How to convert an HTML String to PDF in Python

Today I will be demonstrating how to fully render an HTML string, then convert the website into a PDF document. This will have support for CSS, Javascript, and HTML5, among other things. Don’t worry, though, this isn’t going to be a very time-consuming process. We are using an API shortcut.

We will need the API client installed before we can do anything else:

pip install cloudmersive-convert-api-client

Now create an API instance using a key, and call convert_web_html_to_pdf from this instance:

from __future__ import print_function
import time
import cloudmersive_convert_api_client
from cloudmersive_convert_api_client.rest import ApiException
from pprint import pprint
# Configure API key authorization: Apikey
configuration = cloudmersive_convert_api_client.Configuration()
configuration.api_key['Apikey'] = 'YOUR_API_KEY'
# Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
# configuration.api_key_prefix['Apikey'] = 'Bearer'
# create an instance of the API class
api_instance = cloudmersive_convert_api_client.ConvertWebApi(cloudmersive_convert_api_client.ApiClient(configuration))
input = cloudmersive_convert_api_client.HtmlToPdfRequest() # HtmlToPdfRequest | HTML to PDF request parameters
try:
# Convert HTML string to PDF
api_response = api_instance.convert_web_html_to_pdf(input)
pprint(api_response)
except ApiException as e:
print("Exception when calling ConvertWebApi->convert_web_html_to_pdf: %s\n" % e)

Now input our string and extra wait time allowed, like this:

{
  "Html": "string",
  "ExtraLoadingWait": 0
}

And your HTML will be rendered and converted to PDF, no problem.
