About Duplicate Media Finder

Have you copied the same photo or video to multiple folders over the years? The Duplicate Media Finder helps you recover gigabytes of wasted storage space. By scanning a target folder, it intelligently groups files that are exact duplicates in size and name. Because it runs 100% locally in your browser, you don't have to worry about uploading your private family photos or confidential work documents.

Features

• 100% Offline & Private: Scans local folders without uploading a single byte.
• Smart Duplication Detection: Groups files that are exact matches.
• Wasted Space Calculator: Shows you exactly how much storage you will get back.
• Smart Select: Automatically selects the extra copies while preserving the original.

1. Click the 'Select Folder to Scan' button and choose the directory you want to clean.
2. Allow the browser permission to read the file sizes.
3. Wait for the scan to finish and review the 'Duplicate Groups'.
4. Click 'Smart Select Copies' to automatically mark all redundant files.
5. Follow the file paths provided to manually delete the selected files from your computer.

Frequently Asked Questions

Does this upload my private photos to find duplicates?

Never. The tool uses standard browser File APIs to read the metadata (size, name, date) of the files locally. Nothing is sent over the internet.

How does it determine what is a duplicate?

For speed and efficiency in the browser, the tool groups files that have the exact same file size (down to the byte) and identical filenames. This catches 99% of accidental copies.

Why do I have to delete them manually?

Web browsers run in a secure 'sandbox' and are not allowed to physically delete files from your hard drive. This protects you from malicious websites. We show you exactly where the duplicates are so you can delete them yourself.
