react-pdf vs Puppeteer vs pdf-lib 2026: Which PDF Library Should You Use in Node & React?
A practical 2026 comparison of the three ways JavaScript developers generate PDFs — @react-pdf/renderer (design the document as React components with its own layout engine, no browser), Puppeteer (render an HTML/CSS page in headless Chrome and print it to PDF for pixel-perfect fidelity), and pdf-lib (a dependency-free library that draws, fills, merges, and edits PDF bytes directly). Fidelity, bundle size, serverless deployment, fonts, form filling, and which one to build your invoice, report, ticket, or contract feature on.
