The Netherizer is a python based image steganography tool used for concealing files within RGB color data. Netherizer utilizes Pillow for image processing and tKinter for the GUI.
Variable Bit Depth: Control how much color data is overwritten starting with LSB (Least Significant Bit). Higher values allow for larger files but cause more changes to the image.
Transparency Write: Only write data to transparent pixels causing no visual change in the image.
Auto Bit Depth: Automatically choose the bit depth that will make the least possible change in the image.
