In a simple way i shall teach you a way for hiding a text inside a picture file.
Hide a Text File With an image file:
For example think we have to hide a text file a.txt with the image file b.jpg and combine them in a new file as c.jpg .Where c.jpg is our output file which contains the text hidden in the image file.
Open Run command window by pressing win + r .
Open command prompt by typing cmd and press ok
Enter the directory where you have your files.
Then type the command :
copy /b a.txt + b.jpg c.jpg
Now our file is successfully hidden in a new file.
How can I view my files ?
When you normally open the output file c.jpg you will see the image file but how to view your hidden text file Right click the image file .
select open with notepad.
Successfully opened ! In the last of the notepad you’ll find the content of the text file.
Hide A Message Into Image:
Open Run command window by pressing win + r .
Open command prompt by typing cmd and press ok
Enter the directory where you have your files.
Then type the command :
echo "Your Message">>"image.jpg"
