To capture an authenticated page without logging in interactively for every run, save the browser context’s storage state after a successful login, restore that state in a new Playwright Java context, verify that the protected page is actually authenticated, and then call Page.screenshot(). Restoring state reuses the session your account already has; it does not bypass the site’s access controls.
Save login state, restore it, and capture the page
Playwright persists authentication at the BrowserContext level. The login flow is site-specific, so complete it through the website’s supported sign-in process and confirm success before writing the state file. The example below shows the API calls and the points where you must supply site-specific login and readiness checks; those steps are deliberately not presented as a universal, tested login recipe.
import com.microsoft.playwright.*;
import java.nio.file.Paths;
public class AuthenticatedScreenshot {
public static void main(String[] args) {
try (Playwright playwright = Playwright.create()) {
Browser browser = playwright.chromium().launch();
// First run: sign in through the site's normal supported flow.
BrowserContext loginContext = browser.newContext();
Page loginPage = loginContext.newPage();
loginPage.navigate("https://example.com/login");
// Complete the site's login flow and verify successful sign-in here.
loginContext.storageState(
new BrowserContext.StorageStateOptions()
.setPath(Paths.get("playwright/.auth/user.json")));
loginContext.close();
// Later run: restore the saved state in a fresh isolated context.
BrowserContext context = browser.newContext(
new Browser.NewContextOptions()
.setStorageStatePath(Paths.get("playwright/.auth/user.json")));
Page page = context.newPage();
page.navigate("https://example.com/account");
// Wait for a reliable, site-specific indicator that the account page is ready.
page.screenshot(new Page.ScreenshotOptions()
.setPath(Paths.get("authenticated-page.png")));
context.close();
browser.close();
}
}
}Replace both example URLs, complete the supported sign-in flow, and add a readiness check tied to the application—for example, a locator unique to the signed-in account view. Navigation completing is not proof that authentication worked: a site may redirect to sign-in or render an unauthenticated page at the requested URL. The example’s placeholder comments must be replaced before it can serve as an end-to-end capture script.
The Java API saves state through BrowserContext.storageState(StorageStateOptions) and restores it through the browser context’s storage-state path option. The screenshot is saved to the given path with Page.screenshot(). See the Playwright Java BrowserContext API, Page API, and authentication guide.

- 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.
Choose the screenshot output you need
Viewport, full page, or a region
By default, a page screenshot captures the visible viewport. Set setFullPage(true) when you need the full scrollable document. For a specific rectangular region, set a screenshot clip rectangle; for one element, use Locator.screenshot(). Full-page images can be substantially taller than viewport captures, so choose based on what the image needs to show.
File, bytes, format, and scale
Set a path to write an image directly to disk, or use the screenshot bytes when you need to post-process the result in memory. Playwright’s screenshot options also support PNG, JPEG, and WebP output, CSS or device scale, animation handling, and locator masks. Scale affects output dimensions; a mask can cover sensitive or variable regions. Choose options deliberately so the saved artifact represents the evidence you intend to preserve. See the Playwright Java screenshots guide and Page API.

Check which browser storage the app uses
Cookies and local storage
Browser context storage state can include cookies and local-storage snapshots. For many applications, that is enough to restore an authenticated session, but the application’s implementation determines what must be present.
IndexedDB, OPFS, and virtual WebAuthn credentials
The Java reference documents options for IndexedDB, the origin private file system (OPFS), and virtual WebAuthn credentials. If the application stores authentication tokens in IndexedDB, enable the IndexedDB snapshot option when saving state. These are versioned capabilities: the Java API marks IndexedDB as added in v1.51, setStorageState in v1.59, virtual credentials in v1.61, and OPFS in v1.63. Confirm your installed Playwright Java version supports any option you plan to use. See the BrowserContext API and Java API version annotations.

Session storage
The standard storage-state API does not persist sessionStorage. If the app depends on it, Playwright’s authentication guide demonstrates serializing the required values and restoring them with context.addInitScript for the matching domain. This is an application-specific workaround: restore only the values the app needs and test the result. See the Playwright authentication guide.
Protect the saved state and the screenshot
A storage-state file can act like a credential. Playwright warns: “The browser state file may contain sensitive cookies and headers that could be used to impersonate you or your test account.” Keep the file in a restricted local or managed secret location, add the auth directory to .gitignore, and do not commit state files to a repository. Prefer a test account with only the access required. Remove or refresh state when it expires or is revoked; the site and account policy determine its lifetime, and Playwright does not provide a universal expiry interval. See the Playwright authentication guide.

Apply the same care to captured images: account pages may expose personal information or secrets. Use a synthetic account where appropriate, and mask or crop sensitive areas before sharing an artifact.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Troubleshoot failed or misleading captures
- The protected URL shows a login page. The state may be missing, expired, revoked, or insufficient for the app’s authentication design. Detect a login redirect or missing account-specific locator, then refresh state through the supported login flow rather than saving a screenshot that looks successful.
- The login succeeds, but the restored context is unauthenticated. Check whether the app relies on IndexedDB or session storage rather than only cookies and local storage. Enable the appropriate version-supported IndexedDB snapshot option if needed; handle session storage separately using the documented, domain-specific initialization approach.
- The screenshot is blank, incomplete, or captures a loading screen. Navigation completion alone does not establish that the application is rendered. Wait for a reliable site-specific readiness indicator before taking the screenshot.
- The saved image omits content below the fold. The default screenshot is the viewport. Enable full-page capture when you need the scrollable document, or capture a specific clip or element when only part of the page is relevant.
- A storage option is unavailable. Verify the Playwright Java version in the project against the API’s version annotations before using newer storage-state features.
- The artifact exposes data that should not be shared. Use a lower-privilege test account, mask or crop the relevant region, or keep the screenshot private.
