Image Steganography Studio
Cryptography & SecurityHide encrypted secret messages inside PNG images using LSB pixel manipulation and AES-GCM 256-bit encryption. Encode and decode steganographic payloads — fully in-browser.
100% Client-Side In-Browser Steganography
Your carrier images and secret messages are processed strictly inside your device's memory using HTML5 Canvas pixel manipulation and Web Cryptography API (AES-GCM 256-bit). No data is ever uploaded to any cloud server.

What is Image Steganography Studio?
Conceal confidential messages, private keys, or passwords inside ordinary digital images using Least Significant Bit (LSB) steganography combined with optional AES-GCM 256-bit encryption. 100% in-browser processing with zero pixel degradation.
How to use Image Steganography Studio
3 simple steps to complete your task directly in your browser:
Choose Encode or Decode Mode
Select Encode to embed a hidden message into a carrier image, or Decode to extract a secret message from a previously encoded PNG image.
Upload Image & Enter Secret
Upload a clean PNG or JPG image, write your message, and optionally specify an encryption password for military-grade dual-layer protection.
Download Lossless Stego PNG
The engine embeds the secret into the color channels at the bit level and exports a visually indistinguishable lossless PNG image.
