Short answer: Cypress is the more turnkey choice when screenshots are part of JavaScript or TypeScript end-to-end tests. Its cy.screenshot() command captures pages, elements, and test-runner views, and cypress run saves a failure screenshot automatically by default. Selenium is a lower-level, highly portable WebDriver capability: the browser returns a Base64-encoded image, and your test code decides how to save, name, crop, compare, and retain it. Neither core API compares images, so visual regression requires a plugin or external service.
What each framework actually captures
| Question | Selenium | Cypress |
|---|---|---|
| Capture API | WebDriver screenshot endpoint, commonly exposed through TakesScreenshot and getScreenshotAs |
cy.screenshot() for the application under test, or cy.get(selector).screenshot() for an element |
| Default artifact location | Your code or test framework chooses it | cypress/screenshots |
| Failure screenshots | You add a listener, hook, or teardown handler | Captured automatically during cypress run when screenshotOnRunFailure is enabled (the default) |
| Built-in image comparison | No | No; Cypress explicitly says it does not perform image comparison itself |
| Browser and language reach | WebDriver drivers and grid infrastructure across languages, desktop browsers, and mobile automation | JavaScript/TypeScript test runner controlling a real browser; Chrome-family browsers and Firefox are documented, with WebKit experimental |
Selenium’s official documentation describes the endpoint as returning a screenshot encoded in Base64 (Selenium screenshot documentation). Cypress documents screenshots for both interactive and headless runs (Cypress screenshot command).

Java: save a PNG from WebDriver
This complete example opens a page, waits for a visible element, and writes the browser image to a timestamped file. The driver must already be available on your classpath and configured for the browser you run.

public class Capture {
public static void main(String[] args) throws Exception {
WebDriver driver = new ChromeDriver();
try {
driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(5));
driver.get("https://example.com");
new WebDriverWait(driver, Duration.ofSeconds(15))
.until(ExpectedConditions.visibilityOfElementLocated(By.tagName("h1")));
Path output = Path.of("artifacts", "example.png");
Files.createDirectories(output.getParent());
byte[] png = ((TakesScreenshot) driver).getScreenshotAs(OutputType.BYTES);
Files.write(output, png);
} finally {
driver.quit();
}
}
}OutputType.FILE is useful when a framework expects a temporary file; OutputType.BASE64 gives you the encoded string directly. The endpoint and driver determine the supported image format, so treat PNG as the interoperable default unless your driver documents another option.

Full-page and element captures
A normal WebDriver screenshot is generally the current viewport. Full-page behavior differs by browser and driver, so do not assume that setting a tall window produces a reliable full document image. For a specific component, locate the element and use the driver’s element screenshot support where available, or crop the captured image in your own pipeline. This lower-level approach is flexible, but you must define scrolling, lazy loading, clipping, and naming rules yourself.
Adding failure artifacts
Register a framework hook (for example, a JUnit extension or TestNG listener) that checks whether a test failed, calls getScreenshotAs, and writes a path containing the test name, browser, and build identifier. Capture page source and browser logs in the same hook if your diagnosis process needs them. Ensure the hook runs before the driver is quit; otherwise there is no live session from which to capture.
Taking screenshots with Cypress
Capture a page or an element
describe('checkout', () => {
it('captures the confirmation page', () => {
cy.visit('https://example.com/checkout');
cy.get('[data-testid="confirmation"]').should('be.visible');
cy.screenshot('checkout-confirmation', {
capture: 'fullPage',
blackout: ['.customer-email', '.live-chat']
});
});
it('captures one component', () => {
cy.get('.order-summary').screenshot('order-summary');
});
});Files go to cypress/screenshots by default. Cypress clears that folder before cypress run unless trashAssetsBeforeRuns is changed, so configure CI artifact retention if you need screenshots after a job ends.
Important screenshot options
Cypress supports capture: 'viewport', 'fullPage', and 'runner'. Failure screenshots are coerced to the runner view. Other documented controls include:

