To scroll the document and capture the resulting viewport, call window.scrollTo() inside page.evaluate(), then take the screenshot:
await page.evaluate(() => window.scrollTo(0, 600));
await page.screenshot({ path: 'page.png' });Change 600 to the vertical position you need. If the page scrolls inside a nested element instead of the document, scroll that element with a Puppeteer locator.

Scroll the document before capturing its viewport
Page.evaluate() runs a function in the page context, so it can call the browser’s window.scrollTo() API. Puppeteer’s Page.screenshot() then captures the page. The following example assumes page is an already-open Puppeteer page:
await page.evaluate(() => window.scrollTo(0, 600));
await page.screenshot({ path: 'page.png' });The two arguments to window.scrollTo(x, y) are horizontal and vertical scroll coordinates in CSS pixels. This sets the document’s scroll position; it does not mean “scroll down by 600” from wherever the page currently is. For a relative movement, read the current position in the page and add the desired amount:

await page.evaluate(() => window.scrollTo(0, window.scrollY + 600));
await page.screenshot({ path: 'page.png' });Use a viewport screenshot when you want the visible area after scrolling. Puppeteer’s fullPage screenshot option defaults to false, so the ordinary screenshot is not automatically the whole document. The official API reference documents these screenshot behaviors: Page screenshot options.
Scroll a nested container instead
Many applications keep a panel, feed, or modal independently scrollable while the document itself stays in place. In that case, target the scrollable element rather than calling window.scrollTo():
await page.locator('.scroll-container').scroll({ scrollTop: 600 });
await page.screenshot({ path: 'page.png' });Replace .scroll-container with a selector for the actual scrollable element. Puppeteer’s Locator.scroll() uses mouse-wheel events and accepts scrollTop and scrollLeft values. Its locator checks that the target is visible and has a stable bounding box across two animation frames before scrolling. See Locator.scroll().

Use an element handle’s screenshot method when you need only a particular element. Puppeteer documents that ElementHandle.screenshot() scrolls the element into view if necessary, then captures that element:
const element = await page.waitForSelector('.report-card');
if (!element) throw new Error('Report card not found');
await element.screenshot({ path: 'report-card.png' });Because the method scrolls its target into view, an explicit document scroll may be unnecessary for this case. See ElementHandle.screenshot().

Wait when scrolling triggers page changes
Scrolling can trigger lazy content, animations, or other asynchronous changes. A scroll call by itself does not establish that the content is ready for capture. Wait for a condition that reflects the page’s actual state, such as a known element appearing or a loading indicator disappearing:
await page.evaluate(() => window.scrollTo(0, 600));
await page.waitForFunction(() => {
const loading = document.querySelector('.loading-indicator');
return !loading;
});
await page.screenshot({ path: 'page.png' });Replace .loading-indicator with a condition meaningful to the page. If a loading indicator is not present, wait for an observable signal the page provides rather than assuming a fixed delay will always be sufficient.

Common problems and fixes
- The screenshot shows the top of the page. Confirm the scroll completed before taking the screenshot, and check whether the page or a nested container is the intended scroll target.
- The wrong amount of content moves.
window.scrollTo(0, 600)sets an absolute document position. Usewindow.scrollY + amountfor a relative document movement, or use the nested container’s locator when that element owns the scroll. - The desired content is missing even though the page scrolled. Scrolling may have triggered asynchronous loading. Wait for a page-specific readiness condition with
waitForFunction()before capturing. - The image includes more than the visible viewport. Check that
fullPageis not set totrue; that option captures the full document. - The locator does not scroll the expected panel. Check that the selector matches the visible scrollable element and that it is the panel containing the target content.
- The element screenshot changes the page position. This is expected when the target needs to be brought into view;
ElementHandle.screenshot()scrolls its target into view when needed.
