How to Hide Files Inside Images using CMD Prompt
Step1:– Create a New Folder on the desktop, Rename it (lets say RIGHTyaLEFT) and add your files inside it.
Step2:– Compress the Folder into ZIP using any Compressor(I am using Peazip Compressor). I have compressed it to RIGHTyaLEFT.zip
Step3:– Now select the Image file in which you want to hide the data. Copy that image to the desktop.
Step4:– Open Command Prompt (Windows Key +R). Type cd “desktop” with the quatiation marks and press enter.
In the next line type copy /b picturename.jpg + fildername.zip outputfilename.jpg .
If you are using png or rar format then change it to the respective formats.
In my case- Its /b ilikan.jpg + RIGHTyaLEFT.zip newimage.jpg .
Thats it. Now you can use that image and send it to other friends to decode it.
How to Decrypt that image to get the file
Just Open Command Prompt and type CD “desktop” . Press enter and type ren output.jpg outputfil.rar . After that you can get your file extracted from the Picture.
This is the best method of Hide Files inside an Image without using any software. You can send this image to any of your friend through email easily.
