Works on any device — desktop, tablet, mobile. No installation needed. Just open and use.
If you've ever:
- Imported passwords from multiple browsers (Chrome, Firefox, Edge...)
- Switched between password managers (Bitwarden, LastPass, 1Password...)
- Re-imported your vault CSV/JSON and got duplicate entries
- Spent hours manually deleting duplicates
PwdCleaner solves this in one click. It finds exact duplicates, removes extras, and exports clean data back to your password manager's format.

- AES-256-GCM Encryption — Encrypt vault files with your passphrase (PBKDF2 200k iterations)
