Find duplicate files by scanning directories and comparing SHA-256 hashes. All processing happens in your browser.
100% Client-Side Processing: All file scanning and hashing happens in your browser. No files are uploaded to any server.
How it works: Select a directory, and the tool will scan all files, compute SHA-256 hashes, and group files with identical hashes as duplicates.
Delete Files: You can delete duplicate files directly from this tool, but only if you selected them using the "Select Folder" button (not the "Select Files" fallback). Deletion requires confirmation and cannot be undone.
