30 Useful Steganography Tools To Hide Secret Information

Steganography is the science of hiding secret data inside larger and harmless looking files, like picture, sound, text, etc. For example, the hidden message may be invisible ink between the visible lines of private letters.

What are the advantages of Steganography over Cryptography?

Cryptography is the practice of securing the content of a message alone. On the other hand, steganography is concerned with concealing the fact that a secret message is being sent, as well as concealing the content of the message. Therefore, the intended secret message does not attract attention to itself as an object of scrutiny.

We’ve compiled a pretty useful list of multi functional steganography tools that will help you easily transmit your messages in a safe and secure way.

30. JHide


JHide is a small software application designed to hide sensitive files within custom images. The pictures that contains the private files can be opened with the same dedicated viewers, sent via emails, or printed. In order to decrypt the file one need to specify the host image and the correct password. Moreover, the software comes with an intuitive layout that gathers all configuration settings into a single window.
