What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Use a repeatable URL loop, not a manually operated browser. For maximum control, Playwright automates navigation, waiting, authentication, and screenshots in your own environment. For a declarative command-line job, shot-scraper’s multi command reads a YAML URL list. A hosted batch service is simpler when you want managed browsers, packaged downloads, and failure manifests. Whichever route you choose, define the URL set, viewport, full-page behavior, naming, retries, and privacy requirements before starting.
Plan the batch before you capture
A batch is a controlled repetition of one capture operation. Create an input list that you can preserve and retry, then decide what a successful output means.
- URL scope: normalize schemes and trailing slashes, and decide whether redirects are acceptable. Keep the original URL beside the final URL in your manifest.
- Page state: public pages, authenticated pages, consent banners, lazy-loaded images, animations, and personalized content can all change the result.
- Image scope: choose viewport-only or full-page capture, a CSS element or the entire page, viewport dimensions, device scale, and PNG, JPEG, or WebP.
- Output contract: use deterministic names such as an index plus a safe hostname. Store capture time, settings, final URL, status, and error text.
- Failure policy: decide whether one failed URL stops the job, how many retries are allowed, and where failed inputs are recorded.
Run a small pilot first. Check redirects, login state, lazy content, filename collisions, browser errors, and output dimensions before launching hundreds of URLs.
Option 1: Batch screenshots with Playwright (Node.js)
Playwright gives you browser contexts, custom headers and cookies, scripted clicks, wait conditions, masking, and per-URL error handling. Its Page API documentation describes navigation and screenshot options such as fullPage and masking. The following script reads urls.txt, captures each page, and writes a JSON manifest while continuing after individual failures.

Install the browser runtime
- Install Node.js, then create a project:
mkdir batch-shots && cd batch-shots && npm init -y. - Install Playwright:
npm install playwright. - Download Chromium:
npx playwright install chromium. - Create
urls.txtwith one absolute URL per line.
Runnable capture script
const fs = require('node:fs/promises');
const path = require('node:path');
const { chromium } = require('playwright');
const urls = (await fs.readFile('urls.txt', 'utf8'))
.split(/r?n/).map(s => s.trim()).filter(Boolean);
await fs.mkdir('shots', { recursive: true });
const browser = await chromium.launch();
const context = await browser.newContext({
viewport: { width: 1440, height: 900 },
deviceScaleFactor: 1
});
const results = [];
for (const [index, url] of urls.entries()) {
const filename = `${String(index + 1).padStart(4, '0')}.png`;
const started = new Date().toISOString();
const page = await context.newPage();
try {
const response = await page.goto(url, {
waitUntil: 'networkidle',
timeout: 60000
});
await page.screenshot({
path: path.join('shots', filename),
fullPage: true,
animations: 'disabled'
});
results.push({ inputUrl: url, finalUrl: page.url(), status: response?.status() ?? null, file: filename, started });
} catch (error) {
results.push({ inputUrl: url, finalUrl: page.url(), error: String(error), started });
} finally {
await page.close();
}
}
await fs.writeFile('manifest.json', JSON.stringify(results, null, 2));
await context.close();
await browser.close();Run it with node capture.js. The script uses one browser and context, but creates a fresh page per URL so page state does not leak between captures. Add bounded concurrency only after the serial version is reliable; excessive parallel tabs can exhaust CPU, memory, file descriptors, or a target site’s rate limits.
Adapt Playwright for real pages
- Authentication: create a context with
storageState, cookies, or anAuthorizationheader. Never put credentials inurls.txtor a checked-in script. - Dynamic content: replace broad
networkidlewaits withpage.waitForSelector()for a known element, or use a documented delay when the page has continuous analytics traffic. - Consent and overlays: click the site’s accept button before capture, or hide a known selector. Mask volatile regions when using visual comparisons.
- One element: locate it with
page.locator('main').screenshot({ path: 'main.png' }). - Retries: retry timeouts and transient network errors with increasing delays; do not blindly retry authentication failures or persistent 4xx responses.
Option 2: Use shot-scraper for a declarative CLI batch
shot-scraper is useful when the job is primarily “open these URLs and save images.” Its release 0.14.3 documentation describes YAML input, the multi command, output naming, retina captures, a no-clobber option, and fail-on-error behavior. Verify the current release before installing because command details can change.
- Install the package:
pip install shot-scraper. - Install its browser:
shot-scraper install. - Create
pages.ymlusing the URL list format documented for your installed release. - Run the documented
shot-scraper multicommand, selecting an output directory and any full-page, retina, no-clobber, or fail-on-error options you need.
Keep the YAML file under version control with the capture date and intended viewport. This approach is less suitable when every URL needs a different login flow or custom interaction; use Playwright for those cases. The reference documentation is available at shot-scraper 0.14.3 documentation.
Option 3: Hosted batch screenshot services
A hosted service removes browser installation and maintenance. url2image says it accepts pasted URLs, CSV/text uploads, or JSON, opens each URL in a real headless browser, and returns a ZIP containing one image per URL, a manifest, and not-rendered.csv. It advertises up to 500 URLs per batch, retries failed URLs once, and returns credits when no screenshot exists. These are the provider’s published terms, not an independent performance benchmark.

