Use @react-pdf/renderer for invoices, reports, and other documents designed specifically for PDF. Use Chromium with Puppeteer—or the browser’s print dialog—to preserve an existing page’s HTML and CSS. The right choice depends on how closely the output must match the web page, how much control you need over pagination, and whether export runs interactively or on a server.
Choose a conversion method
| Method | Best for | What it renders | Main trade-off |
|---|---|---|---|
@react-pdf/renderer |
Invoices, reports, certificates, forms | A PDF-specific React component tree | You design the document with PDF primitives rather than reusing arbitrary DOM and CSS. |
| Puppeteer and Chromium | Server-generated printouts of an existing React route | The rendered HTML page, styled for print by default | Requires a browser runtime and reliable handling of page readiness and CSS pagination. |
| Browser print dialog | A user-triggered export with minimal infrastructure | The page as handled by the user’s browser and print settings | Less predictable for unattended or batch output. |
These approaches solve different problems. A React component does not automatically become a PDF: either build a document using PDF-oriented components, or render the normal web page in a browser and print it.
Use @react-pdf/renderer for a PDF-native document
The official v4 quick start installs the package with npm install @react-pdf/renderer --save. It provides components such as Document, Page, View, and Text, styled with JavaScript style objects and a flexbox-like layout model. It is not a renderer for ordinary DOM elements or arbitrary web CSS; create a separate component tree for the PDF.
Install and create a document
npm install @react-pdf/renderer --saveimport { Document, Page, Text, View, StyleSheet } from '@react-pdf/renderer';
const styles = StyleSheet.create({
page: { padding: 36, fontSize: 12 },
title: { fontSize: 20, marginBottom: 16 },
row: { marginBottom: 8 },
});
export default function Invoice() {
return (
<Document>
<Page size="A4" style={styles.page}>
<Text style={styles.title}>Invoice</Text>
<View style={styles.row}>
<Text>Invoice number: INV-1042</Text>
</View>
<View style={styles.row}>
<Text>Amount due: $240.00</Text>
</View>
</Page>
</Document>
);
}In a client-side React app, render the document with the library’s PDFViewer to preview it, or use the browser download workflow provided by the library. On a Node server, the library supports ReactPDF.render() and ReactPDF.renderToStream(). Consult the react-pdf documentation for the current API and the correct browser or server entry point for your app.

Choose this method when you control the content and want explicit PDF-oriented layout. It is a poor fit if the requirement is to capture a complex existing page unchanged: translating the page into Document, Page, View, and Text is a separate implementation.
Print an existing React page with Puppeteer
Puppeteer drives Chromium and calls page.pdf() to create a PDF. Its official API generates the PDF using the print CSS media type by default; call page.emulateMediaType('screen') first if you specifically want screen styles. page.pdf() returns a Promise<Uint8Array>. The guide’s basic sequence is to launch a browser, open a page, navigate, generate a PDF, and close the browser.
Runnable Node.js example
This example assumes the React app is already running at the URL you provide. Install Puppeteer, save the script as an ES module such as print-page.mjs, and replace the example URL with a route that displays the page to export.
npm install puppeteerimport puppeteer from 'puppeteer';
const url = process.env.REACT_PAGE_URL ?? 'http://localhost:3000/invoice/1042';
const browser = await puppeteer.launch();
try {
const page = await browser.newPage();
await page.goto(url, { waitUntil: 'networkidle2' });
// Optional: use screen CSS instead of the default print CSS.
// await page.emulateMediaType('screen');
await page.pdf({
path: 'output.pdf',
format: 'A4',
printBackground: true,
margin: { top: '12mm', right: '12mm', bottom: '12mm', left: '12mm' },
});
} finally {
await browser.close();
}Run it with REACT_PAGE_URL=http://localhost:3000/invoice/1042 node print-page.mjs. The navigation wait is not a substitute for application-specific readiness: a route may still be fetching data, loading images, or rendering after navigation completes. Add a selector wait or an app-provided ready signal when needed, and confirm the page’s content is complete before creating the PDF. Puppeteer’s Page.pdf API states that it waits for fonts to load by default.
Prepare the page for printing
Use a dedicated print route or print-specific CSS so the exported document is intentional rather than a raw screenshot of the interactive app. For example:

