Use Playwright to save the viewport, the entire scrollable page, or one element; use html2canvas when client-side DOM-to-canvas rendering is acceptable and you can tolerate differences from actual browser pixels.
Choose how to turn HTML into an image
There are two distinct approaches. Browser automation renders the page in a browser and captures its output. A DOM-to-canvas library reads elements and styles, then reconstructs an image in the browser. Choose based on whether visual fidelity or browser-side image generation matters more.

| Approach | What it produces | Best fit | Important limitation |
|---|---|---|---|
| Playwright screenshot | Browser-rendered page, viewport, full page, or element | Website screenshots and browser-based capture workflows | Results can vary by operating system, browser version, settings, hardware, power source, and headless mode. |
| html2canvas | A canvas reconstructed from DOM and applied styles | Client-side image generation when a reconstruction is adequate | It is not a native screenshot; CSS support and cross-origin content can limit fidelity. |
Playwright’s screenshot guide covers file output, screenshot bytes, full-page capture, and locator capture. Its Page screenshot API documents options such as fullPage and transparent backgrounds. For visual comparisons, consult the Playwright visual comparisons guide. The html2canvas project documentation explains the DOM-based rendering model and its limitations.

Capture a website screenshot with Playwright
Install Playwright and its browser binaries in the project, then create a script such as screenshot.mjs. This example sets the viewport before navigation so the page uses the intended responsive layout, waits for the page’s load event, and saves a viewport screenshot:
import { chromium } from 'playwright';
const browser = await chromium.launch();
const page = await browser.newPage({
viewport: { width: 1440, height: 900 },
});
try {
await page.goto('https://example.com', { waitUntil: 'load' });
await page.screenshot({ path: 'page.png' });
} finally {
await browser.close();
}Run it with node screenshot.mjs. The screenshot is written to page.png. Change the viewport dimensions to control the layout; set them before navigation when the responsive breakpoint should be applied from the start. The file extension determines the output format for path-based screenshots, so use an appropriate supported extension such as .png or .jpeg.
Return screenshot bytes instead of saving a file
When another step in your application needs the image data, omit path and retain the returned buffer:
const imageBytes = await page.screenshot({ type: 'png' });You can pass imageBytes to your own storage, response, or image-processing code. The exact downstream handling depends on your application.

Set fullPage: true to capture the entire scrollable page rather than only the current viewport:
await page.screenshot({ path: 'full-page.png', fullPage: true });Playwright captures the page as though it were shown on a very tall screen. This is useful for a long article or landing page, but it is not a sequence of viewport-sized screenshots. If the page loads content only as it is scrolled, check whether all intended content has appeared before capturing; a screenshot cannot include content the page has not rendered.
How do I take a screenshot of a single element?
Locate the target element and call screenshot() on its locator:
const card = page.locator('.product-card').first();
await card.screenshot({ path: 'product-card.png' });Replace .product-card with a selector that identifies the element you want. If the selector matches multiple elements, use a locator method such as first() to choose one deliberately. Locator screenshots capture the selected element rather than the entire page.

How to render an element with html2canvas
Use html2canvas in a browser when you want a canvas generated from a DOM element and its styles. It is not interchangeable with a screenshot of browser pixels: the project describes the output as a reconstruction based on page information, and notes that it may not be fully accurate to the real representation.
import html2canvas from 'html2canvas';
const element = document.querySelector('#capture');
if (!element) throw new Error('Element #capture was not found');
const canvas = await html2canvas(element);
const imageUrl = canvas.toDataURL('image/png');
const link = document.createElement('a');
link.href = imageUrl;
link.download = 'element.png';
link.click();Run this code in a browser context after the target element exists in the DOM. The canvas can also be passed directly to browser-side processing rather than downloaded. html2canvas is browser-dependent and its documentation says it is unsuitable for Node.js use. CSS support depends on properties implemented by the project, so check your specific page if the output must closely match the browser.
Cross-origin images and other assets
html2canvas does not bypass browser content-policy restrictions. Cross-origin images or other resources may be unavailable to the canvas unless they are served with suitable permissions or made accessible through a proxy. The project documentation describes using a proxy that returns a base64 data URI. If assets are missing or taint the canvas, verify each resource’s origin and access policy; do not assume the renderer can capture content the browser is not allowed to expose.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Make screenshots more repeatable
For visual regression checks, Playwright Test can create a screenshot baseline on the first run and compare later captures against it. A changed image does not necessarily mean your application code changed: screenshots may differ with the host operating system, browser version, settings, hardware, power source, or headless mode.
- Keep the capture environment consistent with the one used to create the baseline.
- Control the viewport and page state so the same layout is rendered each run.
- Suppress or otherwise control dynamic content when deterministic comparisons matter.
- Treat environment changes as potential causes of visual differences before attributing them to an application regression.
See the Playwright visual comparisons documentation for its baseline workflow and environment cautions.
Common problems and fixes
- The screenshot has the wrong layout: Set the viewport dimensions before navigation. A different viewport can select a different responsive breakpoint.
- The full-page image omits content: Confirm that the content has loaded and rendered before capture, especially on pages that defer content until scrolling.
- The element capture fails or targets the wrong thing: Check that the selector matches an element on the page and explicitly choose an element if the selector matches more than one.
- html2canvas differs from the browser view: The library reconstructs output from DOM and styles rather than taking a native screenshot. Check CSS support and test the specific page.
- Images are absent from html2canvas output: Check cross-origin permissions and whether the resources need to be served through an appropriate proxy.
- Visual comparisons vary between runs: Keep the browser and host environment consistent, and control dynamic page content.
Or skip the browser setup
ScreenshotNeo offers a one-request screenshot API. The examples below use its documented endpoint; see the ScreenshotNeo API documentation for parameters and response details.
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpThe response is an image or PDF according to the request options. ScreenshotNeo accepts cookie or consent banners like a visitor and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; each step can be turned off. Bot checks and CAPTCHAs, blank pages, timeouts, failed loads, and cache hits are not billed, and the response reports the page verdict and billing status in headers. Its MCP server provides take_screenshot, get_page_info, and capture_pdf for Claude, Cursor, and other 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 html2canvas run in Node.js?
The html2canvas project describes the library as browser-dependent and unsuitable for Node.js. Use browser-based execution for that approach.
Can a screenshot have a transparent background?
Playwright’s screenshot API supports transparent-background output except for JPEG; choose an output format that supports transparency.
