Hide files inside an image [OldSchool-Quick-Tip]

There are many ways to hide your

secrets, using encryption, hidden

folders, hidden partitions etc.

Sometimes the best place to hide

something is in plain sight. Here’s

an old forgotten trick that might

prove to be the best hiding place

ever…

Inside your images

The beauty of this method is that it doesn’t need any passwords (unless you really want to), algorithms,

encryption or special software. You can hide anything you like.

What you need

1. WinZip or WinRar or equivalent

2. Files to hide

3. An image (JPEG, GIF or PNG)

The instructions

1. Compress your files into a ZIP or RAR-file (Do NOT include the image).

NOTE! The Filename MUST NOT include spaces

2. Place the image of your choice in the same folder as the Compressed File

3. Open Command Prompt and open the Folder (type: CD\FolderName)

4. Type the following: "copy /b ImageFileName + CompressedFilename" and press Enter.

This Command will merge the second file into the first one.

In case you can’t read the image that well: copy /b TheDog.jpg + Secret.zip

5. After the confirmation, close the Command Prompt. Comparing the file size before and after is the only thing

revealing that the image contain more than, well an image.

If you want to avoid suspicion, remember that image file sizes rarely exceed 3-4 MB.

Simple isn’t it? I know you are going to ask: No, there is no reason why this shouldn’t work on AVI-files or

MP3-files or any other media-file as well.

How to access the Hidden Content…

Accessing the hidden files is just as easy. Even though it isn’t totally necessary, I would recommend that you

temporarily change the file-extension to either ZIP or RAR. Then right-click it and choose “Open With”. If you

don’t see WinZip or WinRar in the list, you have to locate it by expanding the view or use the Browse button. If

you decide not to change the file-extension then remember to disable the check box: “Always use the selected

program to open this kind of file”.
