What is the Duplicate Photo Finder?
Duplicate Photo Finder is a free online tool that groups identical files and visually similar photos without uploading them.
It runs in your browser with difference hash, average hash, or both, plus an MD5 check for byte-identical copies.
WhatsApp forwards, iPhone bursts, HEIC plus JPG exports, and screenshot repeats often look the same but are not the same file. Visual hashing groups those copies. Keep the highest-resolution or largest file automatically, or pin the shot you want to save.
Limit matches to one folder, ignore tiny thumbnails, filter by filename, and export the delete list as text, CSV, or JSON. The browser cannot erase files on disk — you remove the listed copies in your file manager.

How to find duplicate photos online (without uploading)
- Drop photos or select a folder — JPG, PNG, WebP, HEIC, and GIF stay on your device.
- Use Similar photos with difference hash, or Exact duplicates for identical bytes. Set the threshold and choose which copy to keep.
- Pin any photo you want to force-keep, then export the delete list as text, CSV, or JSON.
The Duplicate Photo Finder is built for speed and privacy: find exact and similar photos in your browser — difference hash, keep the highest-resolution copy, folder scan, no upload.

Frequently asked questions
What is a duplicate photo finder?
A duplicate photo finder scans a set of images and groups files that match — either exactly (same bytes) or visually (same scene after resize, re-save, or light edits). Mytulify’s tool does this locally in your browser so photos never leave your device.
How is perceptual hashing different from exact duplicate detection?
Exact detection compares MD5 hashes — only byte-identical copies match. Difference hash and average hash fingerprint how a photo looks, so a resized WhatsApp save, a recompressed JPG, or a HEIC export can still group with the original.
Are my photos uploaded to Mytulify?
No. All analysis runs client-side. We do not store, transmit, or process your images on our servers. Close the tab and the scan data is gone.
What similarity threshold should I use?
Start at 5 with difference hash. Use 0–3 for near-identical copies, 8–12 for resized or recompressed saves, and higher only when you also want burst frames. Choose Both must agree if unrelated photos start grouping.
Does this delete files automatically?
No — browsers cannot delete files on your disk without permission. The tool marks safe-to-delete copies and lets you export a path list. You remove files manually in your file manager or gallery app.
Is this duplicate image finder free?
Yes. Unlimited scans on Mytulify’s free plan — no signup required. Pair it with our Duplicate File Finder for non-image duplicates across any file type.