blackoutto hide selectors containing personal or unstable data.overwriteto control whether an existing file is replaced (the default is false).disableTimersAndAnimations, true by default, to reduce moving content while the image is taken.screenshotOnRunFailure, true by default, to disable automatic failure captures when set to false.
Use a stable name and deterministic selectors. If a page contains rotating adverts, timestamps, or animated canvases, blackout or disable those regions before comparing images.
Browser execution
Cypress launches a real browser in an isolated state. Its documented browser support includes Chrome-family browsers (including Edge and Chrome for Testing) and Firefox; WebKit support is experimental (Cypress browser documentation). Pin the browser version in CI when pixel-level consistency matters.
Which is better for visual regression?
Neither Selenium nor Cypress is a complete visual-regression system. A screenshot is only the capture stage. You also need a baseline store, a pixel or perceptual comparison, a difference image, approval workflow, and retention policy. Cypress states this boundary directly: “Cypress does not perform image comparison itself” (Cypress visual-testing documentation).
A reliable comparison workflow
- Fix the viewport, device scale, browser version, operating system, fonts, locale, timezone, and test data.
- Wait for the UI state you intend to approve: network completion alone may not mean fonts or lazy images are ready.
- Mask changing content such as IDs, dates, avatars, ads, and chat controls.
- Capture with the same dimensions and naming convention on every run.
- Compare against an approved baseline using a visual-testing plugin or service.
- Publish the diff and require a human approval for intentional design changes.
Operating systems, browser versions, display scaling, and fonts can change pixels even when the application is correct. Set a small, justified difference threshold rather than hiding broad layout regressions with a permissive threshold.

Selenium or Cypress: decision guide
Choose Cypress when
- Your tests are JavaScript or TypeScript and you want screenshot commands beside assertions.
- Element, full-page, and runner captures should work with little custom plumbing.
- Automatic screenshots on headless test failure are valuable in CI.
- You can standardize on Cypress’s supported browser workflow.
Choose Selenium when
- Your organization needs Java, Python, C#, JavaScript, or another WebDriver language.
- You already operate Selenium Grid, cloud browsers, or a custom driver matrix.
- You need low-level control over capture timing, storage, naming, cropping, and artifact handling.
- The same automation layer must cover desktop and mobile WebDriver infrastructure.
Use an external visual service when
Baseline approval, reviewable diffs, parallel browser coverage, or long-term artifact management matters more than owning comparison code. Keep capture and comparison separate so a failed page load is not mistaken for a legitimate visual change.
Reliability, performance, and cost considerations
- Synchronization: wait for a meaningful selector and stable content. A screenshot taken before fonts, images, or client-side data arrive creates false differences.
- Viewport consistency: set width, height, and device scale explicitly in both frameworks.
- Isolation: clear cookies and storage or use a fresh context when state can alter the image.
- Artifacts: store screenshots, diffs, test metadata, and the browser version together; prune large historical sets according to your retention policy.
- Parallel runs: include browser, viewport, and test identifiers in filenames to prevent collisions.
- Cost: Selenium and Cypress are framework components; infrastructure, browsers, CI minutes, storage, and any comparison service are separate expenses. No cited source establishes a performance or adoption advantage for either framework.
Common problems and fixes
The screenshot is blank or incomplete
Usually the page was captured before navigation or rendering finished. Wait for a visible application selector, verify the URL, and ensure lazy-loaded content has entered the viewport. For Selenium, confirm the driver session is still alive when the hook runs.
Only the viewport appears, not the whole page
Selenium’s basic screenshot is a WebDriver capture primitive, not a universal full-page command. Use browser-specific full-page support or compose a scroll-and-stitch routine. In Cypress, set capture: 'fullPage' and check that fixed headers or infinite-scroll content are handled intentionally.
Cypress overwrote or removed an artifact
Give captures unique names, set overwrite: false when appropriate, and remember that cypress run clears the screenshots directory by default. Upload artifacts before the CI workspace is destroyed, or adjust trashAssetsBeforeRuns.

Every visual test fails after a browser update
Pin browser and operating-system images, install identical fonts, fix device scale, and regenerate baselines only after reviewing the diffs. Do not approve a wholesale baseline change without checking for layout or accessibility regressions.
Failure screenshots contain secrets
Use Cypress blackout selectors or redact images in your Selenium artifact pipeline. Avoid putting tokens in URLs, test data, or filenames, and restrict CI artifact access.

Frequently Asked Questions
Does Cypress compare screenshots by itself?
No. Cypress captures images, but baseline comparison, diff review, and approval require a plugin or external integration.
Can Selenium take screenshots in languages other than Java?
Yes. Selenium exposes the WebDriver capability through language bindings; the Java example uses the documented pattern, while storage and failure hooks remain your responsibility.
Why do identical screenshots differ in CI?
Browser and operating-system versions, fonts, display scaling, locale, animations, and changing application data can all alter pixels. Standardize those inputs and mask dynamic regions.
