Steganography

Client-SideOffline Ready

Hide secret messages inside ordinary images using LSB encoding. The image looks identical but carries a hidden payload.

Forces lossless PNG to preserve LSB bits

LSB Least Significant Bit Encoding

Injects message bits into the least-significant bit of RGB pixels. Produces zero human-perceptible distortion.

AES-256 Payload Encryption

Optionally wrap your hidden messages with AES-GCM encryption before encoding. Even if inspected, the payload is impenetrable without your password.

Lossless PNG Preservation

Forces lossless PNG container export to guarantee bit-level integrity against lossy JPEG re-compression.

Frequently Asked Questions

What is image steganography?
Steganography is the practice of concealing confidential information within an ordinary, non-suspicious carrier file, such as embedding UTF-8 text into an image canvas.
How does the LSB (Least Significant Bit) algorithm work?
LSB replaces the lowest bit of individual pixel color values (Red, Green, Blue) with bits from your secret message. Because the changes alter color channels by only 1 part in 255, the difference is completely invisible to the human eye.
Will JPEG compression destroy the hidden message?
Yes. Lossy formats like JPEG discard and alter pixel values. Steganographic images should always be saved and transmitted as lossless PNG files.
