About Image Steganography Tool
The Image Steganography Tool hides secret text inside PNG images using least-significant-bit (LSB) encoding, with optional AES-GCM password encryption for added confidentiality. Extract hidden text just as easily, and watch the capacity indicator to know how much text your image can hold. Everything runs locally in your browser.

Frequently Asked Questions
Why PNG only?
PNG is lossless, so hidden data survives intact. JPEG's lossy compression would corrupt the hidden message.
Is steganography secure?
LSB encoding is detectable by analysis. For real confidentiality, use the password-based AES-GCM encryption option.
