This blog post explains how to easily upload PDF documents to the cloud, automatically convert them to images and back to PDFs, generate thumbnails dynamically, extract certain pages from multi-page documents and deliver through a fast CDN. All that done in the cloud without any software installation. Ruby on Rails, Python, Node.js and PHP sample code included.

does it supports bookmarks ? i.e. if the pdf document has internal links and bookmarks with the pdf those also ported to converted image?
