Although there are many services and options to send messages or text in an encrypted way, adding them to an image makes it much more secure as it is hidden. SteganoImage is a freeware tool for Windows which allows you to encrypt messages or text into an image and it stays hidden and no user will be able to view it. You can even attach content on to the image like plain text files or other files depending on the image capabilities.
You can select the PNG image and the tool calculates the image container capacity. Based on the capacity you can add plain text or attach multiple files. Once attached, you can specify the encryption key and the method of encryption.
You can share the encrypted file to other users and they can decrypt it using the same app. Since the app is portable, there isn’t any hassle of installation, you can carry in USB pen drive.
