For example:
const spinner = page.getByTestId('loading-spinner');
await spinner.waitFor({ state: 'visible' });
await spinner.screenshot({ path: 'spinner.png', animations: 'allow' });Replace loading-spinner with your application’s actual test ID or another reliable locator. This captures the spinner element rather than the entire page.
Use a locator, an explicit visibility wait, and an element screenshot
A spinner can appear asynchronously and disappear as soon as an operation finishes. Playwright’s locator screenshot waits for actionability, scrolls the element into view, and fails if the element detaches before the image is taken. It does not, however, prove that a spinner that has not appeared yet will appear. Express that condition yourself:
import { test } from '@playwright/test';
test('captures the loading spinner', async ({ page }) => {
await page.goto('https://example.test');
const spinner = page.getByTestId('loading-spinner');
await spinner.waitFor({ state: 'visible' });
await spinner.screenshot({
path: 'artifacts/spinner.png',
animations: 'allow'
});
});If the spinner only starts after a click or form submission, perform that action first and then wait for the resulting visible state. Do not wait for the operation to finish before taking the image, because the spinner may already be gone.

Choose a locator that identifies the actual spinner
Playwright provides built-in locators such as getByRole, getByText, getByLabel, getByPlaceholder, getByAltText, getByTitle, and getByTestId. Prefer the one that expresses how a user or an accessibility tree identifies the element.
Test ID
const spinner = page.getByTestId('loading-spinner');A dedicated test ID is often the least ambiguous choice for a purely visual loader. Add it to the spinner element in your application markup.
Accessible role or label
const spinner = page.getByRole('status', { name: /loading/i });
// or
const spinner = page.getByLabel('Loading');Use the role and accessible name your markup actually exposes. A CSS selector copied from a generated class can break when the UI is rebuilt.
CSS locator as a last resort
const spinner = page.locator('[data-state="loading"] .spinner');Scope broad selectors to the relevant component and verify that they match exactly the intended element. If multiple elements match, use a more specific locator or an appropriate filter.

await spinner.waitFor({ state: 'visible' });This waits for the element to be attached and visible. Other states are useful when your test has a different objective:
state: 'attached'waits for a DOM node even if it is not visible.state: 'hidden'waits for the loading indicator to be hidden.state: 'detached'waits until the node is removed.
page.waitForSelector() is discouraged in the Page API documentation in favor of locator waits and web-first assertions. Playwright generally auto-waits before actions, but that auto-wait is not an assertion that a transient spinner has appeared.
Triggering the spinner
const spinner = page.getByTestId('loading-spinner');
await page.getByRole('button', { name: 'Load report' }).click();
await spinner.waitFor({ state: 'visible' });
await spinner.screenshot({ path: 'report-loading.png' });If the request completes so quickly that the spinner never becomes visible, decide what your application contract should be. You may need to control the test response, add a test-only synchronization hook, or assert the completed state instead. No generic timeout can determine that application-specific intent.

animations: 'allow' is Playwright’s documented default and leaves the spinner moving. It is the correct choice when the screenshot must represent the animated loading state:
await spinner.screenshot({ path: 'spinner.png', animations: 'allow' });With animations: 'disabled', finite animations are fast-forwarded and infinite animations are canceled to their initial state during capture, then played again. A circular loader can therefore look frozen, empty, or unlike what a user sees:

Element screenshot versus page screenshot
| Method | What it captures | Best use |
|---|---|---|
locator.screenshot() |
The matched spinner element | One-off evidence or a focused image of the loader |
page.screenshot() |
The viewport or full page, depending on options | Spinner plus surrounding layout, overlay, and page context |
expect(locator).toHaveScreenshot() |
A locator image used in a visual assertion | Playwright Test visual regression checks |
Capture the surrounding page
await page.screenshot({
path: 'loading-page.png',
fullPage: false
});Use a page screenshot when the position of the loader, a dimmed background, or an overlay is part of what you need to inspect. A correct element locator does not make a covered element visible in the resulting image.

Use a visual regression assertion
import { test, expect } from '@playwright/test';
test('spinner visual stays consistent', async ({ page }) => {
await page.goto('https://example.test');
const spinner = page.getByTestId('loading-spinner');
await page.getByRole('button', { name: 'Load report' }).click();
await spinner.waitFor({ state: 'visible' });
await expect(spinner).toHaveScreenshot('spinner.png');
});toHaveScreenshot is provided by the Playwright Test runner. It waits for two consecutive locator screenshots to match before comparing them with the stored expectation, which helps avoid saving a frame while layout is still changing.

});Troubleshoot missing or incorrect spinner images
The screenshot is taken before the spinner appears
Symptom: the file is empty, the locator times out, or the captured state is already complete. Fix it by waiting for state: 'visible' immediately after the action that starts loading. If the operation can finish instantly, control the test data or test the completed state instead.
The locator matches nothing or the wrong element
Inspect the rendered accessibility tree and DOM, then choose a stable test ID, role, label, or text locator. Generated class names and selectors copied from a single run are especially fragile. Narrow a locator that matches several nodes.

The spinner detaches during capture
Locator screenshots throw when the element is removed before capture. Coordinate the screenshot with the loading phase: trigger loading, wait for visibility, and capture without an unnecessary intermediate delay. If the product intentionally replaces the node, add a stable loading container or a test hook.
An overlay covers the spinner
An element can satisfy the locator while another element paints over it. Capture the page to inspect stacking and overlays, or fix the application’s z-index and visibility behavior. Do not use forced interaction as a substitute for a screenshot that should show what a user sees.
The animation looks frozen
Check that you did not pass animations: 'disabled'. Infinite animations are canceled to their initial frame for that capture mode. Use animations: 'allow' when motion is part of the evidence.
The visual assertion is flaky
Wait for the spinner’s visible state, keep viewport and browser settings consistent, and avoid capturing while surrounding layout is still changing. The assertion’s consecutive-image stabilization helps, but it cannot repair an unstable application state or a locator that changes between frames.

Or skip the browser setup
If you need a URL screenshot rather than a Playwright test artifact, ScreenshotNeo provides a GET API and an MCP server. It accepts cookie and consent banners before capture and removes more than 60 known consent platforms, newsletter popups, and chat widgets; each cleanup step can be disabled. 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 tools—take_screenshot, get_page_info, and capture_pdf—work with Claude, Cursor, and other MCP clients.
The API can capture PNG, JPEG, or WebP. Options include full-page and CSS-selector element capture, dark mode, device presets or custom viewports, retina scale, PDF paper and page settings, custom CSS and JavaScript, clicks, waits, blocked resources, headers, cookies, user agent, authorization, timezone, geolocation, transparent backgrounds, resizing, chosen cache TTL, signed image links, asynchronous webhooks, bulk capture of up to 100 URLs per call, usage data, and an OpenAPI specification.

Frequently Asked Questions
Can I capture a spinner that is already hidden?
No. A visibility wait requires the element to become visible. Trigger the loading state first or test the application’s completed state instead.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsShould I use a fixed timeout before the screenshot?
Use a locator wait for the visible loading state. A fixed delay can be too short on a slow run and unnecessarily long on a fast one.
Why does my spinner screenshot contain only its initial frame?
The capture likely used animations: 'disabled'. Use animations: 'allow' when the moving indicator must remain representative.
