Duplicate Images Finder Freeware, Portable – Windows
It is pretty common to have duplicate images if you have a huge number of images or photos within your collection. Removing the duplicate images manually from such a large collection is not impossible, but it will spend more than just a couple of days. With an automatic duplicate images finder, you can shorten the time of cleaning up your photo collection from any duplicate.
Previously I used the picture comparison feature of FastStone Image Viewer to compare up to four images at once, but it still requires to find the duplicate images manually and then compare the images in a side-by-side environment. It is a pretty time consuming. Hence, I search for a duplicate images finder freeware and my choice falls into this one.
ImgSearch is a portable freeware that lets you to easily find duplicate images in as many folders as you want to. No more manual crawling into numerous folders as you may have done previously. It allows you to find image duplicates within a few clicks.
The images supported are JPG, BMP, ICO, CUR, WMF, EMF, PNG, PCX, GIF.
How to find duplicate images using ImgSearch:
- Click the add button or press Ctrl + +.

- Click the Compare button or press Ctrl + Enter.
- A new window pops up with several scanning options. Configure or let them that way and click the Start button to begin the scanning process immediately.

A few notes for this freeware:

- The picture information, which is located right above the preview column, includes the size and dimension of the images. If the similarity level of the images is 100%, the color of this information section turns to green. If you see other colors, it means the images compared isn’t completely similar.
- If the color of the picture information is green, you can instantly mark the duplicate images without even viewing the images.
