You need to paste or add the text message by yourself that you want to hide. Later, you can reveal hidden text from the output image using the same tool. To hide text in an image using this tool, open its homepage from github.io. There you will have two tabs or sections (Encode and Decode) which cover everything. Let’s check how to use these sections.

So, if you want to hide a large text, you should use a large size image. After adding the message, press the Encode button. This will generate the binary representation of your text message as well as the output image that will store that text message secretly. Now, right-click on the output image and use Save as to store the image on your Windows 11/10 computer.

Overall, the tool works well but it shows boxes or garbage content after the decoded message. But that can be ignored. Also read: Best File & Folder Encryption software for Windows
