One free scan finds every outdated or missing driver and matches the right update for your exact hardware.Free scan · exact hardware matchFor a new Python screenshot workflow, start with Playwright: its Python documentation covers synchronous and asynchronous capture, viewport and full-page screenshots, image bytes, and locator-based element screenshots. Choose Selenium when your project already uses WebDriver. Pyppeteer documents useful screenshot controls, but its available API reference is version 0.0.25 and does not establish current maintenance or Chromium compatibility.
These are capability-based recommendations, not results of comparative testing. The cited sources do not establish which package is fastest, most reliable, or lightest on memory.
Which Python package should you choose?
| Package | What its documentation establishes | Best fit | Important limitation |
|---|---|---|---|
| Playwright for Python | Sync and async APIs; viewport and full-page screenshots; screenshot bytes; locator-based element capture. Official screenshot guide. | New workflows that need multiple screenshot scopes or a Python-facing browser automation API. | The documentation describes capabilities, not comparative speed or reliability. |
| Selenium WebDriver | Python examples save a screenshot of the current browsing context and an individual element. Chrome options include --headless=new. Screenshot examples; Chrome options. |
Projects already built around Selenium and WebDriver. | The cited screenshot example does not establish full-page capture support. |
| Pyppeteer | Its reference documents PNG/JPEG output, full-page capture, clipping, quality, and encoding options. Its project documentation describes it as an unofficial Python port for headless Chrome/Chromium. API reference; Project documentation. | Existing code that already depends on its API, after checking compatibility. | The cited reference is version 0.0.25 and old; current maintenance status is not established by these sources. |
Choose by the image you need and the automation stack you already maintain. A viewport screenshot is not the same as a full-page screenshot, and documentation that exposes an option is not evidence of how a package performs in a particular environment.
Capture a screenshot with Playwright
Install the Python package and its browser binaries using the current installation instructions for your environment. The screenshot API itself is the same whether the browser is launched headlessly or otherwise; the examples below use Chromium.

Simple viewport screenshot
from pathlib import Path
from playwright.sync_api import sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch()
page = browser.new_page()
page.goto("https://example.com", wait_until="load")
page.screenshot(path="screenshot.png")
browser.close()page.screenshot() captures the visible page viewport by default. Replace https://example.com with the target URL. The example waits for the load event; pages that render important content later may need an explicit wait for a selector or another condition meaningful to that site.
Full-page screenshot
page.screenshot(path="full-page.png", full_page=True)Use full_page=True when the output should extend beyond the viewport to the full page height. This is a different capture scope from the default viewport image. Very tall pages can produce large images; consider whether the consumer needs the entire page or only a particular section.
Async usage
import asyncio
from playwright.async_api import async_playwright
async def main():
async with async_playwright() as p:
browser = await p.chromium.launch()
page = await browser.new_page()
await page.goto("https://example.com", wait_until="load")
await page.screenshot(path="screenshot.png")
await browser.close()
asyncio.run(main())Use the async API when the surrounding application already uses asyncio; avoid mixing synchronous Playwright calls into an event loop.

Capture one element or keep the image in memory
# Save a locator's rendered element to a file
page.locator("main article").screenshot(path="article.png")
# Get screenshot bytes instead of writing a file
image_bytes = page.screenshot(type="png")Replace main article with a selector that identifies the element you need. Locator screenshots are useful for a card, chart, or component rather than a whole viewport. The byte-returning form can feed an image-processing or upload step without first creating a file.

Capture with Selenium when WebDriver is already your stack
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("--headless=new")
driver = webdriver.Chrome(options=options)
try:
driver.get("https://example.com")
driver.save_screenshot("screenshot.png")
finally:
driver.quit()The cited Selenium example uses driver.save_screenshot("screenshot.png") to save the current browsing-context screenshot. It should not be treated as evidence that this method captures the full document height. Selenium also documents taking an element screenshot:
element = driver.find_element("css selector", "main article")
element.screenshot("article.png")Use a selector that matches a rendered element on the page. Chrome’s Selenium-specific documentation lists --headless=new among commonly used arguments; browser options can change, so check the current Chrome and Selenium documentation for your installed versions.

Where Pyppeteer fits
Pyppeteer’s API reference documents screenshot controls including fullPage, clip, image type, quality, and encoding. Those controls may suit existing code that already uses its API. However, the available reference is for version 0.0.25 and is old. It does not establish present-day maintenance or compatibility with current Chromium releases. For a new project, verify the package and browser versions you intend to use before committing to it.
Wait for the right page state
A screenshot captures what the browser has rendered at capture time; successful navigation alone does not guarantee that client-rendered content, images, or an application-specific loading state is ready. Choose a wait condition based on the target page rather than adding an arbitrary delay by default.
Free tools Windows power users keep installed
One-click scans. No signup required.
- For ordinary document navigation, the examples wait for the page load event.
- For a client-rendered component, wait for the selector that indicates the component is present or ready.
- For lazy-loaded content, scroll or otherwise trigger loading before capturing if the required content is outside the initial viewport.
- If the page is authenticated or region-dependent, provide the needed browser state and verify the resulting page before saving the image.
The cited package documentation establishes screenshot APIs, not a universal readiness recipe. A site’s own rendering behavior determines the right condition.

Common problems and fixes
- The image is only the visible viewport. That is the default scope in the Playwright example. Set
full_page=Truefor a full-page Playwright capture; Selenium’s cited current-context example should not be assumed to provide that behavior. - The screenshot is blank or missing dynamic content. The capture may have happened before the application rendered. Wait for a meaningful selector or page state, then inspect the output.
- An element screenshot fails or captures the wrong area. Confirm that the selector identifies the intended, rendered element and that it is available before the call.
- Headless Chrome does not start. Check that the browser installation matches the automation package and that the runtime environment permits the browser to launch. For Selenium, verify Chrome options and the installed Chrome/WebDriver setup.
- Pyppeteer works in old code but fails with a newer browser. The cited reference does not establish current Chromium compatibility. Check the versions and compatibility of the package and browser before relying on it.
Performance, reliability, and cost: what the evidence supports
The cited sources provide no controlled comparison of these packages for speed, reliability, memory use, or cost. Do not select one on those grounds from the documented feature lists alone. In practice, screenshot time and output size can depend on the page, browser, wait condition, image dimensions, and capture scope; measure your own workload if those constraints determine the choice.
Or skip the browser setup
ScreenshotNeo is a website screenshot API and MCP server. One GET request can return an image or PDF, so you do not have to install or manage a browser for each capture. See the ScreenshotNeo API documentation.
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://example.com -o shot.webpScreenshotNeo accepts cookie or consent banners as a visitor and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; each of those steps can be turned off. Bot checks, blank pages, timeouts, failed loads, and cache hits are not billed, and the response identifies the page verdict and billing status in headers. Its MCP server provides take_screenshot, get_page_info, and capture_pdf tools for AI agents. The free plan includes 1,000 screenshots per month with no card; paid plans start at $5 for 3,000 shots. Sign up for 1,000 free screenshots a month, with no card required.
