A better description would be encrypter. Any file placed in the input folder will be converted to an image. Multiple files are supported as well. There is still a lot of problems like the f2i speed as well as memory usage.
For example, converted files increase up to 250% in size!
The image to file (i2f) converter is significantly faster and works pretty well at this point.
You will need Pillow, bitstring and numpy.
Use pip install bitstring, numpy, Pillow to install.
