Find the keepers.
Clear the clutter.

Request access with your email at dupix.in/beta and confirm the address. We approve each photographer by hand and email you when you’re in. During the beta you get every Studio feature free for 30 days, and we’d love your feedback. The prices on this page apply after the beta.

No. Dupix opens the folder you choose straight from your disk and does every comparison inside your browser, on your own machine. No photo, thumbnail or result is sent to us or to anyone else. You can even pull out the network cable mid-scan and it carries on.

Never. Photos you mark are moved into a folder called “_To delete (Dupix)” beside your originals, with a list of where each one came from. You look through it in Finder or File Explorer and delete it yourself when you're happy. Changed your mind? Put them back returns every file to its original folder in one click.

Yes. Dupix reads RAW from Canon, Nikon, Sony, Fujifilm, Olympus, Panasonic and Pentax, plus DNG, alongside JPEG, PNG, WebP, AVIF, HEIC (iPhone), TIFF (8 and 16 bit) and BMP. A RAW and its matching JPEG are treated as one photo, so they're always kept or moved together. A file Dupix can't open (empty, damaged, or a type such as GIF or PSD) is listed with the reason, never silently skipped.

Scanning works in Chrome, Edge, Firefox and Safari on a computer. Moving marked photos into the review folder for you needs Chrome or Edge, because only those let a web page write back to a folder you picked. In the others you still get the full results, the CSV list and, on Studio, the Lightroom export.

Yes, on Studio and during the free trial. Dupix writes an .xmp sidecar next to each photo: the best frame of a burst gets two stars, everything else you keep gets one star, and anything you marked is flagged rejected and labelled red. Import the folder and your decisions are already there. The same sidecars work in Capture One. Trial exports also carry a “Culled with Dupix” keyword.

Nothing at all. Your photos and any review folders are files on your own drive and stay exactly as they are. Dupix just stops scanning new folders until you buy again.

Yes. Press Edit photos on the start screen to go straight to the editor, or edit the photos you keep after a scan. The editor has light and colour, Pick white balance, curves, fine detail, haze removal, noise reduction, effects, a brush, selective points, healing, lens blur, perspective, crop with ready-made ratios (4:5, 9:16, 4×6, A4 and more), zoom, looks and presets, and copying one edit to a whole burst. Edits are saved as settings and your originals are never changed; you export edited JPEGs (with an optional watermark) into a folder next to your photos. In the browser Dupix edits the JPEG, or the JPEG preview stored inside a RAW file, so for full RAW quality hand the edits on to Lightroom with the XMP export.

Your first 300 photos, with no card. The trial finds duplicates, look-alikes, the best burst frames and closed eyes, and moves rejects to a review folder, just like Pro. You can also try the Studio tools: Lightroom export, Find people and Line up cameras, with a small “Culled with Dupix” mark on what they export. Side-by-side compare, the cleanup list (CSV) and pause-and-resume come with Pro and Studio.

No. Every plan is prepaid and simply ends. There is no auto-renewal, no stored mandate and no cancellation to remember. We email you before your plan runs out, and you buy again only if you want to.

Yes. It counts blinks across every face it can see and, in a burst, keeps the frame where the fewest people blinked, ideally nobody. The labels say it plainly: “2 of 5 blinking” or “Eyes open 5/5”. Faces in very large groups can be too small for the quick check, so tick Check every face in large group photos before scanning a wedding or team group.

Dupix turns each face into a short list of numbers on your computer and groups faces whose numbers are close. You confirm the matches, name the person, then copy their photos into a folder or download a list. Find people is part of Studio, and you can try it in the free trial. Nothing is uploaded, faces are never saved, and everything is forgotten when you close the tab. It suggests and you decide: makeup, profiles and small faces can fool it.

No. With Judge sharpness on the subject ticked (it is by default), Dupix finds the eyes of the main face, or the animal or bird, and measures sharpness there, so a frame with crisp leaves and a soft bird doesn't win. When a subject can't be found in every frame of a burst, it falls back to the whole photo, and the burst tells you which it used.

Yes. Scan both cards together and press Line up cameras (part of Studio, and in the free trial). Dupix finds the moments both of you caught, works out the gap between the clocks (to within a second or two), and shows you those moments so you can check. Adjust it if you like, then copy everything into one folder numbered in true shooting order. Your original files are not changed. Two cameras of the same model are told apart by serial number.

Yes. Renamed copies are found by comparing the contents, not the names. A copy whose keywords, rating or date were changed is matched on its picture data, so the different metadata doesn’t hide it. Exports, crops and black-and-white versions of a shot are matched by the camera’s capture time and kept together under Edited versions; Dupix never marks those for deletion. If an export’s metadata was stripped, Dupix can only match it by how it looks.

Tens of thousands of photos in one pass, including subfolders. On Pro and Studio, Dupix remembers how far it got, so you can close the tab mid-scan and carry on later from the same photo.

Every suggestion arrives as a group with the reason written under each photo, and nothing moves until you press Move. Click any photo to switch it between keep and delete, or use Keep all on a group. If something slips through anyway, Put them back returns every file.

Mostly it depends on your computer and where the photos live: an internal SSD is quickest, a USB hard drive or network drive slower. Dupix shows live progress, you can pause and carry on later, and switching off the closed-eye check makes scans faster for shoots without people.

Yes — any folder your computer can open, including external drives and memory cards. Network drives work too, just more slowly, because every photo is read over the network.
