Steganography is the practice of hiding information
within another non-secret file to conceal its existence entirely.
Unlike encryption (which hides content), steganography hides
the existence of content itself.
In this tool, we embed your message into the pixel data of an image using LSB
manipulation.
The resulting file looks identical to the original image but secretly carries your
hidden data.
We do not store, log any key you enter.
This tool is intended for personal and educational use.
We suggest not to use online tools to protect real production secrets.
Image Steganography – Tool Overview
Our free Image Steganography Tool lets you
securely hide any secret text or data inside an
image without changing its visible appearance. Using advanced LSB (Least
Significant Bit)
steganography combined with AES
encryption, your message remains completely invisible
and extremely hard to extract without the correct secret key.
Everything runs directly inside your browser — no uploads, no tracking, and no data
stored on our servers.
This tool is built for users who value privacy, anonymity, and strong data
protection.
✨ Key Features of Our Steganography Tool
- Client-Side Processing Only – No data is ever uploaded or
stored
- AES Encryption for securing your message before embedding
- Real-time Image Preview before hiding your text
- Supports PNG and JPG image formats
- Automatic Stego Image Download with original filename preserved
- Easy Text Extraction using the extract tab
- Fast, lightweight and privacy-focused
🛠 How Does It Work?
- You upload an image (PNG/JPG)
- Enter your secret message and encryption key
- The message is encrypted using AES encryption
- The encrypted data is hidden inside the image pixels
- You download the new image (stego file)
- Only someone with the correct key can extract and decrypt the data
🧩 Use Cases
- Protect sensitive messages
- Share secret codes or credentials
- Send notes that avoid detection by automated scanners
- Digital watermarking & copyright marking
- Research, academic, and cybersecurity learning
🌐 Why This Tool Is 100% Safe
Unlike online steganography websites that upload your data to their server,
our tool performs 100% client-side operations.
- No server storage
- No logging
- No tracking
- No message retention
- Everything happens in your browser’s memory
Once you close the page, everything is wiped automatically.
Frequently Asked Questions
No. All encryption and embedding operations happen on your browser.
We do not store your text, files, or keys anywhere.
The tool supports PNG and JPG/JPEG
images.
These formats are widely used and ideal for LSB steganography.
Visually, no. The image appears unchanged.
Even if someone suspects steganography, they still need your secret
key to decrypt the message.
Yes. The message is encrypted using AES before embedding.
Even if someone extracts raw bytes, they cannot decrypt without your
key.
The visual quality remains the same.
Only the least significant pixel bits are altered, which is
undetectable to the human eye.
