Use Playwright’s page.screenshot() after navigating to the target URL. Launch Chromium with headless: true (the documented default), wait for the page state your capture needs, and save the result with a path or keep the returned buffer. Add fullPage: true for the entire scrollable page, or capture a locator when you need one element.
Install Playwright and a browser
These commands create a small Node.js project and install Playwright with its browser binaries:
mkdir playwright-shots
cd playwright-shots
npm init -y
npm install playwright
npx playwright install chromiumThe examples below use Chromium. You can replace chromium with another Playwright browser when your project requires it. Run the script with node screenshot.js.
Take a basic screenshot in headless mode
Create screenshot.js with this complete script:
const { chromium } = require('playwright');
(async () => {
const browser = await chromium.launch({ headless: true });
const page = await browser.newPage();
await page.goto('https://example.com');
await page.screenshot({ path: 'screenshot.png' });
await browser.close();
})();page.goto() loads the page, and page.screenshot() writes screenshot.png in the current directory. Headless mode runs without opening a visible browser window. Playwright’s BrowserType API documents headless mode as the default, but stating it explicitly makes scripts and deployment settings unambiguous.

- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Wait for the page state you actually need
A navigation promise resolving does not guarantee that a late-rendered chart, font, or image is visible. Add a locator wait for the content that defines a usable capture:
await page.goto('https://example.com/dashboard', { waitUntil: 'domcontentloaded' });
await page.locator('[data-testid="dashboard-ready"]').waitFor();
await page.screenshot({ path: 'dashboard.png' });Use a selector that represents readiness rather than an arbitrary long delay. If the site has no reliable readiness marker, a short, deliberate delay can be used, but it is less deterministic than waiting for a specific element.
Choose what Playwright captures
Viewport screenshot
With no area option, Playwright captures the current viewport. Set the viewport before navigation when a particular layout matters:
const page = await browser.newPage({ viewport: { width: 1440, height: 900 } });
await page.goto('https://example.com');
await page.screenshot({ path: 'viewport.png' });This is usually the most reviewable artifact for a responsive breakpoint because its dimensions match what a user sees at that viewport.

Set fullPage: true to capture the page’s full scrollable height:
await page.screenshot({ path: 'full.png', fullPage: true });Full-page images preserve one long document, which is useful for archiving or visual review, but they can become very tall and harder to inspect. If a page changes layout while scrolling or contains fixed overlays, compare the output carefully with a viewport capture.
One element
Use a locator’s screenshot method for a component such as a header, card, or chart:
await page.locator('.header').screenshot({ path: 'header.png' });Playwright scrolls the locator into view first. It does not reveal pixels covered by another element, and a scrollable element captures only the content currently visible inside that element rather than all of its internal scroll range.

await page.screenshot({
path: 'region.png',
clip: { x: 100, y: 120, width: 800, height: 500 }
});Clipping is useful when the target is not a stable locator. Keep the rectangle inside the rendered page; a stale coordinate can produce the wrong region after a responsive layout change.
Control image format, scale, and appearance
Playwright infers the image type from a supplied filename extension. When no type can be inferred, PNG is the default. The supported screenshot types are PNG, JPEG, and WebP.
| Setting | Example | Use it when |
|---|---|---|
| PNG | path: 'shot.png' |
You need lossless output or transparency. |
| JPEG | path: 'shot.jpg', quality: 80 |
You want a smaller lossy image; JPEG does not support transparency. |
| WebP | path: 'shot.webp', quality: 80 |
You want a modern compressed format supported by your pipeline. |
| CSS scale | scale: 'css' |
You want one image pixel per CSS pixel and a compact artifact. |
| Device scale | scale: 'device' |
You need device-pixel detail, accepting a potentially larger file. |
When saving JPEG or WebP, set quality to control lossy compression. The exact visual result depends on the page and the chosen quality value.

Pick the symptom - the matching free tool is one click away.
Freeze motion for deterministic captures
Animations are allowed by default. Disable CSS animations, transitions, and Web Animations during capture when motion would make screenshots vary:
await page.screenshot({
path: 'stable.png',
animations: 'disabled'
});Playwright treats finite and infinite animations differently when disabling them, so verify that the resulting frame is the one your review or test expects. Disabling animation is a test aid, not a substitute for checking a real animation bug.
Transparent backgrounds
Use omitBackground: true when you need the page’s default background removed. This is intended for formats that support transparency; it does not apply to JPEG.
await page.screenshot({
path: 'logo.png',
omitBackground: true
});Mask dynamic regions
Mask locators that legitimately change, such as timestamps or rotating identifiers, so visual comparisons focus on stable layout:
await page.screenshot({
path: 'masked.png',
mask: [page.locator('[data-testid="clock"]')]
});Masking hides a known dynamic region; it should not hide a genuine layout regression. The screenshot API also supports injected screenshot styles when a temporary style rule is a better way to neutralize a component.
Save to a file or keep the image in memory
Passing path writes the image directly. Omitting path returns a buffer, which is useful for uploads, hashing, or sending the image to another service without creating a temporary file:

await require('fs').promises.writeFile('buffer-shot.png', image);If you provide both a path and processing logic, remember that the returned value is the captured bytes; your application can choose whether to persist, upload, or transform them.
Use screenshots in Playwright Test
Manual page.screenshot() calls are explicit workflow steps. Playwright Test can collect screenshots automatically as test artifacts with modes such as on, only-on-failure, and on-first-failure. It can also be configured for full-page screenshots. This test-runner configuration is separate from a manual screenshot call.

Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Automatic failure artifacts are convenient when you mainly need evidence of a failed test. A manual call is better when the screenshot is part of the test’s actual assertions, documentation, or a named output contract.
Make visual comparisons reliable
Rendering can vary with the host operating system, browser version, browser settings, hardware, power source, and headless mode. Generate and compare baselines in the same environment whenever possible. Keep the browser binary, viewport, device settings, and animation state consistent between baseline and comparison runs.
When a screenshot unexpectedly differs, check these variables in order:
- Confirm the browser and browser version used for both images.
- Compare viewport dimensions, device scale, and any emulated device settings.
- Check whether animations, transitions, caret blinking, or delayed content were active.
- Verify that fonts, images, and network data finished loading before capture.
- Mask only regions that are genuinely nondeterministic, and investigate every unmasked difference.
Playwright’s screenshot assertion waits for two consecutive screenshots to match before comparing against the expected image. That stability check helps with brief layout settling, but it cannot make two different environments identical.
Troubleshoot common failures
“Executable doesn’t exist” or browser launch failure
Cause: the Playwright package is installed but its browser binaries are missing, or the runtime user cannot access them.
Fix: run npx playwright install chromium in the same environment that runs the script. In a container or CI job, install browsers during the image build and verify filesystem permissions.
The screenshot is blank or captured before content appears
Cause: the page is still rendering client-side content, a required request failed, or the script captured immediately after navigation.

Full-page output is unexpectedly short
Cause: the document has not expanded yet, content is inside a separate scrollable container, or lazy content requires an interaction or scroll.
Fix: wait for the content that defines the final height. If the content lives in a nested scroll area, capture that locator or scroll it deliberately; fullPage refers to the page’s scrollable document, not every nested container.
An element screenshot misses part of a panel
Cause: the locator points to a scrollable element, or another element covers the missing pixels.
Fix: capture the visible state after scrolling the panel to the required position, remove the covering overlay only when that reflects the intended test state, or use a different locator for the content you need.
Recommended Free Tools
Images differ between local and CI
Cause: OS, browser, hardware, power mode, viewport, device scale, fonts, or animation state differ.
Fix: standardize the execution image and browser, set the viewport explicitly, disable or control animation, and regenerate baselines only after confirming the change is intentional.
The file is too large
Cause: a full-page capture, device-pixel scale, or lossless format creates a large artifact.
Fix: capture the viewport or a component when full height is unnecessary, use scale: 'css', and choose JPEG or WebP with an appropriate quality value when lossless output is not required.

Performance, reliability, and operating cost
Browser startup is often the most expensive part of a one-off script. For batches, keep one browser process open and create separate pages or contexts as appropriate for isolation. Reuse a page only when shared state cannot contaminate the next capture. Set navigation and operation timeouts that match your site instead of allowing a job to hang indefinitely, and always close the browser in a finally block in production code.
Full-page images consume more memory than viewport images, especially at device scale. Limit concurrency when capturing many long pages, and stream or upload buffers promptly rather than retaining every image in memory. Treat screenshots as build artifacts: name them deterministically, record the URL and viewport that produced each file, and retain failed-run output long enough to diagnose the cause.
Playwright itself does not charge per screenshot; your costs come from the machine, CI minutes, browser storage, bandwidth, and any external service you add. A self-hosted browser gives control over environment and data, while a screenshot API can remove browser installation and maintenance from your workflow.
Or skip the browser setup
ScreenshotNeo is a website screenshot API and MCP server for developers. One GET request returns a PNG, JPEG, WebP, or PDF. It accepts cookie and consent banners like a visitor, then removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; each cleanup step can be turned off. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits are not billed, and each response reports the result in X-Page-Verdict and X-Billed headers.
Here is the one-call cURL form (see the ScreenshotNeo API documentation for all parameters):
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpThe same request in Python:
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)And in Node.js:
const q = new URLSearchParams({ access_key: 'YOUR_API_KEY', url: 'https://stripe.com' });
const res = await fetch(`https://api.screenshotneo.com/v1/shot?${q}`);ScreenshotNeo exposes 63 options, including full-page capture with lazy images loaded, CSS-selector element capture, dark mode, 12 device presets plus arbitrary viewports, retina scale, PDF paper size/margins/orientation/page ranges, HTML or CSS to image, custom JavaScript and CSS, pre-capture clicks, hidden selectors, waits for selectors/delays/network idle, ad/tracker/request/resource blocking, custom headers/cookies/user agents and Authorization, timezone and geolocation, transparent backgrounds, resizing, chosen cache TTLs, signed links for public <img> tags, asynchronous jobs with signed webhooks, bulk capture of up to 100 URLs per call, a usage API, an OpenAPI specification, and compatibility with parameter names used by other screenshot APIs.

Frequently Asked Questions
Can I use a Playwright screenshot buffer without writing a temporary file?
Yes. Omit the path option; page.screenshot() returns the image bytes, which you can upload, hash, or pass to another function directly.
Why should visual baselines be generated in the same environment?
Playwright documents differences caused by the operating system, browser version, settings, hardware, power source, and headless mode. Keeping those variables consistent reduces environment-only diffs that are unrelated to your page.
