Certain matches, careful cleanup

Byte-identical matching

Documents are compared byte-for-byte, so a match is a true duplicate — never two different versions of the same contract flagged by guesswork.

Review everything first

Matches are grouped with file type and modification details. Reveal files in Finder or copy their paths before anything moves.

Trash, not delete

Removed files go to the macOS Trash, where you can recover them at any time. Nothing is deleted permanently.

100% on-device

No accounts, no analytics, no cloud. Your documents are scanned locally and never leave your Mac.

Frequently asked questions

Are my documents uploaded anywhere?

No. Duplicate Document Cleaner scans entirely on your Mac. It has no accounts, no analytics, and no tracking — your documents never leave your computer.

How does it decide two documents are duplicates?

It compares files byte-for-byte, so a match means the files are truly identical — there are no fuzzy guesses that could flag different versions of a document as the same.

Is it safe? Can I recover removed files?

Yes. Files you remove go to the macOS Trash, where you can recover them at any time. You review every match before anything moves.

How much does it cost?

The app is free to download and scan one folder for duplicate documents and PDFs. Pro is a one-time $9.99 in-app purchase — no subscription — that unlocks multi-folder scans, All Files mode, CSV export, group selection, and Trash tools. Restore it on any Mac signed in to your Apple ID.

What does it need access to?

Only the folders you choose. The app is sandboxed by macOS and can't touch anything you haven't explicitly selected.
