How It Works

Four steps to a cleaner photo library — every comparison runs on your device, in your browser.

1

Choose Your Photos

Pick a folder on desktop, or select photos directly on phone and tablet. The app reads them right there — nothing is uploaded anywhere.

2

Automatic Scan

Exact copies show up in seconds. The app keeps comparing for re-encoded, resized, and visually similar photos while you review what's already found.

3

Review Groups

Every group of duplicates comes with a pre-selected best shot, picked by sharpness, exposure, and resolution. One click keeps the best in every group.

4

Clean Up Safely

Duplicates move to a review folder by default — fully reversible. Permanent deletion is available, but only as an explicit, confirmed choice.

Privacy Guarantee

  • Every comparison runs locally in your browser — zero photos ever leave your machine
  • Similar-shot detection downloads a small one-time recognition model, then caches it locally
  • Disconnect your internet after the page loads — scanning and cleanup keep working offline

Exact Copies vs. Similar Photos

  • Identical copies: the exact same file, byte for byte — even if renamed or moved
  • Same photo, different file: re-saved, resized, or lightly edited — visually the same picture
  • Burst shots: several frames from the same moment — handled conservatively since each frame may be worth keeping
  • Very similar: visually near-identical photos that aren't burst frames

Frequently Asked Questions

Are my photos uploaded anywhere? +
No. Every comparison happens on your device, inside your browser. Your photos never leave your machine — you can disconnect your internet after the page loads and the app keeps working.
What's the difference between exact copies and similar photos? +
Identical copies are byte-for-byte the same file, even if renamed. "Same photo, different file" means it was re-saved, resized, or lightly edited. "Very similar" and "Burst shots" catch photos that look alike but aren't pixel-identical, like several frames from the same moment.
Will this delete my photos? +
Not by default. The default action moves duplicates into a _Duplicates_Review_ folder inside your scanned folder, so nothing is lost. Permanent deletion is available only as an explicit, confirmed opt-in.
How does the best-shot suggestion work? +
Within each group, the app scores every photo on sharpness, exposure, resolution, and file size, then pre-selects the best one to keep. You can always change the pick.
Does this work with RAW and HEIC photos? +
Yes. The app reads the preview image already embedded inside RAW and HEIC files by your camera or phone. Exact-copy detection always works regardless of format.
Which browsers are supported? +
Scanning works everywhere. Moving or deleting files directly requires a Chromium-based browser (Chrome, Edge, Brave, Opera). Firefox and Safari get a guided cleanup checklist instead.
