Troonie is a portable open-source tool for viewing, editing and converting image files on Windows or Linux computers. It also comes with steganography tools using which you can hide files or text messages inside image files and later extract them from these images.
Troonie is portable and does not require installation. When you launch Troonie, you are presented with a small window with four options – Converter, Viewer, Editor and Steganography. Depending on which tool you choose, Troonie uses a different user interface. This small window interface disappearance as soon as you select one of the tools.
For the converter module, you have to select and add the source image files. Using this tool you can both resize and convert the image file format to JPEG, PNG or BMP files. For all of these target file formats there are different options available. After choosing an output file directory, you can click on the “Convert” button to process the files.
Troonie has an image viewer that can be used to view your image files. In the image viewer, it displays all the EXIF metadata tags if they are available. This is a very useful image viewer for photographers who want to look at the metadata information as they browse through their pictures collection.
In the editor part of Troonie, you can change the image size to pre-specified sizes. These cookie cutter sizes can be used to turn your pictures into some of the standard sizes like A4 or postcard. You can also use the stitching tool for joining two or more images horizontally or vertically.
In addition, Troonie has a possibility of hiding secret information in your pictures using steganography. This tool uses some sort of encryption to hide the text or file data inside JPEG images. The hidden data can later be retrieved using Troonie once again.
