By the way, is there an opposite service that converts PDF's into plain HTML for reading? I know about https://www.arxiv-vanity.com/papers/ but it only works on arXiv PDFs.
There's another Apify act that extracts text from a PDF using the pdf-text-extract NPM package - see https://www.apify.com/juansgaitan/pdf-scraping If there's any library or tool that can convert PDF to HTML, it will only take a few minutes to setup such an API on Apify.
