GHOST PIXEL / ENCRYPTOR
2. Write Secret Message
The Ultimate Guide to Image Steganography
Ghost Pixel is a professional, privacy-first steganography tool that allows you to hide secret text messages inside ordinary images. Unlike encryption, which scrambles data, steganography hides the existence of the data itself.
How Does LSB Steganography Work?
LSB stands for **Least Significant Bit**. Digital images are made of pixels, and each pixel is made of 3 colors (Red, Green, Blue). Each color is a number from 0 to 255 (binary 8-bit).
- Ghost Pixel takes your secret text and converts it into binary (0s and 1s).
- It then replaces the very last bit of the pixel's color value with your message bit.
- cannot perceive the difference.
- The resulting image looks exactly like the original, but it carries a hidden payload.
Why Must I Use PNG Format?
Steganography is fragile. Formats like **JPG/JPEG** use 'lossy compression', meaning they delete some pixel data to save space. If you save a Ghost Pixel image as JPG, the compression will 'clean up' the noise, effectively **erasing your secret message**. PNG is a 'lossless' format, preserving every single bit exactly as it is.
Privacy & Security
Most online tools upload your images to a server to process them. Ghost Pixel runs 100% in your browser using JavaScript. Your photos and secrets never leave your device.
