If you are looking for a tool to embed secret messages into images without leaving a trace, this app can help you. It uses an algorithm that hides data within images without leaving any trace. You can use it with your network turned off, if you feel paranoid.

It can hide a short second message which will need a separate password that can only be retrieved if both Passwords are correct. You can also hide data in a small image box that is visible only based on your corresponding Password.

For more security, you can also hide multiple images using the same Password. The password can be typed, pasted, or loaded by using the toolbar buttons.

The only images that can be hidden are those that are smaller than the size of the hidden data.
