Both Puppeteer and Playwright can drive a headless browser to generate PDFs from HTML. If you're choosing between them for document generation—or wondering whether to run them yourself at all—here's a concise comparison and when an API might be a better fit.
Puppeteer: Chrome-first, simple PDF API
Puppeteer is the Node.js library maintained by the Chrome team. It targets Chromium/Chrome and exposes a straightforward page.pdf() method. You control the page (navigate, set content, wait for network), then call page.pdf({ format: 'A4', printBackground: true, ... }) and get a buffer. It's well documented and widely used for HTML-to-PDF.
Pros: Simple API, excellent for PDF and screenshots; Chrome-only keeps the surface small. Cons: You run and scale Chrome yourself; concurrent jobs can exhaust memory; you handle updates and security patches.
Playwright: Multi-browser, modern API
Playwright (Microsoft) supports Chromium, Firefox, and WebKit. For PDF, you use page.pdf(...) in a similar way. The API is a bit richer (e.g. auto-waiting, multiple contexts), and many teams prefer it for E2E tests. For PDF-only workloads, the main advantage is flexibility (e.g. testing in WebKit) and a single toolkit for tests and document generation.
Pros: One library for tests and PDFs; multi-browser if you need it. Cons: Same operational burden as Puppeteer: you host the browsers, manage concurrency, and maintain the stack.
Head-to-head for PDF
- Output quality: Both use the browser's print path; for Chromium the result is effectively the same.
- Performance: Similar per-document; scaling depends on how many browser instances you run and how you queue work.
- Maintenance: Both require installing and updating browser binaries; Playwright's multi-browser support can mean more surface to maintain if you use it.
When to use an API instead
Running Puppeteer or Playwright yourself makes sense when you need offline generation, strict data residency, or already have a dedicated team and infrastructure. For many apps, a PDF API (like Doppio) is simpler:
- No Chrome/Playwright installs in your app or CI
- No queue or concurrency logic; the API scales for you
- Predictable cost and no browser security patching
- Same kind of control: pass URL or HTML, get PDF or screenshot
Doppio's API is designed to feel familiar if you've used Puppeteer: you send a JSON payload with page.goto, page.pdf, or page.screenshot options and get back a document URL or binary. So you can "switch" from self-hosted Puppeteer/Playwright to an API without rethinking your document design.
Summary
For PDF generation specifically, Puppeteer and Playwright are comparable in output and effort; choose by ecosystem and whether you need multi-browser. If you'd rather not run browsers at all, use a PDF API and keep your HTML/CSS—you get the same quality without the ops. For a hands-on Puppeteer example, see How to generate PDFs with Node.js and Puppeteer; for the API approach, check the Doppio documentation.
