Puppeteer and Playwright both support this workflow. The resulting PDF can be written directly to disk or returned as bytes from an API.
Use Puppeteer to generate a PDF
Install Puppeteer in a TypeScript project:
npm install puppeteer
npm install -D typescript tsx @types/nodeCreate convert.ts:
import puppeteer from 'puppeteer';
async function webPageToPdf(url: string, outputPath: string) {
const browser = await puppeteer.launch();
try {
const page = await browser.newPage();
await page.goto(url, {
waitUntil: 'networkidle2',
timeout: 90_000
});
await page.pdf({
path: outputPath,
format: 'A4',
printBackground: true
});
} finally {
await browser.close();
}
}
webPageToPdf('https://example.com', 'example.pdf')
.catch((error) => {
console.error(error);
process.exitCode = 1;
});Run it with npx tsx convert.ts. Puppeteer downloads a compatible browser during installation in the usual setup. In a deployment image, make sure the browser binary and its system dependencies are available.
Return PDF bytes instead of creating a file
Omit path and retain the returned value. Puppeteer returns PDF data that can be written with Node’s file APIs or sent as an HTTP response:
import puppeteer from 'puppeteer';
export async function pdfBytes(url: string): Promise<Uint8Array> {
const browser = await puppeteer.launch();
try {
const page = await browser.newPage();
await page.goto(url, { waitUntil: 'networkidle2', timeout: 90_000 });
return await page.pdf({ format: 'A4', printBackground: true });
} finally {
await browser.close();
}
}For an Express-style endpoint, set Content-Type: application/pdf, optionally set Content-Disposition, and send the returned bytes. Keep browser launch and page cleanup inside a try/finally so timeouts do not leave Chromium processes running.

Wait for the page you actually need
networkidle2 is a useful navigation example, not a universal definition of “finished.” Analytics, websockets, polling, advertisements and lazy components can keep a page active or can render after navigation settles.
Wait for a selector
await page.goto(url, { waitUntil: 'domcontentloaded' });
await page.waitForSelector('#article-content', { timeout: 30_000 });
await page.pdf({ path: 'article.pdf', format: 'A4' });Wait for a known application state
await page.goto(url, { waitUntil: 'domcontentloaded' });
await page.waitForFunction(() => {
return document.querySelector('[data-render-state="ready"]') !== null;
}, { timeout: 30_000 });Use a short fixed delay only when the page has no better readiness signal. A delay alone makes output slower and still may miss content on a busy connection.
Load lazy content before printing
For pages that load images only while scrolling, scroll through the document before calling page.pdf():
await page.evaluate(async () => {
await new Promise<void>((resolve) => {
let y = 0;
const step = 600;
const timer = setInterval(() => {
window.scrollBy(0, step);
y += step;
if (y >= document.body.scrollHeight) {
clearInterval(timer);
window.scrollTo(0, 0);
resolve();
}
}, 100);
});
});Control print layout with CSS and PDF options
Both Puppeteer and Playwright use print CSS media by default. Add print-specific rules to the page or inject them from TypeScript:
await page.addStyleTag({ content: `
@page { size: A4; margin: 18mm 14mm; }
nav, .cookie-banner, .chat-widget { display: none !important; }
h1, h2, h3 { break-after: avoid; }
table, img, pre { break-inside: avoid; }
-webkit-print-color-adjust: exact;
print-color-adjust: exact;
` });Important options include:
- format: a standard paper size such as
A4orLetter. - width and height: explicit dimensions when a standard format is unsuitable.
- landscape: use
truefor wide tables or diagrams. - margin: top, right, bottom and left values.
- printBackground: set
truewhen colored sections or background images matter. - pageRanges: print selected pages, for example
1-3. - scale: adjust content size when it does not fit the selected paper.
- preferCSSPageSize: let an
@pagerule determine dimensions where supported. - displayHeaderFooter,
headerTemplateandfooterTemplate: add repeating PDF headers and footers where supported by your installed version.
If you want the screen design rather than print design, emulate screen media before generating the PDF:

