Embed or extract hidden text using Least Significant Bit (LSB) encoding in pixel data. Supports UTF-8 text with a clear, consistent protocol.
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.
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.
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.
Same core engine on iPhone, iPad, and Mac with a single, clean interface.
Built-in short guide to steganography, LSB and EOF concepts, and how to spot hidden content. Whether you are learning or checking if an image carries hidden data, StegInsight gives you the tools.
The developer does not collect any data from this app. All analysis and embedding happen on your device. Your images and hidden content never leave your iPhone, iPad, or Mac.
We do not collect any personally identifiable information or usage data from StegInsight.
All steganography and image analysis are performed locally. No cloud uploads or server transmission.
Hide sensitive text inside ordinary images. Share images that carry a second layer of information visible only to those who know how to look.
Check whether images contain trailing data or LSB-encoded content. Inspect bit planes and hex preview to understand what is hidden.
Use the built-in guide to understand LSB encoding, EOF trailing data, and how to spot or create hidden content in images.
Support for common steganography techniques and file formats (JPEG, PNG) useful in capture-the-flag or forensic workflows.
