Free up your photo library
from duplicates—without losing what matters

Bursts, edits, chat exports, resized versions. DupSweep's photo mode is smart enough to find them all, rigorous enough to verify every match before removal.

Free trial — 15 deletions. 5€ for a lifetime license.

Three ways to find duplicates

Photography, whole folders, and generic files each need a different check.

🗂️

Files mode

SHA-256 byte verification

Exact duplicates only. Two files match if their contents are identical bit-for-bit. Perfect for documents, installers, archives.

📁

Folders mode

Whole-folder clustering

Finds duplicated folder structures, not just files, and merges them safely with a full preview first.

🖼️

Photos mode

Perceptual hashing

Finds similar photos even when they're not identical: bursts, exports, resizes, chat copies. Catches what byte-matching misses.

For photo enthusiasts & creators

Why photographers need DupSweep's photo mode.

📸

Bursts & series

Found 10 frames of the same pose. Keep the sharpest one, remove the rest without hunting by filename.

🎨

Edits & exports

Original RAW, edited PSD, exported JPEG. Same photo, different formats. SHA-256 won't catch these—perceptual hashing does.

💬

Chat & AirDrop copies

WhatsApp, Messenger, and AirDrop recompress photos. DupSweep still groups them with the original when they look alike.

Reclaim your space

Keep the originals you care about. Remove duplicates, bursts, and variants in one scan. Free up gigabytes in minutes.

Frequently asked questions

How DupSweep works, what the trial includes, and how licenses work.

How does it know two files are duplicates?

For files, it first groups likely matches by name and size, then confirms with SHA-256 hashing. Two files only count as duplicates if their contents match byte-for-byte.

Will it delete files forever, or can I get them back?

Deletions go to the system Trash on macOS or the Recycle Bin on Windows — not a permanent wipe. You can restore from there, and DupSweep also has in-app Undo.

Does it work on both Mac and Windows?

Yes. There is a universal macOS installer (Apple Silicon and Intel) and a Windows installer. The same 5€ license covers both.

What’s included in the free trial?

You can download DupSweep and scan for free. The trial allows 15 deletions. Paying unlocks unlimited cleanup. Scanning itself is not capped.

What changes when I buy the 5€ license?

You get unlimited deletions. Features are the same. After payment you receive a license key on the site and by email; enter that key with your email in the app to unlock Pro.

Can it find duplicate files on OneDrive?

Yes. Scan the OneDrive folder on your Mac or PC like any other folder. Matches are still SHA-256 verified. Files that are online-only (not downloaded) are placeholders — make them available offline, then scan. DupSweep does not sign in to your Microsoft account; it reads what is on disk.

More questions
Can it find similar photos, not just identical copies?

Yes. Photo mode uses perceptual hashing (dHash + pHash), so near-duplicates — resized or slightly edited shots — can be grouped even when the files are not byte-identical.

What does DupSweep actually do?

DupSweep finds duplicate files, duplicate folders, and visually similar photos on your computer so you can free space without guessing. You choose what to remove — it never deletes anything on its own.

Does it only match by name or size?

No. Name and size are only a first pass. A file duplicate is always confirmed with SHA-256. Photos can also match by how they look (perceptual hashing), not only as identical copies.

Can I undo a cleanup after I close the app?

In-app Undo (⌘Z on Mac, Ctrl+Z on Windows) works while DupSweep is open. After you quit, files stay in Trash / Recycle Bin until you empty it, so you can still restore them there. Operation logs (JSON, HTML, PDF) record what was removed.

Is 5€ a one-time payment or a subscription?

One-time payment for a lifetime license. There is no subscription.

Can it find duplicate folders, not only files?

Yes. DupSweep clusters folders whose contents match and can merge them in place, copy the merge into a new folder, or let you review items one by one.

Does it scan USB drives, external disks, and network shares?

You pick the folders to scan. USB and external drives work if they are mounted. Network shares usually work if they show up as folders on your computer; speed then depends on the network.

Will it mess with iCloud / OneDrive files that aren’t fully downloaded?

DupSweep reads what is on disk. Cloud-only placeholders (files that are not actually downloaded) can fail or trigger a download. Prefer scanning local copies, or exclude those cloud folders.

Does any of my data leave my computer?

Scans and hashing run on your machine. File contents are not uploaded. Buying a license uses Stripe and email only for payment and the key. The optional contact form sends only what you type.

How do I activate the license after I pay?

After a successful payment the key is shown on this site and emailed to you. In DupSweep, open the license / register dialog and enter the same email you paid with plus the key.

Can I use one license on more than one computer?

The key is tied to your email, not to a specific device. You can enter the same email and key on your own Mac and PC. It is a personal lifetime license, not a team or seat pack.

What if I reinstall the app or get a new machine?

Install DupSweep again and enter the same email and key. If you lost the key, check the purchase email or use the contact form on this page.

Does it scan system folders or application files?

It scans the folders you select. It does not specially lock the operating system, so avoid system directories. You can exclude folders (for example node_modules or .git) and file types before you clean.

Will a large scan slow my computer down?

A large scan uses CPU and disk while it hashes files. You can keep working; it may feel slower on spinning hard drives or huge photo libraries. Size and include/exclude filters shrink the job.

Where do I get support or suggest a feature?

Email support@dupsweep.com or use the Contact / Feature Request button at the bottom of this page. Choose Support or Feature Request so the message is tagged correctly.

What should I know before installing on macOS?

DupSweep includes a universal installer for Apple Silicon and Intel. On first launch, macOS may show a Gatekeeper warning because the installer is not notarized yet — open it from Finder if your system blocks the double-click. If you use iCloud Drive, note that cloud-only files are just placeholders on disk; make them available offline first, or exclude those folders from your scan.

What should I know before installing on Windows?

Windows SmartScreen may warn on first launch because the installer is not signed yet — choose "More info" → Run anyway if you downloaded DupSweep from this site or GitHub Releases. For OneDrive users: add the OneDrive folder to your scan, but first make online-only files available offline. Avoid scanning C:\Windows and Program Files — DupSweep scans only the folders you choose, it does not specially lock the OS away.
