HTML PDF API is a cloud service that allows you to convert HTML to PDF using standard web technologies (HTML, CSS and JavaScript).
You can convert HTML to PDF from a raw HTML, compressed file (zip, tar.gz, tgz, tar.bz2) containing all resources (html, images, stylesheets, javascripts and fonts) and from URL.
API is built on the REST concept so it is language agnostic. It can be easily integrated with any programming language that supports HTTP requests.
