Image Steganography (Hide Text in Image)

About Image Steganography (Hide Text in Image)

Securely hide a secret text message inside any PNG image using LSB (least-significant-bit) steganography. The output image looks visually identical to the original but carries your encoded message. Optional AES-256 password layer so only the right person can decode. Then upload a stego-image later to extract the message. 100% client-side — your message and image never touch a server.

How to Use Image Steganography (Hide Text in Image)

Securely hide secret text messages inside PNG images using LSB steganography and optional AES-256 encryption.

1. 1

   Upload your source PNG image

   Select the PNG image file you want to use as the carrier for your secret message. The tool processes everything locally in your browser for maximum privacy.

2. 2

   Enter your secret text message

3. 3

   Set an optional encryption password

   Add an extra layer of security by entering an AES-256 password. This ensures that only users with the correct key can extract and read the hidden text.

4. 4

   Encode and download the stego-image

   Click the encode button to embed the text into the image's least-significant bits. Download the resulting file, which will look identical to your original image.

5. 5

   Extract hidden text from an image

   To reveal a message, upload a previously encoded stego-image and enter the password if one was used. The tool will instantly decrypt and display the hidden text.