await page.emulateMediaType('screen');
await page.pdf({ path: 'screen-style.pdf', printBackground: true });Print rendering can alter colors. The -webkit-print-color-adjust: exact declaration requests the page’s colors, but the final appearance still depends on browser and PDF viewer behavior.
Make fonts, authentication and navigation predictable
Fonts
Puppeteer’s PDF method waits for fonts by default in current versions. If a custom font is critical, explicitly wait for it:
await page.evaluate(async () => {
await document.fonts.ready;
});A background page or a font blocked by credentials, CSP or network policy can still fall back to another font. Verify that the font request succeeds inside the browser.
Recommended Free Tools
Authenticated pages
Set cookies, HTTP headers or login state before navigation. Never place secrets in a URL that may be logged:
await page.setExtraHTTPHeaders({ Authorization: `Bearer ${process.env.API_TOKEN}` });
await page.goto('https://example.com/private-report', {
waitUntil: 'domcontentloaded',
timeout: 90_000
});For a session cookie, use page.setCookie() with the correct domain, path, secure and expiry properties. Treat the generated PDF as sensitive data and delete temporary files when they are no longer needed.

Navigation failures
Use an explicit timeout and inspect the navigation result. A page can return an HTTP error while still producing HTML, so decide whether your application should reject non-success status codes.
const response = await page.goto(url, {
waitUntil: 'domcontentloaded',
timeout: 90_000
});
if (!response || !response.ok()) {
throw new Error(`Navigation failed: ${response?.status() ?? 'no response'}`);
}Playwright alternative
If your project already uses Playwright, its page-level PDF API follows the same model and returns PDF data. A minimal implementation is:
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 problemsimport { chromium } from 'playwright';
const browser = await chromium.launch();
try {
const page = await browser.newPage();
await page.goto('https://example.com', {
waitUntil: 'networkidle',
timeout: 90_000
});
const pdf = await page.pdf({
format: 'A4',
printBackground: true
});
await Bun.write('example.pdf', pdf);
} finally {
await browser.close();
}With Node.js, use writeFile('example.pdf', pdf) from node:fs/promises instead of Bun.write. Choose the library already used by your tests or browser automation; the documented PDF behavior is similar, but option names and defaults depend on the installed version.
Common errors and fixes
| Symptom | Likely cause | Fix |
|---|---|---|
| Blank or nearly empty PDF | JavaScript content was not ready, or the wrong frame was printed. | Wait for a page-specific selector or ready flag; confirm the URL and frame. |
| Images missing | Lazy loading, blocked requests or cross-origin failures. | Scroll to trigger lazy images, wait for image completion, and inspect browser console/request errors. |
| Wrong colors or no backgrounds | Print media rules or disabled background printing. | Set printBackground: true, add print color adjustment, or emulate screen media. |
| Content clipped | Margins, scale, fixed widths or an unsuitable paper orientation. | Use CSS @page, landscape mode, a smaller scale or responsive print rules. |
| Timeout during navigation | Long polling, slow assets, bot checks or an unreachable host. | Use a readiness condition instead of network idle, increase the timeout only when justified, and log the failing URL. |
| Browser will not launch in production | Missing Chromium executable or Linux libraries. | Install the browser and OS dependencies in the image, or configure the executable path explicitly. |
| Fonts differ from the browser preview | Font requests failed or completed after capture. | Check font responses, wait for document.fonts.ready, and ensure the same fonts are available in deployment. |
Performance, reliability and cost considerations
Launching a new browser for every request is simple but expensive at scale. A worker can reuse one browser and create isolated pages, while still closing each page in a finally block. Limit concurrency so memory use does not grow without bound. Set navigation and PDF timeouts, record URL and status diagnostics, and retry only transient failures; repeated retries will not fix a deterministic layout or authentication error.
Cache PDFs when the source URL and relevant inputs have not changed. For untrusted URLs, restrict outbound network access and prevent access to internal services. Validate allowed schemes, enforce maximum document size and consider request-level cancellation. The PDF contains whatever the browser can access, including private data.

FAQ
Can TypeScript convert HTML strings rather than URLs?
Yes. Open a page, call page.setContent(html), wait for required assets or selectors, and then call page.pdf(). External images and fonts must still be reachable by the browser.
