See the pdf section on our website for more information.

Install

Using npm:

npm install @browserless/pdf --save

About

This package provides PDF generation from web pages with sensible defaults and smart content detection. It wraps Puppeteer's page.pdf() with optimized settings and a retry mechanism to ensure the page is fully rendered before generating the PDF.

What this package does

The @browserless/pdf package allows you to:

• Generate PDFs from any URL with production-ready defaults
• Wait until the page is ready before printing, including blank-screen checks
• Customize margins with a simple string or per-side configuration
• Scale content to fit pages optimally
• Use all Puppeteer PDF options for advanced customization

Usage

const createPdf = require('@browserless/pdf')
const createGoto = require('@browserless/goto')

const goto = createGoto({ timeout: 30000 })
const pdf = createPdf({ goto })

// With browserless
const browserless = await browser.createContext()
const pdfBuffer = await browserless.pdf('https://example.com')

// Or directly with a page
const page = await browser.newPage()
const pdfFn = pdf(page)
const pdfBuffer = await pdfFn('https://example.com')

Default settings

The package applies these optimized defaults:

Options

All Puppeteer page.pdf() options are supported.

Margin configuration

Set margins as a single value (applied to all sides) or per-side:

// Single value for all sides
await browserless.pdf(url, { margin: '1cm' })

// Per-side configuration
await browserless.pdf(url, {
  margin: {
    top: '2cm',
    right: '1cm',
    bottom: '2cm',
    left: '1cm'
  }
})

Supported units: px, in, cm, mm

Smart content detection

When waitUntil: 'auto' (the default), the package:

1. Navigates to the page
2. Waits for paint/readiness signals (waitForReady + isPageReady)
3. Hydrates overflow content when ready (prepareFullDocument)
4. Generates the PDF

This ensures dynamic content (JavaScript-rendered pages) is fully loaded before PDF generation.

// Use auto detection (default)
await browserless.pdf(url, { waitUntil: 'auto' })

// Or use standard Puppeteer wait conditions
await browserless.pdf(url, { waitUntil: 'networkidle0' })
await browserless.pdf(url, { waitUntil: 'domcontentloaded' })

Examples

Basic PDF generation

const pdfBuffer = await browserless.pdf('https://example.com')
await fs.writeFile('output.pdf', pdfBuffer)

A4 format with custom margins

const pdfBuffer = await browserless.pdf('https://example.com', {
  format: 'A4',
  margin: '2cm',
  scale: 0.8
})

Landscape with header/footer

const pdfBuffer = await browserless.pdf('https://example.com', {
  landscape: true,
  displayHeaderFooter: true,
  headerTemplate: '<div style="font-size:10px; text-align:center; width:100%;">Header</div>',
  footerTemplate: '<div style="font-size:10px; text-align:center; width:100%;"><span class="pageNumber"></span>/<span class="totalPages"></span></div>'
})

Print specific pages

const pdfBuffer = await browserless.pdf('https://example.com', {
  pageRanges: '1-3, 5'
})
