Airsweep · duplicate photo cleaner

Years of photos. One copy of each.

Airsweep finds the same picture saved twice — in phone backups, camera imports, Google Takeout and old-PC copies across folders and drives — plus resized and converted versions and burst shots. It keeps the best one and moves the rest to the Recycle Bin, with undo. Fast on tens of thousands of photos, fully offline, no account, no subscription.
여러 폴더와 외장 드라이브에 흩어진 중복·비슷한 사진을 찾아 가장 좋은 것만 남깁니다. 휴지통으로 옮기고 되돌릴 수 있습니다. 오프라인, 계정·구독 없음.

Airsweep results: groups of duplicates on the left, a burst of similar shots with the sharpest frame kept

Exact copies

Byte-for-byte duplicates in any folder or drive, photos and videos.

Same photo, other size

Resized, re-saved and JPEG/HEIC/PNG versions — every match checked pixel by pixel, so different screenshots are never mixed up.

Bursts and retakes

Shown side by side with the sharpest frame marked. Never selected for you.

Safe by design

Files go to the Recycle Bin or a folder you pick, each group keeps one, files changed since the scan are skipped, and you can undo.

Questions

Does Airsweep delete anything on its own?
No. You review every group; nothing in a group of similar shots is selected for you. Cleaning moves files to the Recycle Bin or a folder you choose, and the last clean can be undone.
How fast is it?
It reads only what it needs: a small preview of each photo and full hashes only where sizes collide. Rescanning the same library takes seconds because Airsweep remembers what it already read.
Which files?
JPEG, PNG, HEIC/HEIF (with Microsoft’s HEIF extension), WebP, TIFF, GIF, BMP and common camera RAW files (through their preview); videos are matched as exact copies.
