Output Preview i

Output Preview

Description: A real-time viewport that renders the processed frames after color, contrast, and LSB filters are applied.
How-to: Use the playback controls to navigate. Observe the canvas for hidden text or patterns revealed by the sliders below.

Color & Contrast i

Color & Contrast

Description: Adjusts the visual properties of the media to expose data hidden in specific color channels or low-visibility areas.
How-to: Isolate color channels (Red/Green/Blue) or push Contrast/Brightness to the extremes to reveal faint steganographic "ghosts."

LSB Extraction i

LSB Extraction

Description: Scans the "Least Significant Bits" of pixels to find embedded binary data like text or file signatures.
How-to: Select the target bits (Bit 0 is most common) and click "Start Analysis" to parse the media for hidden payloads.

Target color channel

How extracted bits fill each byte

Bit 0 is standard LSB

Frame Timing

Adjust the time between frames. Range: 0.5–20.0 seconds. Default is 1.00 second.

Warning: significantly increases analysis time.

Visual Payload

            
Description: Shows channel-specific bit planes and local pixel differences from raw decoded
              pixels.

            
How-to: Compare the same bit across channels and regions. Structure can guide further extraction,
              but may also come from image content or compression.

Statistical Analysis

            
Description: Measures pair balancing and spatial behavior in each color channel's least
              significant bit.

            
How-to: Compare channels and confirm unusual results in the visual inspector. Compatibility with
              LSB replacement is an indicator, not proof of hidden data.

Description: Consolidates data found during LSB analysis or frame-by-frame text recognition (OCR).
            

            
How-to: Check this section after running an analysis to see decoded strings, URLs, or potential
              passkeys.
