Hidden Message:
Secure Hiding
Messages are hidden in the least significant bits of image pixels, making them undetectable to the human eye.
Password Protection
Add an extra layer of security by encrypting your message with a password.
Local Processing
All operations happen locally in your browser. No data is ever sent to any server.
Message Hidden Successfully!
Your message has been successfully hidden in the image. The image looks identical but contains your secret message.
Remember: To decode the message, upload this modified image in the "Decode" section.
Anyone with this image and password (if used) can extract the hidden message.

π What is Advanced Image Steganography?
Image steganography is a smart digital technique that lets you hide secret information inside an image without changing how it looks. Instead of visible encryption or locked files, steganography conceals data in plain sight β blending your hidden message directly into the image pixels.
π§ How Does It Work?
Every digital image is made up of millions of tiny colored dots called pixels.
Each pixel has color values (R, G, B), and each value is stored in binary.
By replacing just the last bit (Least Significant Bit) of these binary numbers with the bits of your message, the image looks exactly the same to the naked eye β but now carries a hidden message inside.
Our tool, StegaCrypt, applies this LSB steganography method combined with optional XOR-based password encryption.
This dual system ensures that:
Only you (or someone with the correct password) can decrypt it.
The image itself remains visually unchanged.
Everything happens locally in your browser β no data is uploaded anywhere.
π§ Step-by-Step: How to Hide a Message in an Image
πΌοΈ Step 1 β Upload or Paste an Image
Drag & drop an image, paste it from the clipboard, or use a URL. The tool supports PNG, JPG, and WebP.
π¬ Step 2 β Write Your Secret Message
Type the text you want to hide. The tool will show how many characters your image can hold (based on resolution).
π Step 3 β Add a Password (Optional)
For extra protection, add a password. This encrypts your message using XOR encryption before itβs hidden.

βοΈ Step 4 β Hide Message
Click βHide Messageβ, and the tool will encode your message into the image using Least Significant Bit Steganography.
π₯ Step 5 β Download Your New Image
Save your modified image. It looks the same as before β but secretly carries your text inside.

π§© How to Decode a Hidden Message
Open the Decode tab.
Upload or paste the stego image.
Enter the password if it was encrypted.
Click βExtract Messageβ β your hidden message appears instantly.
