PictureEcho is a duplicate photo finder for Windows and Mac. It scans your folders or photo libraries (including Adobe Lightroom and Apple Photos), finds exact duplicates and visually similar photos, and lets you review and remove them in bulk to free up space.
PictureEcho offers a trial so you can try the photo deduplication tool before buying. In the free trial, it deletes visually similar or exact duplicate pictures from 10 image-groups. After that, a license is required for continued use.
Add one or more folders (or choose a detected library like Lightroom or Photos), pick Similar or Exact scan mode, then run the scan. PictureEcho groups duplicates and similar images so you can select which to keep and which to delete or move to the Recycle Bin.
Exact Mode finds files that are byte-for-byte identical (same file hash). Similar Mode finds photos that look alike (resized, edited, or re-saved) using perceptual hashing and image comparison. Use exact for true duplicates; use similar for near-duplicates and variants.
PictureEcho supports common and professional formats: JPEG, PNG, WebP, GIF, BMP, TIFF, HEIC/HEIF, and major RAW formats (e.g. CR2, CR3, NEF, ARW, DNG, ORF, RW2, PEF, SRW, RAF). Both similar and exact scans use the same format list; similar scan requires successful image decode for perceptual comparison.
Yes. PictureEcho can detect and scan Adobe Lightroom Classic (catalogs), Lightroom CC, and Apple Photos (Photos Library). You can use the default library paths or choose a custom catalog or library. PictureEcho reads the library's file list and then finds duplicates and similar images among those files.
Yes. PictureEcho is a duplicate photo finder for Windows (Windows 11 and 10) and macOS (Intel and Apple Silicon). Download for Windows or the Mac DMG from our website.
On Mac, PictureEcho requires macOS 10.15 (Catalina) or later and runs on both Intel and Apple Silicon. On Windows, use a current supported Windows version (e.g. Windows 10/11). The installer may install or use the WebView2 runtime if needed.
The Mac build is signed and notarized by the developer. macOS Gatekeeper will accept it for installation without marking it as from an "unidentified developer," so it's safe to install from the official download or store.
No. PictureEcho only suggests groups of duplicates or similar photos. You choose which images to remove. Deleted files go to the Recycle Bin (Windows) or Trash (Mac) unless you use a permanent-delete option, so you can recover them if needed.
Yes. You can set excluded paths (e.g. system or backup folders) so the software skips them during folder scans. This helps focus on your real photo libraries and avoids scanning places you don't want.
On Windows and Mac, PictureEcho skips files that are cloud-only (e.g. OneDrive or iCloud placeholders that aren't fully downloaded). The app only compares photos that are stored locally so results are accurate and the scan stays fast.
In Similar mode, a similarity threshold (e.g. 1–13) controls how strict the match is. Lower = stricter (more alike); higher = looser (more "similar" pairs). You can adjust it before scanning to balance between catching near-duplicates and avoiding false matches.
Scan results and settings are stored locally on your computer (e.g. in the app's data folder). Your photos are never uploaded to our servers; the duplicate picture finder runs entirely on your machine.
Use Check for updates in the app. It will point you to the latest version on the website (or to the store page if you installed from the Mac or Windows Store). We recommend keeping the app updated for the best experience and security.
Yes. Add the folders on your external drive or network share as scan sources. As long as the drive is mounted and the files are accessible, PictureEcho can scan them. For network locations, scanning may be slower than for a local disk.
You can manually choose the catalog or library folder. In the library-scan flow, use the option to set a custom path to your Lightroom catalog (.lrcat), Lightroom CC folder, or Photos Library (.photoslibrary). The app will then use that path for the scan.
Yes. PictureEcho is built to handle large folders and libraries. Scans can be cancelled and resumed by running a new scan. Similarity is computed in batches and progress is shown, so even big collections are manageable.
PictureEcho offers similar and exact modes, support for RAW and HEIC, and direct integration with Lightroom and Apple Photos. You keep full control over what gets deleted, and all processing stays on your device for privacy.
