🔐 Secure Steganography Tool – Hide Text in Images with AES Encryption

Secure Steganography Tool is an advanced, browser-based tool that uses the Least Significant Bit (LSB) technique to hide secret messages inside images. It offers optional AES-GCM encryption for password-protected text within PNG files, ensuring complete privacy with no server-side processing. It's a fast, free, and secure way to encode and decode hidden messages.

🔐 Encode Message – Hide Text in PNG

Select Image: Text to Hide: Encryption Password (Optional):

* For best results, use PNG images. Text size is limited by image dimensions.

🔓 Decode Message – Extract Hidden Text from Image

Select Encoded Image: Decryption Password (if used):

Revealed Message:

No message decoded yet.

🛠️ How to Use Secure Steganography Tool (Step-by-Step)

To Hide (Encode) a Message:

Select a PNG image using the Select Image input in the Encode Message section.
Enter the secret text you wish to embed.
Optionally add a password to encrypt the message with AES-GCM.
Click Hide Message and wait for processing to complete.
Click Download Encoded Image to save your secure image.

To Reveal (Decode) a Message:

Upload the encoded PNG using the Select Encoded Image option in the Decode Message section.
Enter the decryption password if one was used during encoding.
Click Reveal Message to extract the hidden text.

⚠️ Important Notes for Safe Steganography

Use PNG Images: Lossless formats like PNG preserve hidden data better than JPEG or WebP.
Password Encryption is Optional: Enable AES encryption by entering a password while encoding.
Text Size Limit: Embeddable text is limited by the image's resolution. Larger images allow more hidden data.
100% Client-Side: This tool runs in your browser. No uploads, no data tracking, full privacy.
Do Not Compress Encoded Images: Re-editing or compressing the image may damage hidden content.
