Converting HTML & CSS into a PNG is simple with Urlbox.
It's a little more involved than converting a URL to a PNG. 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 PNG.</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]/png?html=%3Chtml%3E%3Chead%3E%3C%2Fhead%3E%3Cbody%3E%3Ch1%3EHello%20World%3C%2Fh1%3E%3Cp%3EThis%20HTML%20has%20been%20turned%20into%20a%20PNG.%3C%2Fp%3E%3C%2Fbody%3E%3C%2Fhtml%3E&css=body%7Btext-align%3Acenter%3Bpadding%3A%2010px%7D&width=500&height=200&retina=trueEmbeding a dynamiclly generated PNG
Then you can literally create an HTML image tag with that as the src and it will render:
<img
src="https://api.urlbox.io/v1/[API_KEY]/png?html=%3Chtml%3E%3Chead%3E%3C%2Fhead%3E%3Cbody%3E%3Ch1%3EHello%20World%3C%2Fh1%3E%3Cp%3EThis%20HTML%20has%20been%20turned%20into%20a%20PNG.%3C%2Fp%3E%3C%2Fbody%3E%3C%2Fhtml%3E&css=body%7Btext-align%3Acenter%3Bpadding%3A%2010px%7D&width=500&height=200&retina=true"
