Only PNG files retain hidden dataEnter the password this message was encoded with.
How It Works
- Encryption: Your message is encrypted with AES-GCM (256-bit), key derived via PBKDF2 with 100,000 iterations. Without the password, the data is mathematically irrecoverable.
- Steganography: The encrypted bytes are hidden in the least-significant bits of each pixel's RGB channels. The image looks identical to the human eye.
- Zero-knowledge: All processing happens in your browser. No data is transmitted anywhere.
The Golden Rules
- Always save and share as PNG. Never convert to JPG, WEBP, or AVIF.
- Never screenshot the encoded image — screenshots re-compress pixels and destroy the hidden data.
- Do not edit the PNG in other software after encoding.
Sending Safely
- On WhatsApp, Telegram, Discord — send as "File" or "Document", not as a Photo. Photos get compressed automatically.
- Email attachments preserve PNG files correctly.
- Security tip: Send the image and the password via different channels.
About Vör
- In Norse mythology, Vör is the goddess of awareness — "so wise and searching that nothing can be concealed from her." Her name means aware or careful.
- This tool is named in her honour: a vault that hides information in plain sight, revealing it only to those with the awareness to look — and a key.
