The examples below use the current Puppeteer API documented for the 25.x series.
What you need before taking a screenshot
- Node.js installed on your development machine.
- A project with Puppeteer installed:
npm install puppeteer. - A URL that your local browser can load.
Puppeteer downloads a compatible browser when installed. If your project uses a separately managed browser, configure its executable path according to your Puppeteer setup.
How do I take a screenshot with Puppeteer?
The basic sequence is: launch a browser, create a page, navigate to the URL, call page.screenshot(), then close the browser. Puppeteer’s official guide demonstrates this flow at pptr.dev/guides/screenshots.
import puppeteer from 'puppeteer';
const browser = await puppeteer.launch();
try {
const page = await browser.newPage();
await page.goto('https://example.com');
await page.screenshot({ path: 'screenshot.png' });
} finally {
await browser.close();
}path saves the image to disk. A relative path is resolved from the process’s current working directory. Without path, Puppeteer returns the image data instead of writing a file. The default return value is a Uint8Array; set encoding: 'base64' when you need a Base64 string. See the Page.screenshot() reference.

How do I take a full page screenshot in Puppeteer?
Set fullPage: true. The documented default is false, which captures the current viewport.
await page.screenshot({
path: 'full-page.png',
fullPage: true
});For pages that render content as you scroll, full-page capture requests the complete document, but it does not guarantee that every application has finished its own asynchronous rendering. Wait for a meaningful selector or application state when necessary.
Wait for navigation and page content
The screenshots guide shows waitUntil: 'networkidle2' as one navigation option:

- THE PERFECT VIEW: The 178/178 degree extra wide viewing angle prevents the shifting of colors when viewed from an offset angle, so you always get consistent colors
await page.goto('https://example.com', { waitUntil: 'networkidle2' });This means Puppeteer waits for a period with no more than two active network connections. It is a documented choice, not a universal signal that all images, animations, or client-side data are finished. For dynamic pages, combine navigation with a selector-specific wait such as await page.waitForSelector('.hero').
How do I screenshot an element with Puppeteer?
Locate the target with page.waitForSelector() or another locator, then call ElementHandle.screenshot(). Puppeteer scrolls the element into view if needed. If the element is detached from the DOM before capture, the operation throws an error. The API behavior is documented at ElementHandle.screenshot().
const card = await page.waitForSelector('[data-testid="pricing-card"]');
if (!card) {
throw new Error('Pricing card was not found');
}
await card.screenshot({ path: 'pricing-card.png' });Use a selector that identifies the intended component on your site; a generic selector such as div can match the wrong element or many elements.

Handling elements that rerender
Single-page applications can replace a node after you locate it. Wait for the final state, locate the element again immediately before the screenshot, and capture that fresh handle. If the application intentionally removes the element, treat the detached-element error as a failed capture rather than saving an incomplete image.
Screenshot options that control the output
| Need | Option or method | Behavior |
|---|---|---|
| Save a file | path |
Writes the image to the specified path. The extension can determine the image type. |
| Capture the document | fullPage: true |
Requests the full page instead of only the viewport; default is false. |
| Capture a rectangle | clip |
Captures a specified region using a bounding box. The clip’s optional scale defaults to 1. |
| Choose format | type |
Supported image type selection; documented default is 'png'. |
| Reduce JPEG/WebP size | quality |
Integer/number from 0 to 100. It does not apply to PNG. |
| Transparent background | omitBackground: true |
Hides the default white background and permits transparency; default is false. |
| Return Base64 | encoding: 'base64' |
Returns a Base64 string instead of the default binary Uint8Array. |
| Capture outside the viewport | captureBeyondViewport |
Documented default is false without a clip and true when a clip is supplied. |
Option details and defaults are in Puppeteer’s ScreenshotOptions interface. Clip geometry is described in the ScreenshotClip interface.
Recommended Free Tools
Capture a clipped region
await page.screenshot({
path: 'header-region.png',
clip: { x: 0, y: 0, width: 1200, height: 240, scale: 1 }
});A clip is useful when you know the page coordinates. For a semantic component, an element screenshot is usually less fragile because Puppeteer calculates the element’s bounding box.

Save JPEG or WebP
await page.screenshot({
path: 'page.webp',
type: 'webp',
quality: 80,
fullPage: true
});Quality is meaningful for formats other than PNG. When a path is supplied, choose an extension and, when needed, set type explicitly.
Return bytes for further processing
const bytes = await page.screenshot();
// bytes is a Uint8Array by default
const base64 = await page.screenshot({ encoding: 'base64' });Reliable capture checklist
- Set a deterministic viewport before capture when pixel dimensions matter:
await page.setViewport({ width: 1440, height: 900 });. - Wait for the selector or state that proves the content you need is rendered.
- Use
fullPagefor the whole document, an element handle for a component, andclipfor fixed coordinates. - Choose PNG for lossless output; use JPEG or WebP with an appropriate
qualityvalue when file size matters. - Always close the browser in a
finallyblock so failures do not leave browser processes running.
Common failures and fixes
The screenshot is blank or missing late content
Navigation completion and application rendering are different events. Add a wait for the specific selector or state that indicates the content is ready. A networkidle2 wait can help, but it is not a guarantee for pages with ongoing connections or delayed client-side work.
The selector cannot be found
Confirm the selector matches the loaded document, wait with page.waitForSelector(), and check whether the content is inside an iframe. Content in a cross-origin iframe requires work with that frame’s own page context and permissions.

ElementHandle is detached
The page replaced the node after you located it. Wait for the final UI state, locate the element again, and call screenshot() on the new handle.
The output was not written to disk
Check that you passed path and that the process has permission to write to its directory. If you intentionally omitted path, consume or write the returned Uint8Array yourself.
Concurrent browser work behaves unexpectedly
Some page-creation and closing methods in the same browser context automatically wait while a screenshot is in progress. page.bringToFront() does not wait for an existing screenshot operation. Avoid overlapping operations on the same page unless your workflow accounts for that behavior; see the Page API reference.
Or skip the browser setup
ScreenshotNeo provides a website screenshot API and MCP server when you want a rendered image without maintaining Puppeteer and a browser. One GET request returns PNG, JPEG, WebP, or a PDF.
Quick Recap
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpSee the ScreenshotNeo documentation for request options. Before capture, it accepts cookie or consent banners like a visitor and removes more than 60 known consent platforms, newsletter popups, and chat widgets; each cleanup step can be turned off. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits are not billed, and response headers identify the page verdict and billing status. Its MCP server exposes 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 shots, and every feature is available on every plan. Create a free ScreenshotNeo account.
