Hi HN, Arek here. We’re super excited to officially launch PSPDFKit API [1]. PSPDFKit API is a collection of HTTP APIs that enable you to convert, generate, and edit documents without running any service on your infrastructure.

Hello HN! It kept surprising me how much of a hassle it is to generate a PDF with decent HTML5 rendering from my SaaS apps. I tried several free libs and APIs but ended up with botched rendering a lot of times. So I set out to simplify this chore by creating an AWS hosted HTML to PDF conversion API that's based on Chrome.
