Media to Analyze

Drop image or audio file

Analyze for hidden data signatures

Analysis Results

Click ANALYZE to inspect media...

Color Channel Layers

Separate R/G/B/A channels can reveal hidden text or patterns

RED Channel

GREEN Channel

BLUE Channel

ALPHA Channel

Steganalysis Transforms

Advanced transforms to detect hidden data

Luminance (Y)

Inverted

Edge Detection

Noise Residual

XOR Checkerboard

LSB Randomness

YCbCr Color Space

JPEG uses YCbCr - hidden data may appear in Cb/Cr chrominance channels

Y (Luminance)

Cb (Blue Chroma)

Cr (Red Chroma)

Histogram Analysis

Uneven distributions or gaps can indicate steganography

■ Red ■ Green ■ Blue ■ Luminance

Pixel Zoom

Click on the image to zoom - inspect individual pixels

Chi-Square Analysis

Statistical detection - red areas have abnormal LSB distribution (likely steg)

■ Normal (χ² < 10) ■ Suspicious (10-50) ■ Likely Steg (χ² > 50)

DCT Block Analysis

Visualize DCT coefficients - anomalies reveal DCT-based steganography

File Structure Analysis

Check for data hidden after image end marker or in metadata

Load a file via the file input to analyze structure...

🔬 Universal Metadata Decoder

Comprehensive analysis of ALL metadata channels where data could be hidden

📷 EXIF Data (Exchangeable Image File Format)

Camera info, GPS, timestamps, MakerNotes - common hiding spots for data

Click "ANALYZE ALL METADATA" to extract EXIF data...

📁 Format-Specific Metadata

GIF extensions, WebP chunks, BMP headers, and other format-specific hiding spots

Load an image to analyze format-specific metadata...

🪆 NESTED STEGG 🪆

Multi-Layer Steganography

🔐 Nested Encode

Hide your payload inside N auto-generated nested layers, wrapped in your carrier image.

Embedding Mode

LSB: Higher capacity, fragile to compression

👻 Ghost Mode

ENABLE GHOST MODE

AES-256-GCM + Bit Scrambling + 50% Noise Decoys
⚠️ Requires password mode • Halves capacity

Stealth Options

Basic encryption

XOR cipher (fast, basic obfuscation)

Statistical balancing

±1 modifications to preserve histogram

Density

50%

Lower = more sparse, harder to detect

Decoded Data

🔤 Text Steganography Lab

Hide messages in plain text using invisible characters and visual tricks

Method

Embeds secret as invisible zero-width characters between visible letters. Completely invisible in most applications.

Swaps normal letters with Mathematical Bold variants (U+1D400). Visually bold but encodes 1-bits. Normal = 0.
