Indexing Images in PDFs: Google

Google Indexes Images From PDF Files

Google Operating System | August 9, 2015

I'm not sure if this is a new feature, but I noticed that Google indexes images from PDF files. Google adds "[PDF]" next to the title of the page and offers a single option: "view PDF", since it can't link to an image from a PDF file.
Back in 2008, Google started to use OCR to index the full text of scanned PDF files. Now Google extracts images from PDF files and makes them searchable.

Above search is "https://www.google.com/search?q=google+pdf+site:static.googleusercontent.com&tbm=isch". Usually, when users search for specific images they see the option of “View Image” or “View Webpage” in the image search options, however, a “View PDF” shows up on an embedded image from a PDF. This feature will simplify the process of searching for manuals and specific reports, as viewers will be able to view a report without downloading it.
