We are releasing our HTML to PDF REST API to public preview: https://html2pdf.appbeat.io/
We are using this tool internally for generation of various PDF documents. It uses Chrome engine for HTML rendering and creates really nice looking documents.
It supports synchronous and asynchronous operation where you can be notified about PDF conversion result via webhook.
