HTML to PNG with Python and Selenium

Install Selenium for Python

pip install selenium

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

Convert HTML to PNG and save to file

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)

driver.save_screenshot('html.png')
driver.quit()

That was 13 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"
