Since you asked for the web-site in the other (true type) thread, I suppose I can post these here, too.http://www.extractpdf.com/
This is the one that also extracts true-type fonts, it extracts some
of the original image files from the forms switches at original resolution. I only gets the images with the grid on top, though.
On the other hand it is more successful at extracting various non-forms images from the front-page of my document, both compared to PDF Tools and compared to the other web-site. These extra images are white halos/filled outlines that are layered below the other images.http://www.pdfaid.com/ExtractImages.aspx
Here is another one that extracts these image files successfully. The main difference is that it you choose an image format for saving while the other one seems to extract the original image format. It creates various duplicates of the forms based images, but it also manages to extract both the grid and non-grid version of one of the images.
It extracts the same (fewer) images from the non-forms front-page as PDF Tools, just without the transparencies that Tools can do now.
