, according to this app - scattered among multiple folders. Thanks to a Reddit comment, I found my way here and, within minutes, the problem was taken care of. So grateful for a stable, functional app. Thank you, developer friend!
Developer Response
I'm glad to hear you found my app helpful for your note migration! Thank you for sharing your experience and writing this review!
Very limited and some buggy
Fotopro4you
There are numerous bugs. For example if you cancel a scan you have to restart the app from scratch before you can do another scan. There’s no way to refresh a scan after changing the exclude criteria—you have to start over. While there’s an exclude list by files type there’s no option to include only certain files which would be extremely useful. There’s no option to sort the duplicate list by any criteria. And it completely lacks features like finding similar photos.It’s a decent first attempt for the price for very simple de-duplication but there are much better options. I’m surprised this has as many 5 star reviews as it does.
Developer Response
Thank you for taking the time to share your feedback.A few points may have caused some confusion. After cancelling a scan it should be possible to start a new one immediately without restarting the app. If that did not work on your device, please feel free to contact support so I can look into what might have happened.The results list can also be sorted, for example by duplicate size or by the number of files in a group.Regarding similar photos: the app intentionally focuses on finding true duplicates based on the exact file content. It is therefore not designed as a similarity scanner for visually similar images, which is mentioned in the description of how the detection works. Thank you again for trying it and for sharing your thoughts.
Easy to Use with confidence

There are so many options out there for managing duplicate files and it feels like I’ve tried all of them. But, as of now, this is my favorite. I feel confident in the results and user interface is very simple. - Would love to see addition of multiple filter and sorting options, by type, kind, creation, modification, et cetera.
Developer Response
Thank you! Really glad the results feel trustworthy and the interface clicks for you. Filter and sorting options by type, date modified, and so on are great ideas and already on my radar. I'll keep that in mind as I continue developing the app.
A redesigned interface and improved user experience.
