Mimage

Steganography is a practice that allows you to hide a file within another file, the latter usually being an image. To do so, you need a dedicated application, and one example is Mimage.

This particular application requires no installation, so you don't have to go through a setup process. Double-clicking on the executable file starts Mimage, revealing its simplistic one-window interface.

Working with Mimage is very easy, especially since some of the commands already have associated hotkeys (unfortunately, it's not possible to customize them).

You start by browsing for the source image to hide files in, in JPG or PNG format. As soon as you select it, a preview is displayed. Next, you have to choose the files to hide inside the image, no matter their type. You can conceal other images, videos, documents, or any other file.

The so-called "steg image" is the name of the output image, which will contain all the hidden data. If the file does not exist, the application creates it for you. There's only one thing to take into account: the steg image file type must match the format of the source picture.

Pressing the "Hide" button instructs Mimage to start the procedure and hide the files. You can add AES-256 password protection to the resulting image, but this is optional.

To extract the hidden content, Mimage requires you to select a location and provide the correct password, if any.

Mimage's might seem rudimentary, but it comprises easy to use options, which makes the application fit for any type of user, regardless of their experience. As a consequence, Mimage manages to provide users with a straightforward way to hide files inside images and share them without the risk of personal data being intercepted.
