You can also perform this action with Acrobat Reader and the image selection tool, only one by one and not in batches.
All you need to do is indicate which pages you want to obtain pictures from. If you don't, the program will extract images from the entire document, but this is not recommended.
The images are saved in BMP format in the same folder as the source file, or in a folder specified by the user.
Less than four steps are required to extract the images. If the document is password-protected, simply enter it in the wizard and you're all set.
