How to Hide a File in an Image File

On Windows

1. 
   Copy the the file(s) and the image to your desktop. Select the files you want to hide, press Ctrl+C, go to your desktop, and press Ctrl+V, then do the same with the image you want to use.
2. 
   Select the file(s) you want to hide. Click and drag your mouse cursor across the list of files you want to hide.

   1. If you're just hiding one file, click once the file to select it.
3. 
   Right-click a selected file. Doing so will prompt a drop-down menu.

   1. If your mouse doesn't have a right-click button, click the right side of the mouse, or use two fingers to click the mouse.
   2. If your computer uses a trackpad instead of a mouse, use two fingers to tap the trackpad or press the bottom-right side of the trackpad.
4. 
   Select Send to. It's near the middle of the drop-down menu. A pop-out menu will appear.
5. 
   Click Compressed (zipped) folder. This option is near the top of the pop-out menu. Doing this creates a new ZIP folder with your files inside.
6. 
   Enter a name for the ZIP folder. After the ZIP folder appears, type in whatever you want to name the ZIP folder and press ↵ Enter.

   1. It's best if you choose a one-word name for the ZIP folder.
7. 
   Right-click the image. A drop-down menu will appear.
8. 
   Click Properties. It's at the bottom of the drop-down menu.
9. 
   Check the image's extension. In the parentheses next to the "Type of file" heading, you'll see the type of file your image is (this will usually be either ".jpg" or ".png").
10. 
    Copy the image's location. Click and drag your mouse cursor across the address to the right of the "Location" heading, then press Ctrl+C. This will ensure that you enter the path to your files correctly.

    1. You can close the Properties window after doing this.
11. 
    Open Command Prompt. Open Start

    

    , type in command prompt, and click

    

    Command Prompt at the top of the Start menu.
12. 
    Change the directory to your desktop. Type in cd and press the spacebar, then press Ctrl+V to paste in the copied address and press ↵ Enter. This will change Command Prompt's focus to use the desktop.
13. 
    Type in the "Copy" command. The command to place the file(s) in your image is as follows: copy /b image.extension+folder.zip image.extension where "image.extension" is replaced by the image's name and its extension (e.g., "hello.jpg") and "folder.zip" is replaced by the ZIP folder's name and extension (e.g., "hi.zip").

    1. For example, if your ZIP folder is named "Secret" and your image is a JPG named "Hide", you would type in copy /b Hide.jpg+Secret.zip Hide.jpg here.
14. 
    Press ↵ Enter. Doing so runs the command and places the ZIP folder inside of the image.
15. 
    View your hidden files. Once your image contains the ZIP folder, you can double-click the image file to open the image as-is; however, if you want to view the image's hidden files, do the following:

    1. Install WinRAR if you don't have it.
    2. Open File Explorer
       
       .
    3. Click the View tab.
    4. Check the "File extensions" box in the "Show/hide" section.
    5. Go to the image file you used, right-click it, and click Rename.
    6. Replace the image file's extension with "rar" (e.g., "Hide.jpg" would become "Hide.rar").
    7. Press ↵ Enter, then click Yes when prompted.
    8. Double-click the image file to open it in WinRAR.
