¿Qué es el Duplicate Photo Finder?
Duplicate Photo Finder is a free online tool that finds duplicate photos and visually similar images without uploading anything to a server.
It runs entirely in your browser using perceptual hashing (average hash), so your camera roll, WhatsApp saves, and screenshot folders stay on your device.
Unlike simple filename or size checks, perceptual hashing compares how a photo actually looks. That means it can group the same shot saved twice, a compressed copy, or a slightly resized version — common clutter on phones and laptops. Switch to exact mode when you only want byte-identical files.
Use the similarity slider to tune detection: low values catch near-identical duplicates; higher values group burst shots or lightly edited variants. Export a delete list when you are ready to clean up storage manually on your computer or phone.
How to find duplicate photos online (without uploading)
- Drop photos or select a folder — JPG, PNG, WebP, HEIC, and GIF are supported.
- Choose Similar photos (perceptual hash) or Exact duplicates (byte hash). Adjust the similarity threshold if needed.
- Review grouped thumbnails, note which file to keep in each set, and export the delete list as text or JSON.
The Duplicate Photo Finder is built for speed and privacy: find duplicate and similar photos locally with perceptual hashing — no upload, 100% private. Typical use cases include everyday personal tasks, student assignments, freelance deliverables, and quick checks at work when you cannot install desktop software. Because files and text often stay in your browser, it is a practical choice on shared or locked-down computers.
Benefits of using this free browser tool include zero install, instant results, unlimited use on the Free plan, and compatibility with phones, tablets, and laptops. Bookmark this page to return anytime, and pair it with related tools in the same category when your workflow needs multiple steps.

Preguntas frecuentes
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 file hashes — only byte-identical copies match. Perceptual hashing (aHash) fingerprints how an image looks, so resized WhatsApp forwards or re-exported JPGs 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 for a balanced scan. Use 0–3 for near-identical duplicates only; 8–12 if you also want resized or recompressed copies; go higher only if you accept broader visual matches (e.g. similar burst frames).
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.
