Features

Secure Hiding

Hide text messages within the pixels of an image using Least Significant Bit (LSB) steganography.

Optional Encryption

Add a password/key to encrypt your message before hiding it for an extra layer of security.

Invisible Changes

The encoded image looks identical to the original to the naked eye.

Lossless Output

Exports as PNG to ensure the hidden data is preserved (compression would destroy the message).

About Image Steganography

This Image Steganography tool allows you to covertly hide text messages inside standard image files without changing their visual appearance. It uses a technique called Least Significant Bit (LSB) encoding, where the last bit of pixel color data is modified to store your binary message. Because the change is so subtle (changing a color value by 1/255), it is impossible to detect with the human eye. You can also add a password to encrypt your message, ensuring that only someone with the key can reveal the hidden contents.

How to Use Image Steganography

Upload Image

Select a high-quality image (PNG or JPG) to use as a cover.

Enter Message

Type the secret text you want to hide. You can also set an optional password.

Encode & Download

Click 'Hide Message' to process the image, then download the resulting PNG file.

Decode

To read a message, upload the encoded image in the 'Decode' tab and enter the password if used.
