PDF Generation Options for Web Apps Part of our complete guide to this topic — see the full series. Choosing a PDF generation approach for a web application involves tradeoffs between CSS fidelity, server infrastructure, client-side options, throughput, and cost. This guide compares the main approaches with enough detail to make an informed choice. --- What about The Main Approaches? | Approach | Where it Runs | CSS Support | Complexity | |---|---|---|---| | Browser print-to-PDF | Client browser | Full (Chrome/Firefox) | Low | | Puppeteer (headless Chrome) | Node.js server | Full CSS3 | Medium | | Playwright | Node.js server | Full CSS3 | Medium | | wkhtmltopdf | Any server | CSS 2.1 + partial CSS3 | Low | | WeasyPrint | Python server | Good CSS3 | Low–Medium | | jsPDF + html2canvas |…
Frequently Asked Questions
What are the best ways to generate PDFs in web apps?
For HTML-based documents: Puppeteer (headless Chrome) gives the highest fidelity. For templated PDFs: pdf-lib (JavaScript) or ReportLab (Python) for programmatic control. For client-side generation without a server: jsPDF with html2canvas. For academic/typeset documents: LaTeX via pdflatex.
What is the difference between Puppeteer and wkhtmltopdf?
Puppeteer uses a current version of Chrome — it supports CSS3, web fonts, and modern JavaScript. wkhtmltopdf uses a frozen Qt WebKit from around 2015 — it lacks CSS Grid, flexbox in some cases, and modern CSS features. Puppeteer is the clear technical winner; wkhtmltopdf is still used in legacy systems.
How do I generate PDFs at scale?
Use a browser pool (multiple Puppeteer instances running concurrently) or a dedicated PDF microservice like Gotenberg. For very high volume, serverless functions (AWS Lambda with headless Chrome layers) auto-scale. Cache identical PDFs by input hash to avoid re-generating the same document repeatedly.
What is React-PDF?
React-PDF (from @react-pdf/renderer) is a React renderer that outputs PDF files instead of DOM elements. You write JSX using PDF-specific components (Document, Page, Text, View, Image) and call pdf().toBuffer() or pdf().toBlob() to get the PDF. It's suitable for data-driven documents where you want a React component tree to produce PDFs directly.
How do I generate PDFs without a server?
Use jsPDF (capture DOM with html2canvas then add to PDF), or @react-pdf/renderer to generate PDFs entirely in the browser. For best quality, Puppeteer requires a server. Client-side generation is sufficient for simple layouts; complex multi-page documents with precise pagination are better handled server-side.