@page {
size: A4;
margin: 12mm;
}
@media print {
.site-nav,
.export-button,
.interactive-controls {
display: none !important;
}
.report-section {
break-inside: avoid;
}
a {
color: inherit;
text-decoration: none;
}
}Set page size and margins explicitly, decide whether backgrounds and colors matter, hide navigation or controls, and use page-break rules for sections, tables, and headings. Print CSS is subject to browser pagination behavior, so inspect the resulting pages rather than assuming a web layout will divide cleanly.
Let a user save a React page as PDF
For a user-triggered export, expose a print-friendly view and call window.print() from a button or other user action:
function PrintButton() {
return (
<button type="button" onClick={() => window.print()}>
Print or save as PDF
</button>
);
}The browser opens its print interface; the user chooses the available Save as PDF destination. Define @media print rules for hidden controls, margins, and page breaks. This avoids adding a PDF-generation library, but output can vary with browser behavior and the user’s print settings. It is not the best option for unattended batch generation.
Wait for the right content before capture
PDF generation can faithfully print an incomplete page if the application has not finished loading. Before calling page.pdf(), account for data, images, and fonts. Puppeteer waits for fonts by default, but your app’s API requests and image rendering still need appropriate readiness handling. A route-specific selector can serve as a simple gate:
await page.goto(url, { waitUntil: 'networkidle2' });
await page.waitForSelector('[data-pdf-ready="true"]');
await page.pdf({ path: 'output.pdf', format: 'A4', printBackground: true });Set data-pdf-ready="true" only after the data and page elements required for the document are present. For highly dynamic routes, a deliberate application readiness condition is more reliable than treating a navigation event as proof that all meaningful content has settled.

Large documents, performance, and reliability
The react-pdf advanced documentation warns that rendering documents with 30 pages or more directly in the browser can occupy the browser’s main thread for a long time, and recommends rendering large documents inside a web worker so the UI remains responsive. This is guidance, not a benchmark or a guarantee about every document. Measure generation time and memory use with representative content.
For large exports or batch work, consider server-side generation, a background job, or a worker-based browser implementation instead of blocking the user’s active page. With Puppeteer, also control the browser/runtime and make page readiness deterministic: the same route should load the same data, fonts, and assets before capture. A worker can keep the UI responsive, but it does not eliminate the need to test resource use or output quality.

Pick the symptom - the matching free tool is one click away.
Check the PDF before shipping it
Inspect multiple pages, including the first and last, and test realistic long content. Check for:
- Text or images clipped at page boundaries, unexpected blank pages, and awkward page breaks.
- Tables split across pages in ways that obscure headers or totals.
- Missing backgrounds, altered colors, or content hidden by print styles.
- Font substitution, missing glyphs, and text that is not selectable as expected.
- Working links, sensible reading order, and appropriate metadata or accessibility characteristics for your chosen renderer.
Generated PDFs are static artifacts. Do not assume that a visually correct preview also guarantees usable links, selectable text, reading order, or accessibility metadata; verify those properties in the actual output.

The PDF is blank or missing route content
Check that the app is reachable from the environment running Chromium and that navigation reaches the intended route. If the page loads data after navigation, wait for a route-specific ready selector before printing. Confirm that the data required for the PDF is available to that session.
Fonts or images are missing
Verify the browser can load the asset URLs and that they are not blocked by authentication, network policy, or an incorrect base path. Wait for application content and image loading before printing. Puppeteer’s PDF API waits for fonts by default, but check that the intended font files actually loaded.
Screen styling appears wrong
page.pdf() uses print media by default. Add @media print styles for the desired output, or call page.emulateMediaType('screen') before generating the PDF if the screen stylesheet is the intended design. Screen styles may still paginate differently when printed.

Content is cut off or pages break badly
Set page format and margins explicitly, review @page rules, and add print-specific break behavior to the sections that need it. Check long tables and images at several content lengths; a layout that works for a short example may fail on a full report.

The browser appears frozen during a large export
For react-pdf documents of 30 pages or more, the project warns that direct browser rendering can occupy the main thread for a long time. Consider a web worker, server-side rendering, or a background job, and test memory and generation time using the real document size.
Implementation checklist
- Decide whether the output is a printout of an existing page or a separately designed PDF document.
- For a printout, create a print route or stylesheet; for a document, build with the PDF renderer’s
DocumentandPagecomponents. - Wait for API data, images, and fonts before generation, using a specific ready condition where needed.
- Set page format, margins, headers or footers, colors, and break rules deliberately.
- Use browser generation for small interactive exports; consider Node, a worker, or background processing for large and batch jobs.
- Inspect the finished PDF for clipping, blank pages, broken tables, fonts, links, text selection, reading order, and accessibility needs.
Frequently Asked Questions
Can I use regular HTML elements directly with @react-pdf/renderer?
No. It uses its own PDF-oriented primitives such as Document, Page, View, and Text; it is not a renderer for arbitrary DOM elements and CSS.
Does Puppeteer use print CSS or screen CSS for PDFs?
Print CSS is used by default. Call page.emulateMediaType(‘screen’) before page.pdf() if you want screen media styles.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesIs browser print suitable for automated batch PDF generation?
It is best suited to user-triggered exports because the browser and user print settings affect the result; unattended work is better handled by a controlled server or worker workflow.
