PDFKit is a Node.js library for drawing PDFs programmatically. PDF4.dev renders HTML/CSS templates with a visual editor and REST API.

PDFKit requires you to draw every element with coordinates. HTML templates let you use the skills web developers already have.
// PDFKit: draw every element manually
const PDFDocument = require('pdfkit');
const doc = new PDFDocument();
doc.fontSize(20).text('Invoice #INV-001', 50, 50);
doc.fontSize(12).text('Acme Corp', 50, 80);
doc.moveTo(50, 110).lineTo(550, 110).stroke();
// Table header
doc.fontSize(10).font('Helvetica-Bold');
doc.text('Item', 50, 130);
doc.text('Qty', 300, 130);
doc.text('Price', 400, 130);
doc.text('Total', 480, 130);
// Table row (repeat for each row...)
doc.font('Helvetica');
doc.text('Web Development', 50, 150);
doc.text('40', 300, 150);
doc.text('$150.00', 400, 150);
doc.text('$6,000.00', 480, 150);
// Footer
doc.text('Total: $6,000.00', 400, 200);
doc.end();
// 200-400 lines for a real invoice...<!-- PDF4.dev: standard HTML template -->
<h1>Invoice #{{invoice_number}}</h1>
<p>{{company_name}}</p>

<p><strong>Total: {{grand_total}}</strong></p>A real invoice with PDFKit typically needs 200-400 lines of drawing code. The same layout in HTML takes a standard template with CSS styling.
PDFKit is a solid choice for specific use cases where its low-level API is an advantage, not a limitation:
But if your use case is “I have data and I need documents that look like web pages” (invoices, reports, certificates, contracts), HTML templates are faster to build, easier to maintain, and accessible to non-developers.
Design your template visually, inject data with Handlebars, and generate PDFs with a single API call.
