Hide Secrets in Plain Sight

Securely embed files inside images. To the naked eye, it's just a picture. To those with the key, it's a digital vault. This allows discrete data transfer without drawing the attention that encrypted files might.

🔒 Client-Side Only & Zero Logging — You can trust this tool because it runs 100% in your browser. Your images, files, and secrets never leave your device. We do not collect, log, or store any user activity.

ℹ️ Security Recommendation: Default settings are potentially detectable. For secure transfer, you should use to randomize your key.

Hide File in Image

Upload a secret file and a cover image. The file will be losslessly encoded into the pixels.

1. Select Cover Image (PNG recommended)

2. Select Secret File

Frequently Asked Questions

How safe is this?

Steganography obscures the existence of secret data. However, using defaults makes your data detectable by anyone with this tool. Custom settings + Password Encryption makes it statistically impossible to crack.

Why use this / Best way to share?

Directly sending an encrypted file creates a record of transmission. To communicate without a trace, post the image to a public forum or image board. This "dead drop" strategy breaks the link between sender and receiver. To anyone else, it's just a cat photo.

Can I edit the image?

No. Any modification (resizing, compressing, filters) will destroy the hidden data. Ensure the platform you use hosts raw images and does not re-compress them (like Facebook/Instagram often do). Use file-sharing services or tech-focused community boards.

PNG or WebP?

PNG is the gold standard for lossless images. WebP is smaller but browser support for lossless writing varies. We verify WebP integrity before letting you download, so both are safe to use here.

How secure is the randomization?

Extremely. The custom alphabet scrambling allows for 64! combinations (approx. 10⁸⁹). For context, the number of atoms in the observable universe is estimated around 10⁸⁰. Brute-forcing the configuration without the key is statistically impossible.

How does it work?

We use a custom "Pixel Walker" algorithm. Instead of writing data linearly (which creates visible patterns), a deterministic random walk visits pixels in a unique, non-repeating sequence based on your seed. We then subtly modify the color values to match characters from your scrambled alphabet.
