Hide encrypted text inside any PNG using LSB steganography. Decode later.
Uses LSB (least-significant-bit) steganography. Output is always PNG to avoid lossy compression destroying hidden data. Optional AES-256-GCM with PBKDF2 key derivation. All processing is local — your message and image never leave your browser.
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.
Image Steganography enables users to securely hide and extract secret text messages within PNG images directly in the browser using LSB steganography. With optional AES-256 password protection and 100% client-side processing, sensitive data never leaves the local device, ensuring complete privacy without requiring software installation or account registration.
Good to know: This tool is limited to PNG images and text payloads; workflows requiring non-PNG formats or large non-text file attachments will need an alternative approach.
Securely hide secret text messages inside PNG images using LSB steganography and optional AES-256 encryption.
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.
Enter your secret text message
Type or paste the private message you wish to hide into the provided text area. Ensure the message size fits within the capacity of your chosen image.
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.
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.
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.
