PixelSafe

PixelSafe provides a command‑line utility that embeds arbitrary binary data inside PNG files by modifying the image’s ancillary chunks. The tool reads a source PNG, inserts the payload into a non‑visual chunk, and writes a new PNG that retains the original visual appearance while carrying the hidden data. Extraction reverses the process, retrieving the embedded payload without altering the image.

The software is aimed at developers and researchers who need a simple, programmatic way to perform steganographic storage or transmission of data using the PNG format. Because it operates on standard PNG structures, it can be integrated into scripts, build pipelines, or testing frameworks where discreet data embedding is required.

PixelSafe is released under an open‑source license and is marked as experimental, indicating that it is still under active development and may lack extensive documentation or stability guarantees. Its focus on PNG‑specific chunk manipulation distinguishes it from more general steganography tools.
