How to Remove Duplicate Images from a Folder on Windows (5 Methods)
Duplicate images can easily clutter your folders, take up storage space and make file management annoying. Thus, removing them all is essential. This guide will teach you how to find and remove duplicate images from folder both manually and automatically, so you can decide which one works best for you.
Why Duplicate Images Pile Up (and What They Cost You)
We can tell you that most duplicates are not made on purpose. They just sneak in through:
- Repeated phone or camera backups to the same folder
- Downloading the same image more than once (you will see names like photo (1).jpg)
- Copying folders between drives “just to be preventive from data loss”
- Editing applications that generally save a copy instead of overwriting
- Cloud sync tools that generally create conflict copies
The damage adds up silently in the background. A library of 10K photos at 4 MB each is about 40 GB, and even 15% duplicates wastes around 6 GB. And as a result of this, backups take longer, searching gets messy, and you can never be sure which copy is the original.
Problems Caused by Duplicate Images
Keeping duplicate images may lead to several issues including:
- They consume unnecessary storage space
- They contribute to slower system performance
- It becomes challenging to find original files
- Messy and unorganized folders
- Increased backup size
Deleting duplicate images will guarantee effective file management and efficiency of the system.
Method 1: Remove Duplicates Manually in File Explorer
This method is best for folders having fewer than 100 images.
Step by Step Guide
- Open the folder in “File Explorer” and then switch to the “Details” view.
- Now, right click the column header and add “Size” and “Date taken”.
- Sort by Size. Identical images sit next to each other.
- Now, open or preview the neighbors to confirm they match. Then, delete the extras.
- Finally, empty the Recycle Bin.
Limitations
- This method only works when the duplicates are the same size
- It generally misses copies that are saved in a different format or compression
- It gets tedious fast
Method 2: Find Duplicate Images with PowerShell (Free)
This method is ideal for techies who want exact matches without installing anything.
Step by Step Guide
- Right click “Start” and open “Windows Terminal” or “PowerShell”.
- Now, paste the script below. Just change the folder path to yours.
- Press “Enter” and wait. Large folders may take a few minutes.
Get-ChildItem "C:\Photos" -Recurse -File -Include *.jpg,*.jpeg,*.png,*.heic |
Get-FileHash -Algorithm SHA256 |
Group-Object Hash |
Where-Object { $_.Count -gt 1 } |
ForEach-Object { $_.Group | Select-Object Hash, Path }Limitations
- It finds exact matches only
- You still need to delete files by hand
Method 3: Use a Free Duplicate Finder
This method is best for one off cleanups where you need a visual interface and do not want to pay.
A few well known free options
- dupeGuru: it is open source, with a picture mode that may find similar images.
- Czkawka: it is open source and fast, with exact and similar image scanning.
- AllDup: it is freeware with many search options (content, name, size).
The workflow is generally the same everywhere. You just need to add your folder. Select content based matching. Scan and preview the results. Mark the extras and send them to the Recycle Bin.
