How to convert HTML to a base64 image with Selenium and Python

Install Selenium for Python

pip install selenium

selenium 4.11+ includes Selenium Manager, which downloads the right chromedriver automatically — no separate driver install needed.

Get the base64 encoded image of some HTML and print to screen

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument('--headless=new')

driver = webdriver.Chrome(options=options)

html = '<html><body><h1>Hello World</h1></body></html>'
driver.get('data:text/html;charset=utf-8,' + html)

print(driver.get_screenshot_as_base64())

driver.quit()

That was 14 lines of code — plus a browser to run in production

Keeping headless browsers fed, patched and scaled is a job in itself. We built Urlbox so the same screenshot is one API call: 

curl "https://api.urlbox.com/v1/YOUR_API_KEY/png?url=https://example.com"
