Steganography Tool
Detect and analyze hidden data in images. Encode secret messages or extract hidden content using LSB steganography techniques.
Detect Steganography
Upload an image to analyze for hidden data using multiple detection techniques including LSB analysis, chi-square test, and entropy analysis.

About Detection
- LSB Analysis: Examines the least significant bits of pixels for hidden data patterns
- Chi-Square Test: Statistical test that detects non-random distributions in pixel values
- Entropy Analysis: Measures randomness - embedded data often increases entropy
- Best Results: Use PNG or BMP images (JPEG compression destroys hidden data)
Extract Hidden Message
Extract text hidden in an image using LSB steganography. The message must have been encoded using standard LSB technique.

Must be PNG or BMP (lossless format)
Tips
- Only works with images that have data hidden using LSB steganography
- JPEG images lose hidden data due to lossy compression
- The image must not have been edited or re-saved after encoding
Hide Message in Image
Embed a secret message into an image using LSB steganography. The output image will look identical to the original.

Message Hidden Successfully
Security Notes
- Save as PNG: JPEG compression will destroy the hidden message
- Don't edit: Any modifications to the image may corrupt the message
- Capacity: Larger images can hide more data
- Detection: LSB steganography can be detected with proper tools
