What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
For an ordinary cookie banner rendered in the webpage, identify and click the site’s actual consent control, wait until the banner is hidden, and then call page.screenshot(). The banner’s selector and button label depend on the site; Puppeteer does not provide a universal cookie-banner selector. The example below is a pattern to adapt, not a drop-in selector for every site.
Dismiss an in-page cookie banner before taking a screenshot
- Navigate to the page and allow its content and consent interface to load. There is no single navigation wait condition that works for every site.
- Inspect the consent UI and identify the relevant button by its accessible name, visible text, or a stable selector. Puppeteer supports CSS selectors and documents text and accessibility selector syntax. Prefer a selector grounded in the actual page rather than guessing a class or assuming the button says “Accept.”
- Use a locator to click the control. Puppeteer recommends locators for page interaction; their actions wait for readiness conditions such as visibility, enabled state, viewport placement, and bounding-box stability, and retry when an action cannot yet proceed.
- Wait for the banner to become hidden using its real selector. Do not treat a completed click as proof that the overlay has disappeared.
- Capture only after dismissal is confirmed.
Illustrative Puppeteer pattern (replace url, the button test, and the banner selector with details observed on your target page):
await page.goto(url);
await page.locator('button').filter(button => button.textContent?.trim() === 'Accept').click();
await page.waitForSelector('[data-cookie-banner]', { hidden: true });
await page.screenshot({ path: 'page.png' });This assumes a button whose text is exactly “Accept” and a banner matching [data-cookie-banner]. Neither is a Puppeteer standard. If you need a failure to be explicit, let the hidden-selector wait time out and handle that timeout rather than silently saving a screenshot that still contains the banner.
Choose a selector that matches the real consent UI
Prefer stable, meaningful controls
Use the control the site actually presents, such as a button with an accessible name or a stable attribute, and verify that your selector targets the intended choice. A broad selector like button alone can match multiple controls; filtering by observed text is illustrative but can also be brittle if wording or whitespace differs.
Account for asynchronous rendering
The banner may appear after navigation or after other page content loads. Select and wait based on the target site’s observed behavior. Do not assume that one fixed delay or one navigation wait mode covers every consent implementation.
Verify dismissal before capture
page.waitForSelector(selector, { hidden: true }) is a documented way to wait until a selector is hidden. Use the actual banner selector and a timeout appropriate to the page. If the wait fails, investigate whether the selector is wrong, the click did not take effect, or the page did not reach the expected state.
Cookie banners are not browser-native JavaScript dialogs
A typical consent banner is HTML rendered inside the page, so interact with it as a page element using a locator or selector. Puppeteer’s separate Dialog API handles browser-native JavaScript dialogs dispatched through the page’s dialog event, such as alerts or prompts; its accept() and dismiss() methods are not the normal way to close an in-page cookie banner.
Capture the page or just one element
After the banner is confirmed hidden, page.screenshot() captures the page. If your goal is a particular element rather than the full page, Puppeteer also supports ElementHandle.screenshot(). Choose the capture target based on what the screenshot needs to show.
Recommended Free Tools
Troubleshoot a banner that remains in the screenshot
- The click times out or does nothing: Confirm that the selector matches the visible consent control and that its label or attributes match the page. Check whether the intended control is enabled and whether another overlay blocks it.
- The wait for hidden times out: Confirm the banner selector against the rendered page. The banner may use a different element, remain visible after the chosen action, or have appeared asynchronously.
- The screenshot is taken too early: Ensure the hidden-state wait completes before calling
page.screenshot(). A click finishing alone does not verify that the banner has gone. - You used
page.on('dialog')for an HTML banner: Switch to a locator or selector interaction. Reserve the Dialog API for browser-native JavaScript dialogs. - Your selector works on one site but not another: Consent markup and wording vary by site. Inspect each target and avoid treating an example selector as universal.
Or skip the browser setup
For a one-call screenshot without managing Puppeteer setup, try ScreenshotNeo. It accepts cookie/consent banners like a visitor and removes 60+ known consent platforms, newsletter popups, and chat widgets before capture; each step can be turned off. Bot checks/CAPTCHAs, blank pages, timeouts, failed loads, and cache hits cost nothing, and responses identify the page verdict and billing status in headers. Its MCP server gives AI agents tools for screenshots, page information, and PDF capture. The free plan includes 1,000 shots a month with no card; paid plans start at $5 for 3,000 shots.

Frequently Asked Questions
Does Puppeteer have a universal cookie-banner selector?
No. Inspect the target page and use its actual consent control and banner selector.
Why doesn’t Puppeteer’s Dialog API close my cookie banner?
That API handles browser-native JavaScript dialogs. Most cookie banners are page elements and should be handled with locators or selectors.
