How to hide data inside images?

1. Create a folder. Name it anything you wish, say hide.
   
   
   
2. Now put anything and everything you want to hide in this folder. Text files, other images, executables - anything. Also, put the image behind which you want to hide the files in the same directory, say “image.jpg”.
   
   
3. Now we need to archive this folder. You can use your choice of compression tools for this (I recommend the free and open source 7-zip). So now we have hide.zip containing all of the data we want to hide behind an image.
   
   
4. You should have your image, say image.jpg (inside of which we’ll hide our data) in the same directory as hide.zip (next to it).
   
   
5. Now simply open up the command prompt and move to the folder where image.jpg and hide.zip.
   For example:
   

   Hold Shift Key same time mouse right click show the command windows here.
   
   
   

6. Now we type in the following command:
   

   copy /b image.jpg + hide.zip output.jpg
   

After running this command, you should see an output.jpg in the folder and if you look closely, you’ll notice that it’s size has increased by approximately the size of the archive. Our data is now hidden behind the image.

The newly created output.jpg behaves like a normal image file, but you can also view the hidden data by opening the file with your compression tool, say 7-zip (Right click -> Open with -> 7-zip).
