For converting an existing, modern HTML page to PDF on a server, start with Puppeteer or Playwright, which print a page rendered by a browser. For a browser-only, user-triggered export, consider html2pdf.js, after testing its canvas-based approach against your documents. If you are creating a document from structured data rather than converting an existing page, PDFKit or pdfmake may be a better fit. There is no universal best library: choose based on where rendering should run, how closely the PDF must match the rendered page, and how much control you need over pagination and operations.
Choose the rendering approach before the library
“HTML to PDF” can mean either printing a rendered web page or building a PDF that happens to contain the same information as a web page. Those are different jobs. A browser engine evaluates CSS and JavaScript and lays out the page; a PDF-generation library typically asks your code to define the text, graphics, and layout.
| Approach | Good fit | Tradeoffs to evaluate |
|---|---|---|
| Headless browser: Puppeteer or Playwright | Server-side rendering of existing HTML templates or pages whose output depends on browser CSS and JavaScript. | You must run and operate a browser, decide how print styles and page breaks should behave, and validate output in the target environment. |
| Browser-side conversion: html2pdf.js | A user-triggered export that must run in the visitor’s browser without a server-side browser workflow. | It uses html2canvas and jsPDF; test text quality, links, page breaks, memory, and long or image-heavy pages. Its package documentation notes a canvas-size limitation that can produce blank output for very large documents. |
| Programmatic PDF construction: PDFKit or pdfmake | Invoices, reports, or other documents whose content and layout can be described from structured application data. | These generate PDF content; they do not automatically reproduce arbitrary existing HTML and CSS. Plan to build and maintain the layout in the library’s model. |
Before choosing, answer these questions: Does the export run in a browser or in Node.js? Is an existing page the source of truth, including its runtime-generated content? How exact must fonts, colors, images, links, and page breaks be? Is the PDF better described directly from structured data? The comparison in Nutrient’s JavaScript HTML-to-PDF overview offers editorial context, not a benchmark or official compatibility matrix.
Best starting points for existing HTML
Puppeteer: print a page with Chromium
Puppeteer is a strong starting point when a Node.js service needs a browser to render an existing page and print it. Its official guide documents PDF generation through Page.pdf(); the guide displayed version 25.12.0 when accessed. By default, PDF generation uses print CSS media and waits for fonts to load. Those defaults are useful, but they also mean screen-only styles and assets that arrive late deserve explicit testing. See the Puppeteer PDF generation guide and the Page.pdf() API documentation.

Playwright: a browser-based alternative
Playwright belongs in the same headless-browser category when you want to render a page before printing it. The material available for this comparison does not establish a feature-by-feature ranking of Playwright against Puppeteer, so choose by the browser tooling and deployment approach that suits your project, then test the resulting PDFs. Do not treat a general comparison as proof that one library is faster or more faithful for your page.
html2pdf.js: keep conversion in the browser
html2pdf.js targets client-side export and must run in a browser; its package documentation identifies html2canvas and jsPDF as dependencies. That can suit a simple “Download PDF” action where sending page content to a server is undesirable or impractical. It is not a Node.js page-rendering substitute. Canvas has practical size limits, so validate the longest and most visually complex documents you expect to export. The html2pdf.js package documentation describes that limitation.
When a PDF-generation library is the better choice
PDFKit for documents built from data
PDFKit describes itself as “A JavaScript PDF generation library for Node and the browser.” Its project lists text, vector graphics, embedded fonts, images, tables, annotations, forms, outlines, security, and accessibility features. Choose it when your application can define document structure directly and you value control over PDF content over automatic reproduction of arbitrary HTML. Project details are on the PDFKit website.
Rank #2
Runtime details matter: the PDFKit getting-started guide says Node builds have file-system access and Node streams, while browser builds cannot access the file system and require in-memory registration for file-like paths. It also describes toBlob and toBytes as experimental helpers; do not build a stable workflow around those helpers without checking their status in the version you install.
pdfmake for declarative document definitions
pdfmake is another option when you can express a document as a structured definition rather than needing to print an existing HTML page. This comparison does not establish a current feature matrix or compatibility details for pdfmake, so confirm its documentation for the version and runtime you plan to use. In either case, the key tradeoff is the same: a generated document may be easier to control as data, but you are responsible for recreating the intended layout.
Render and print an HTML page with Puppeteer
This Node.js example opens a URL and writes its rendered page to a PDF. It uses Puppeteer’s print-media default, explicitly waits for the page’s load event and fonts, and then saves the result. Install Puppeteer in your project with npm install puppeteer; use a URL you control or are authorized to capture.
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
try {
const page = await browser.newPage();
await page.goto('https://example.com', { waitUntil: 'load' });
await page.evaluate(() => document.fonts.ready);
await page.pdf({
path: 'page.pdf',
format: 'A4',
printBackground: true,
margin: { top: '12mm', right: '12mm', bottom: '12mm', left: '12mm' }
});
} finally {
await browser.close();
}
})();For a locally generated HTML document, use page.setContent(html, { waitUntil: 'load' }) instead of page.goto(). If the page’s scripts populate content after load, wait for a page-specific condition before printing—for example, a selector that appears only after rendering. A fixed delay can be a fallback, but it is less reliable than waiting for the actual content. Do not assume that network idle alone means a complex page is ready: analytics, polling, or lazy-loaded content can keep requests open or load only after scrolling.
Control media and print appearance
Page.pdf() uses print CSS media. If the PDF should match screen styling instead, emulate screen media before calling it:

