How to convert HTML to PDF

To convert HTML to PDF, send the HTML or the URL of a public web page to the 1001fx function html2pdf – from Make, n8n or the 1001fx app. It prints the page with Chromium like a browser, with CSS, web fonts and images, and returns the PDF file.

Tips

  • Put the CSS into the HTML itself. Images, style sheets and web fonts only load if their URLs are public.
  • Set margin to a CSS length such as 10mm or 0 to control the white border around the page.
  • Check your API key first with playground/hello, which does not charge credits.
