StegInsight

Steganography & Image Analysis

$2.99

Uncover the hidden. Detect trailing data, visualize LSB bit planes, and embed or extract text in images. The steganography tool for iOS & macOS. Discover what lies beneath the surface of your digital images. StegInsight is a multi-platform tool for privacy enthusiasts and security-minded users to analyze and use steganography: hide or reveal text inside images. Key Features • LSB Steganography — Embed or extract hidden text using Least Significant Bit (LSB) encoding in pixel data. Supports UTF-8 text with a clear, consistent protocol. • LSB Bit-Plane Visualization — View the LSB layer of the red, green, and blue channels as grayscale images. Random noise suggests a normal image; regular patterns may indicate hidden LSB data. • Trailing Data Detection — Scan for data appended after the end of image files (EOF). See byte count, hex preview, and decoded text when the trailing data is valid UTF-8. Supports JPEG and PNG. • Dual Embedding Modes — Hide text in pixel LSBs or append it after the file’s logical end (EOF) for JPEG/PNG. Export results as PNG or save back to the photo library (iOS) or file. • Cross-Platform — Same core engine on iPhone, iPad, and Mac with a single, clean interface. • Learn — Built-in short guide to steganography, LSB and EOF concepts, and how to spot hidden content. Whether you’re learning how steganography works or checking whether an image carries hidden data, StegInsight gives you the tools to look under the surface.
