How to Hide Data Behind Image?
Step 1: Create a folder of the name of your choice in C drive (You can create it in any drive, just creating a folder in ROOT directory is easier). Suppose I have created a folder name “hide” in C drive.
Step 2: Now put all of your secret files in this folder. Suppose I want to hide my ppt files so I will put it in my “hide” folder. The files can be of any type and you can also put multiple files.
Step 3: Now put the image behind which you want to hide all your files, in the same directory. Suppose I want to hide my data behind “nature.jpg”, I will put this image into C directory (Same directory as the folder).
Step 4: Next step is to compress the folder into which all your hidden files are placed. So, I have the folder named “hide”, right click on it, and click “Add to archive…”. Now the .rar file of the folder “hide” will be created (hide.rar) on the same drive (mine is C drive).
Step 5: Now open the terminal or command prompt. You can start it by searching for “cmd” or you can press “Windows key+R” type “cmd” and hit “Enter”.
Step 6: Change the directory to your current directory. You can do this by two ways:
1- cd C:\\ (or the name of your drive instead of “C”).
2- Press “Shift+Right click” from your drive and select -> “Open command window here”
Now, carefully type this command:
Copy /b image.jpg + hide.rar output.jpg
“image.jpg” is the image behind you want to hide all your secret data (mine is Nature.jpg).
“hide.rar” is the folder containing secret files (mine is Hide.rar).
“output.jpg” is the name of output file you want. This file will contain all your secret data but it will look like an image (mine is secret.jpg).
Execute the above command and you will see the image named “output.jpg” in the same directory. The size of this image will be, the size of original image+size of the hide.rar folder. If the command isn’t able to access the files, then try it in the different directory.
Now, the question is how to open the secret files? Well! It’s pretty simple. You can double click on the image and it will open like a normal image. But, if you want to see the hidden files then just “Right click” on image and “open with-Winrar” or any of your compression tool like Winzip.
This is it! Now you can enjoy sending secret files to your friends by hiding it behind images. Just make sure your friend knows how to open it. This trick works with almost any type of file (because all type of formats can be compressed). On the last note, you may want to keep your file size small. Because you cannot hide 13GB setup file of FIFA 15 behind a 10 kb picture without creating suspicion.
