PDF files are created in two ways i.e. either through office files, images, etc. or by scanning the actual paper of the documents. Google now lets you recognize the text from PDF files. It means that Google can convert the scanned files into plain text. To convert the scanned PDF file into the text, you can simply create a file in your website where you can upload all the PDF images. Let Google bots access them and once they do, you can just type “site address filetype:pdf” and see the PDF documents as HTML.
