Duplicate Photo Finder finds and safely deletes duplicates and similar photos on your Windows PC. It intelligently detects the best copy in each group to keep.
File Explorer has no duplicate search. It can sort a folder by name, size or date, and that is where most people start.
In Details view, sort by size and look for entries with the same number.
Duplicate Photo Finder checks image content in every location you add.
Drag photos or folders into the window, click the Add Folder button, click Scan Computer or choose a drive. System folders are skipped.
Choose Exact Match for byte-identical copies or Similar Match for shots with small differences. Click Scan. Similar photos appear as the scan finds them.
Each duplicate group marks the suggested best photo with a green frame. Configure the rules in Selection Assistant. Other photos are marked for deletion.
Click the Delete Marked button. Worse photos move to the Windows Recycle Bin and can be restored if needed.
The top bar counts Space to be Saved before deletion. Most of it hides in phone backups imported twice and in a photo library stored both on the PC and on a USB stick.
One photo per set wears a green border. The app prefers the file with the most pixels, then the crisper shot, the bigger file and the more recent one. A clean original beats the blurry burst frame taken half a second later.
Deleted photos go to the Windows Recycle Bin. Every group keeps at least one file, so a whole set cannot vanish. A photo the app failed to read is never marked on its own. Windows has no Recycle Bin on a network share, and the app warns you before those files are deleted for good.
The whole scan runs on your processor, so it needs neither a graphics card nor a fast PC. Thumbnails are cached between runs, making a second pass over the same library quicker.
Exact Match compares SHA-256 checksums, so only byte-identical files group together. Similar Match builds a perceptual hash of each picture and groups shots that still look alike after resizing or recompression. Groups appear on screen while the scan is running.
The app measures focus with a variance-of-Laplacian blur score. Find Blurry Photos lists out-of-focus shots below a threshold set with a slider, even without duplicates.
What to Find has three modes. Photos are compared visually. Photos + Video adds clips such as MP4, MOV and MKV as exact copies, and All Files does the same for installers, archives and documents.
Point it at one folder, or drop several folders or photos at once. Selected folders are saved for future scans. Scan Computer scans selected drives or all of them.
Accuracy has Medium, High and Custom presets. The Matching Level slider sets how close two shots must be, and Bitmap Size trades speed for detail. Reset Default Settings restores the defaults.
Auto Mark ticks every copy except the keeper in each group. Selection Assistant offers four rules. Keep Newest and Keep Oldest go by date, while Keep Largest and Keep Highest Resolution go by size. Review in large icons, small icons or a table, with EXIF in the Preview panel.
Comparison depth depends on the format. Check the tab for your files before a big cleanup.
Camera-roll images, downloads and edited versions. A smaller or recompressed JPG sits beside its original.
Screenshots and scans. A PNG made from a JPG still pairs with it because the content counts, not the bytes.
TIFF comes from scanners and print work, WebP from images saved off websites. A WebP copy of a photo you keep as JPG shows up as a duplicate.
Old web graphics and memes that got saved more than once.
When a RAW file, its JPEG export and a phone copy sit in one group, look at the framed photo before you delete. If you edit from RAW, move the keeper to the RAW file by hand.
Canon CR2, CR3 and CRW. Nikon NEF and NRW. Sony ARW, SRF and SR2.
RAF (Fujifilm), ORF (Olympus), RW2 (Panasonic), PEF (Pentax) and SRW (Samsung).
DNG (Adobe, and the RAW mode of many phones). Leica RAW and RWL. IIQ (Phase One). 3FR and FFF (Hasselblad).
MRW (Minolta), DCR and KDC (Kodak), MOS (Leaf), ERF (Epson) and X3F (Sigma). That makes 25 RAW extensions in total.
The default camera format on iPhones and many newer Android phones. Byte-for-byte twins are caught, and each file gets a sharpness rating.
A HEIC photo and the JPG your iPhone made from it are not paired yet. Need that? Convert the HEIC set to JPG first, then run the search again.
Windows opens HEIC through the HEIF and HEVC extensions from Microsoft. When they are missing, the app skips HEIC files and finishes the rest of the scan.
The scan never enters Windows or Program Files. It also skips ProgramData and AppData, so pictures cached by apps there stay out of the results.
Camera rolls fill with burst frames and screenshots. The same sunset frame or portrait is often saved 10+ times. Run the duplicate photo cleaner to free storage space. For a full shoot with blinks, missed focus and near-misses beyond simple duplicates, ai photo culling software shortlists the keepers first.
A shoot leaves series of repeated RAW frames plus JPEG exports of the same shots. Keep the best frame of each series and clear the rest.
Copied photos from an old drive, then added your current phone backup? The scan reads every source on one or several drives and finds overlaps.
Prefer installing apps through the Microsoft Store? You can also get Duplicate Photo Finder Software on Microsoft Store.
The free version is not a demo with hidden results. It scans, groups and marks everything it finds, then stops after 15 deletions per session.