1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsawait page.emulateMediaType('screen');
await page.pdf({ path: 'page.pdf', printBackground: true });PDF printing can modify colors by default. Puppeteer’s API documentation points to -webkit-print-color-adjust when exact colors are needed. Apply it deliberately in print CSS and inspect the result; color adjustment is not a substitute for checking contrast and legibility on paper.
Rank #4
@media print {
html {
-webkit-print-color-adjust: exact;
print-color-adjust: exact;
}
.avoid-split {
break-inside: avoid;
}
}Use print-specific styles to hide navigation, simplify backgrounds, set page margins, and control breaks. Check the PDF rather than assuming a screen layout will paginate naturally. Wide tables, fixed-position elements, long code blocks, and headings at the bottom of a page are common cases to review.
Test the details that determine PDF quality
- Pagination: Check page count, clipped content, unwanted blank pages, repeated headers, and whether important blocks split awkwardly. Use print CSS and page-break rules suited to the content.
- Fonts: Confirm that web fonts have loaded before printing and that the deployed environment can fetch or access them. Puppeteer’s guide says PDF generation waits for fonts by default, but page readiness and font availability still need validation.
- Images and lazy content: Verify that every image appears in the PDF. If content only loads after scrolling or interaction, make it render before printing.
- Links and selectable text: Check whether text remains selectable and links behave as expected. Canvas-based conversion can have different text and link characteristics from browser printing, so inspect actual output.
- Colors and backgrounds: Confirm print media styles, background graphics, and color adjustment match the intended result.
- Runtime behavior: Run the export in the same operating environment and browser setup used in production. A local success does not establish that fonts, assets, or browser processes will behave identically elsewhere.
Common problems and fixes
| Symptom | Likely cause | What to try |
|---|---|---|
| Content is missing or still loading | The export began before asynchronous page rendering or assets finished. | Wait for a page-specific selector or application-ready signal; explicitly wait for fonts when appropriate. |
| PDF looks different from the website | Print media is active by default, or print CSS and screen CSS differ. | Decide whether print or screen media is intended; emulate screen media only if that is the desired output, then retest pagination. |
| Backgrounds or colors are absent or changed | Print settings or CSS color adjustment affect printed output. | Set printBackground as needed and review -webkit-print-color-adjust in print CSS. |
| Very long browser-side export is blank | A canvas-size limit may have been reached. | Test a shorter or simpler document, reduce large imagery, or move rendering to a headless-browser workflow if appropriate. |
| PDFKit cannot read a file-like path in a browser | Browser builds do not have Node file-system access. | Register file-like content in memory as described by PDFKit’s getting-started documentation. |
| Output breaks tables, cards, or code awkwardly | Screen layout has no suitable print pagination rules. | Add print styles and break controls, then inspect representative short and long records. |
Operational and cost considerations
A self-hosted headless browser gives you control over the rendering workflow, but your service must launch and manage browser execution and validate resource loading and print behavior. Client-side conversion shifts the work to the visitor’s browser and avoids a server-side rendering step, but page complexity and browser memory become part of the user experience. Programmatic PDF construction avoids reproducing arbitrary browser layout only when the document can be authored from structured content in the first place.
The supplied comparison material contains no verified performance figures, adoption counts, or controlled benchmarks for these libraries. Measure your own representative pages and deployment rather than relying on unsupported speed or quality rankings. If your team prefers a hosted screenshot workflow over setting up a browser, ScreenshotNeo is a separate website screenshot API and MCP server—not an HTML-to-PDF library. Its PDF endpoint and options are documented alongside its API.

If a screenshot is enough for a page capture, ScreenshotNeo returns a screenshot or PDF from one GET request. For a PDF response, use its API’s PDF option as documented; the following example captures a web page as a WebP image:
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpSee the ScreenshotNeo API documentation for PDF output and request options. ScreenshotNeo accepts cookie and consent banners and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; each step can be turned off. Bot checks, blank pages, timeouts, failed loads, and cache hits are not billed, and response headers report the page verdict and billing status. Its MCP server provides screenshot and PDF tools for AI agents. The free plan includes 1,000 screenshots per month without a card; paid plans start at $5 for 3,000 shots. Sign up for the free plan.
Which one should you choose?
- Choose Puppeteer or Playwright when you need a server-side browser to render an existing modern page and print it.
- Choose html2pdf.js when export must happen in the browser and your tested document complexity suits its canvas-based workflow.
- Choose PDFKit or pdfmake when the PDF can be defined from structured data and recreating the layout is acceptable.
- Before shipping, validate fonts, pagination, colors, images, links, runtime behavior, and long-document cases using representative pages.
Frequently Asked Questions
Can Puppeteer generate a PDF from HTML that is not hosted at a URL?
Yes. Set the page content with Puppeteer’s page content API, wait for the document and its assets to render, then call Page.pdf().
Does html2pdf.js run in Node.js?
No. Its package documentation says it must run in a browser.
Are PDFKit and pdfmake HTML-to-PDF converters?
They are PDF-generation approaches for describing document content and layout. They do not automatically reproduce arbitrary HTML and CSS.
