Files never leave your device

What is Duplicate File Finder?
This duplicate file finder scans your selected files and identifies exact duplicates by computing SHA-256 hashes privately on your device. No files are uploaded. Group duplicates, review them side-by-side, and decide which copies to keep.
How to use
- Drag and drop files or select a folder of files you want to scan for duplicates.
- Wait for the tool to compute SHA-256 hashes for each file and group identical files together.
- Review the duplicate groups, compare file details (name, size, date), and export the report as CSV for cleanup planning.
