Is my file sent to a server?

No. Only the model weights are downloaded. Your images and text are processed inside your browser.

Why is the first run slow?

The model has to download once. After that it loads from the browser cache in a few seconds.

My computer has no WebGPU. Does it still work?

Yes. The model runs on the CPU in a background worker. It is slower but the page stays responsive, and you can cancel at any time.

Are my files uploaded?

No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.

Is it free? Are there limits or watermarks?

Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.

Does it work offline?

Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.

Similar Photo Finder

Find duplicate and look-alike photos in a big batch, keep the best one and download the rest cleaned up.

Free, no uploads, no sign-up. Runs 100% in your browser.

How Similar Photo Finder works

The model runs with Transformers.js and ONNX Runtime inside a background worker, so the page never freezes. It downloads once from the Hugging Face model hub and is then cached by your browser, so it works offline. With WebGPU it uses your graphics card, without it the CPU. Your files are never uploaded. AI mode compares CLIP image embeddings, so burst shots of the same scene are grouped. Fingerprint mode uses a perceptual hash and needs no download.

Input: JPG, PNG, WEBP, HEIC. Output: ZIP, CSV.

How to use Similar Photo Finder

Drop a folder of photos.
Choose AI or Fingerprint and set the strictness.
Press Find similar photos and review each group.
Keep the largest in each group, then download the kept photos as a ZIP.

Tips

Fingerprint mode is instant and great for resized or re-saved copies.
