KeePass .kdbx Viewer & Converter
A KeePass database viewer powered by the kdbxweb library. Drop a .kdbx file (KDBX3 or KDBX4), enter the master password, and the database is decrypted in your browser. Browse and search entries, reveal individual passwords, and export the vault to CSV or JSON for migration to another manager. The file and its decrypted contents never leave your device.
How to use
Drag your KeePass database file onto the drop zone or click to browse.
Type the master password you use in KeePass. If your vault also uses a key file, attach it.
The decrypted entries appear in a table. Use the search box to find specific entries; click rows to reveal passwords.
Choose KeePass CSV or Bitwarden JSON to migrate to another manager.
Open your KeePass vault in any browser — no installation, no upload, no server

🔒 Privacy
- The .kdbx file is parsed and decrypted entirely in your browser via the kdbxweb library.
- Your master password is used locally to derive the key (Argon2 / AES-KDF as the database specifies). It is never transmitted anywhere.
- The decrypted entries live only in your browser tab. Close the tab — they are gone.
- For maximum trust, load this page once with a network connection, then disconnect before opening your vault.
Features
FAQ
Is my .kdbx uploaded?
No. The file is read by JavaScript in your browser. kdbxweb decrypts it locally using your master password — Argon2 / AES-KDF computation happens on your CPU. Nothing leaves your device.
Does this support KDBX4?
Yes. Both KDBX3 (KeePass 2.0+) and KDBX4 (KeePass 2.35+, with Argon2 KDF and ChaCha20 stream) are supported.
My password is correct but it fails. Why?
Most commonly: a key file is required and not attached. Check whether your KeePass setup uses a key file alongside the master password. Less commonly, a corrupted file.
Can I edit or save changes?
Not in this version — it is a read-only viewer for migration and inspection. Edit your vault in the KeePass app and re-import to migrate.
Can I open KeePass 1.x databases?
No. The legacy KDB format (KeePass 1.x) is not supported. KeePass 1.x can export to KeePass 2.x format from the desktop app.
How safe is it to enter my master password here?
The page is open-source code you can inspect via View Source. The master password is held only in JavaScript memory and discarded when the tab closes. For maximum trust, run the page offline after first load.
