Image compressed file

Image Compressed File is a useful image compression tool that can help users compress images quickly!

Why do we need to compress image files?
1. Because on some sites that only allow the upload of jpg or other formats, other files that are not allowed to be uploaded can be compressed and bound to the jpg file. In this way, the photo album of the website becomes a toolbox for us to store files.
2. It is also a good method to encrypt some special files in this way. In this way, when others see this file accidentally, it is also a picture. Who would have thought that there are other contents hidden in it!

Function introduction

Picture-type compressed files use the COPY command in the CMD command to combine pictures and compressed files into picture files. You can view the contents of the compressed file after changing the suffix name. Production files are saved in the directory where the software is located by default.
 

How to turn compressed files into images?
Put the .rar file and the .JPG file in the same directory, create a new .TXT file, and then enter
COPY filename.JPG /B + filename.RAR = filename.JPG
The first is the file name of the image, the second is the RAR file name, and the last is the output file name. Finally, change the .TXT suffix to .BAT and run it.
