Reclaim your storage. Keep what matters.
Finds exact duplicates and visually similar images without reading whole files. Native SwiftUI, under 5 MB.
Free trial: 10 scans or 7 days, whichever comes first · macOS 14+ · Apple Silicon · v1.6.4
How it works
A multi-stage pipeline that finds duplicates without wasting time reading entire files.
- Smart grouping
Files are grouped by size first. If no other file shares the same size, it’s unique, and no hashing is needed at all.
- Incremental hashing
Only the first few kilobytes of each file are hashed at first. Full hashes are computed only when partial hashes match, which skips gigabytes of unnecessary reads.
- Intelligent matching
Content hashes catch exact duplicates. Perceptual hashes find visually similar images across formats and resolutions.
Built to be smart
Fast, private, and respectful of your time.
Reads only what’s necessary. Partial hashes rule out non-duplicates early, so large files don’t slow you down.
Detects visually similar images even across different formats, resolutions and compression levels.
Tune hash quality, similarity thresholds and scan scope. You decide what counts as a duplicate.
Zero telemetry. Zero network calls during scans. Every byte is processed locally on your Mac.
Written entirely in SwiftUI. No Electron, no web wrappers. It launches instantly and feels at home on your Mac.
The whole app is under 5 MB to download and runs natively on Apple Silicon.
Pricing
Simple and honest. Every tier has all features unlocked.
Questions
Will it delete files without asking?
Never. DedupX shows you exactly what it found and lets you review every group first. You choose whether files go to the Trash or are deleted permanently, and nothing happens until you confirm.
What happens when the free trial expires?
After 10 scans or 7 days, whichever comes first, DedupX stops allowing new scans until you buy a license.
Can I transfer my license to a new Mac?
Yes. Deactivate your license on the old Mac, then activate it on the new one. Your license is tied to your email, not to a single device.
Does it work with external and network drives?
Yes. DedupX can scan any folder your Mac can access: internal drives, external USB or Thunderbolt drives, and mounted network volumes.
How is this different from other duplicate finders?
Incremental hashing reads only a fraction of each file to rule out non-duplicates early, so it’s much faster on large folders. It also finds visually similar images, not just exact copies. And it’s a native SwiftUI app under 5 MB, not an Electron wrapper.
