Converting HTML & CSS into a PDF is simple with Urlbox.

It's a little more involved than converting a URL to a PDF. You need to send Urlbox your HTML and CSS.

First you need to prepare your HTML and CSS. We've added width, height and retina options here so it renders nicely.

{
  "html": "<html><head></head><body><h1>Hello World</h1><p>This HTML has been turned into a PDF.</p></body></html>",
  "css": "body{text-align:center;padding: 10px}",
  "width": "500",
  "height": "200",
  "retina": true
}

All that needs to be URI encoded for Urlbox to process it as a GET request:

https://api.urlbox.io/v1/[API_KEY]/pdf?html=%3Chtml%3E%3Chead%3E%3C%2Fhead%3E%3Cbody%3E%3Ch1%3EHello%20World%3C%2Fh1%3E%3Cp%3EThis%20HTML%20has%20been%20turned%20into%20a%20PDF.%3C%2Fp%3E%3C%2Fbody%3E%3C%2Fhtml%3E&css=body%7Btext-align%3Acenter%3Bpadding%3A%2010px%7D&width=500&height=200&retina=true

Linking to a dynamic PDF

Yes you can literally create a link to that and your users will be able to view the PDF:

<a href="https://api.urlbox.io/v1/[API_KEY]/pdf?html=%3Chtml%3E%3Chead%3E%3C%2Fhead%3E%3Cbody%3E%3Ch1%3EHello%20World%3C%2Fh1%3E%3Cp%3EThis%20HTML%20has%20been%20turned%20into%20a%20PDF.%3C%2Fp%3E%3C%2Fbody%3E%3C%2Fhtml%3E&css=body%7Btext-align%3Acenter%3Bpadding%3A%2010px%7D&width=500&height=200&retina=true" />View PDF</a>

Which would result in this:

View PDF

Maybe you want users to download the PDF with a particular filename? Easy, just add one parameter:

<a href="https://api.urlbox.io/v1/[API_KEY]/pdf?html=%3Chtml%3E%3Chead%3E%3C%2Fhead%3E%3Cbody%3E%3Ch1%3EHello%20World%3C%2Fh1%3E%3Cp%3EThis%20HTML%20has%20been%20turned%20into%20a%20PDF.%3C%2Fp%3E%3C%2Fbody%3E%3C%2Fhtml%3E&css=body%7Btext-align%3Acenter%3Bpadding%3A%2010px%7D&width=500&height=200&retina=true&download=my-document.pdf" />Download PDF</a>

Which would result in this:
