To convert HTML to an image with Python and Selenium, open the HTML in a browser controlled by WebDriver and save a screenshot. The example below captures the browser’s current window as a PNG; use a browser-specific full-page method when you need the whole document rather than the visible viewport.
Set up Selenium and a browser
Current Selenium Python documentation supports Python 3.10 and later and recommends installing or upgrading the package with pip install -U selenium. Selenium automates a browser; it still needs a compatible browser, but Selenium Manager handles browser-driver setup in most supported environments when you create a WebDriver. Check the official Selenium documentation for current support and environment requirements, since package and browser support can change.
For a local script, you do not need Selenium Server. Remote WebDriver use requires Selenium Grid. The official docs list Chrome, Edge, Firefox, Safari, WebKitGTK, and WPEWebKit among supported browsers; availability depends on your runtime and platform.
- Install Python 3.10 or later.
- Install Selenium:
python -m pip install -U selenium. - Install or make available a supported browser. In most supported environments, Selenium Manager configures the driver when WebDriver starts.
Capture a local HTML file as a PNG
Save your markup as page.html, then run this script from a Python environment where Selenium and Chrome are available:

from pathlib import Path
from selenium import webdriver
html_path = Path("page.html").resolve()
output_path = Path("output.png").resolve()
driver = webdriver.Chrome()
try:
driver.get(html_path.as_uri())
saved = driver.save_screenshot(str(output_path))
if not saved:
raise OSError(f"Could not save screenshot: {output_path}")
finally:
driver.quit()Path.as_uri() creates a file URL for the resolved local path. save_screenshot() writes the current browser window as a PNG and returns a boolean; the check turns a failed save into a clear error. The finally block closes the browser even if navigation or capture raises an exception.
Capture a remote page instead
For a public URL, replace the local-file navigation line with driver.get("https://example.com"). The rest of the capture and cleanup code stays the same. The image shows the page as rendered in that browser session, including its CSS, fonts, images, and JavaScript state.
Choose the capture area and dimensions
Visible browser window
save_screenshot(path) captures the current window, not automatically the entire document. Set an explicit viewport size when the output must have predictable dimensions:

driver.set_window_size(1280, 900)
driver.get(html_path.as_uri())
driver.save_screenshot(str(output_path))Set the size before capture; setting it before navigation can also help pages lay themselves out at the intended width. Window dimensions alone do not control every visual variable: device scale, browser zoom, scrollbars, available fonts, and image loading can affect the rendered result. Verify those conditions in the target runtime if exact visual consistency matters.
One element
When the desired output is a component rather than the viewport, locate the element and use Selenium’s element screenshot method:
from selenium.webdriver.common.by import By
element = driver.find_element(By.CSS_SELECTOR, ".card")
element.screenshot("card.png")Replace .card with a selector in your page. Element capture is useful for a component image; confirm that the element is visible and that its content has finished rendering before taking the screenshot. See the Selenium WebDriver interactions documentation for element interaction and capture details.

Entire document
Full-document capture is not interchangeable with a viewport screenshot and is not exposed identically across browser drivers. Selenium’s Firefox Python API documents driver.get_full_page_screenshot_as_file(path) and driver.save_full_page_screenshot(path). These are Firefox-specific APIs in the documented bindings; do not assume they work unchanged with Chrome or every WebDriver implementation. Check the API for your chosen browser and test the result against the browser version you deploy.
For the ordinary viewport capture APIs, Selenium also documents get_screenshot_as_file(filename), which writes a PNG to a file, get_screenshot_as_png() for PNG bytes, and base64 screenshot methods for embedding. Consult the current Python WebDriver API for exact signatures.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Wait for the page to be ready
A screenshot records the browser state at capture time. If JavaScript, fonts, images, or other assets are still loading, the saved image may be incomplete. Prefer waiting for a meaningful page condition, such as the presence of a result element or an application-ready indicator, rather than relying only on a fixed sleep. A fixed delay can be too short on a slow run and unnecessarily long on a fast one.

- For dynamic content, identify a selector or application signal that means the relevant content is ready.
- For images, check that the images needed in the output have loaded before capture.
- For visual consistency, run with the same browser, viewport, fonts, zoom, and device-scale conditions as the intended output.
Troubleshoot common failures
| Symptom | Likely cause | What to check or do |
|---|---|---|
| WebDriver fails to start | The browser is missing, incompatible, or unavailable to Selenium Manager in the runtime. | Confirm a supported browser is installed and usable. Review Selenium’s current setup guidance; use manual browser-driver setup if Selenium Manager does not suit the environment. |
| The screenshot is blank or missing content | The page may not have loaded its dynamic content, fonts, or images before capture. | Wait for a meaningful ready condition and verify the page state in the same browser session before saving. |
| The output has the wrong size or crop | The script captured the viewport rather than the full document, or the window dimensions differ from the intended viewport. | Set an explicit window size. If you need the full document, use a full-page method documented for your browser driver. |
save_screenshot() reports failure |
The file could not be saved to the requested path. | Use an absolute output path and confirm the destination directory is writable; check the boolean return value. |
| Browser processes remain after an error | The driver was not closed when an exception occurred. | Put browser work in a try block and call driver.quit() in finally. |
Consider Playwright if the project is not tied to Selenium
Playwright is another documented Python browser-automation option. Its library guide covers Chromium, Firefox, and WebKit, and its screenshot guide shows saving an image with page.screenshot(path="screenshot.png"); browsers run headless by default. The documentation establishes that it can capture screenshots, not that it is faster or more faithful than Selenium. Choose according to your existing dependencies, target browser behavior, and required capture area. See the Playwright library guide and screenshot guide.
Or skip the browser setup
If you want an image from a URL without managing a local Selenium browser session, ScreenshotNeo provides a screenshot API and MCP server. One GET request returns an image or PDF. See the ScreenshotNeo website and API documentation.
import requests
r = requests.get(
"https://api.screenshotneo.com/v1/shot",
params={"access_key": "YOUR_API_KEY", "url": "https://stripe.com"},
timeout=90,
)
open("shot.webp", "wb").write(r.content)- Cookie banners are accepted and removed before capture, along with known newsletter popups and chat widgets; each of those steps can be turned off.
- Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits are not billed; response headers report the page verdict and billing status.
- An MCP server exposes screenshot, page-info, and PDF capture tools to AI agents and MCP clients.
- The Free plan includes 1,000 screenshots per month with no card. Paid plans start at $5 for 3,000 screenshots.

Frequently Asked Questions
Can Selenium save the screenshot as JPEG or WebP?
The Selenium screenshot methods documented here save PNG output. Use an image-processing step after capture if you need another format.
Does capturing a local HTML file require a web server?
No. The example opens the resolved file directly with a file URL. A server is only needed if your page or its assets specifically depend on being served over HTTP.