ScreenshotRun’s documentation search excerpt advertises up to 100 URLs per batch and requires Pro or above; verify the current terms at its batch documentation before relying on them. Hosted limits, concurrency, retention, and authentication support vary, so inspect current documentation and privacy policies before sending sensitive pages.

Make captures reproducible
For visual regression, identical input does not guarantee identical pixels. Playwright explains that rendering varies with operating system, browser, hardware, fonts, and settings, and recommends using the same environment that produced the baseline. Its visual-comparison guidance is at the Playwright snapshots documentation.
- Pin the browser version and run in the same container or CI image.
- Keep viewport, device scale factor, fonts, locale, timezone, color scheme, and reduced-motion settings fixed.
- Disable animations or wait for a stable application state.
- Record the exact URL, redirect target, timestamp, browser version, and capture options.
- Compare with a defined pixel-difference threshold rather than assuming every antialiasing change is a defect.
Or skip the browser setup
ScreenshotNeo is a website screenshot API and MCP server for developers. It accepts one GET request and can return PNG, JPEG, WebP, or PDF. Before capture, it accepts cookie and consent banners 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.

Troubleshooting batch jobs
A file is missing
Check the manifest or failure CSV instead of treating the job as successful. Confirm DNS, TLS, redirects, robots or access controls, and timeout settings; retry only transient failures.
The screenshot is blank or incomplete
Wait for a specific content selector, scroll or trigger lazy loading, and increase the navigation timeout. Check that the page did not require a login or block the automation browser.
Every image has the wrong dimensions
Distinguish viewport capture from full-page capture and verify viewport and device-scale settings. Element screenshots intentionally use the element’s bounding box.

Files overwrite one another
Use an index-plus-hostname naming scheme, atomic writes, and a no-clobber option where available. Preserve the input URL in the manifest.
Comparisons fail on another machine
Run the same browser, OS/container, fonts, viewport, and timing. Environment differences are a rendering issue, not necessarily a website change.
The batch is too slow or unstable
Measure a pilot, reuse a browser, cap concurrency, and respect target-site rate limits. Increase parallelism gradually while watching memory and error rates.

Frequently Asked Questions
Can I capture authenticated pages in a batch?
Yes. Playwright can load saved storage state, cookies, or authorization headers; hosted services must document equivalent support. Keep credentials out of URL lists and logs.

Should I use full-page screenshots for every URL?
Only when the complete document is needed. Viewport captures are smaller and more comparable; full-page images can be extremely tall and affected by lazy loading.
Are hosted batch limits permanent?
No. Limits and plan requirements are provider terms that can change, so verify the current documentation immediately before automation.
Can batch screenshots be pixel-identical across computers?
Not reliably. Keep the rendering environment, browser, fonts, viewport, and timing consistent for meaningful comparisons.
