A simple-to-handle piece of software that helps you encrypt private text messages into PNG files and password-protect them with an encryption key

editor's review




SteganoImage is a small Windows application designed specifically for helping you embed hidden text messages into PNG files. The output pictures that include the sensitive data can be opened normally with the aid of your default viewer, so they don’t raise any suspicions.

The advantages of being portable

Since this is a portable program, it is important to mention that it doesn’t leave any traces in the Windows Registry.

You can copy it on any USB flash drive or other devices, and take it with you whenever you need to conceal private data in pictures on the breeze, without having to go through installation steps.

Multi-tabbed layout and supported file format

You are welcomed by a clean feature lineup that allows you to conceal private text in the desired photo with just a few clicks and extract data from images. Additionally, the tool offers support for a previewing panel where you can analyze the image in detail.

It works with a single file format (PNG) and lets you upload items in the working environment using the built-in browse button or drag-and-drop support.

Concealing capabilities

SteganoImage gives you the possibility to pick the desired image, type in the text message directly into the main panel, paste it from the clipboard, or upload it from a file, enter a user-defined encryption key, as well as pick the desired method (e.g. Optimal, Very Capable).

The output picture can be exported to PNG file format, provided that you have specified the filename and saving directory. When it comes to extracting the sensitive information from images, you need to select the photo and enter the correct encryption key.


During our testing we have noticed that SteganoImage carries out a task pretty quickly and without errors. It doesn’t eat up a lot of CPU and memory, so the overall performance of the computer is not affected.

Bottom line

All in all, SteganoImage proves to be a simple software application that helps you encrypt private text messages into PNG files and password-protect them with an encryption key.
