Encrypt WhatsApp Messages

Lock a message with a password, then send the encrypted text or link in WhatsApp or any other chat.

AES-256 encryption
No data ever stored
Works offline once loaded
👋 New here? Type your message → set a password → press Encrypt. That's it — decrypting works the same way in reverse.
Your message ?Type or paste the message you want to lock with a password.
You can also drag & drop a .txt file here 0 / 20,000 characters
Scan a QR code ?Point your camera at a QR code someone sent you, or upload a screenshot/photo of one — the encrypted text will be read straight into the box above.

Camera access needs your permission, and works best on https:// pages.

Password ?Anyone who wants to unlock this text will need this exact password.
Confirm password
Password strength: —
Cipher: AES-256-GCM (authenticated) · Key derived with PBKDF2-SHA256 (60,000 iterations) using your browser's native encryption engine — fast, and far stronger against brute-force than a single hashing round. ?This is a real security upgrade, not just a label: deriving the encryption key takes real computational work, which makes large-scale password-guessing attacks dramatically slower.
Second password
Both passwords will be needed to unlock this message. Store them separately for maximum security.
Self-destruct ?After this time, the message can no longer be decrypted — even with the right password.
Password hint (optional) ?Shown to anyone with the encrypted text, before they enter a password. Never put the password itself here.
Overall protection: Basic Set a stronger password to improve this score.

Result
Cover image (optional)

Leave empty and we'll auto-generate a suitable image. PNG output only — JPEG, WhatsApp, and other apps that recompress images will destroy the hidden data, so share the downloaded PNG file directly.

About this generator

WhatsApp already encrypts messages in transit, but a message stays readable on the phones and backups of everyone in the chat. If you want a message that only a person with the password can read, encrypt it here first. Send the encrypted text or the share link in WhatsApp, then tell your friend the password in another way. The Share button can open WhatsApp with the link ready to send.

How to use this tool

Frequently asked questions

Why encrypt a message that WhatsApp already encrypts?
WhatsApp protects messages while they travel. A password-locked message also stays unreadable in backups, screenshots of the chat and on shared phones.
Can my friend open it on their phone?
Yes. They open the link or paste the text on the Decrypt tab and enter the password.
Does WhatsApp see my password?
No. The password is never sent, and the link keeps the message after the # sign.
