Duplicate & Large File Finder

🔒

Your data is saved locally in this browser only — never sent anywhere.

Digital Declutter

Find duplicate and large files using File System Access API + SHA-256 hashing. Everything stays in your browser.

🗂️

Select a folder to scan. Files are hashed in-browser with SHA-256.
Nothing is sent anywhere. Large folders may take a while.

Requires Chrome/Edge 86+

Encrypted backup & restore

Everything this tool stores lives in this browser and nowhere else — that is the promise, and the risk. Clear your site data or switch machines and it is gone. Pro encrypts all of it under a passphrase you choose and hands you the file, so you can move it or keep it safe. It never leaves your device.
