In order to get or extract images from PDF document, I would suggest you use SysTools Free PDF Toolbox utility because it can extract any type of images from PDF document.
This tool provides two options -
1- Extract text from PDF
2- Extract images from PDF
With “Extract text from PDF” feature the image number containing some text can be extracted & with “Extract images from PDF” option, all the images present in your PDF file can be extracted.
Apart from this, you are also allowed to save the resultant image in any of the formats. Moreover, this utility also provides the option to select the page on which operation has to be performed. Once, you have completed the process of data extraction you can save the content in an Excel file.
