Documentation

n8n-nodes-pdf4

This is an n8n community node that lets you generate PDFs from HTML templates using PDF4.dev.

PDF4.dev is a developer-first PDF generation API. Create HTML templates with Handlebars variables, preview them live, and render PDFs via REST. Think Resend, but for PDFs.

Installation

Follow the installation guide in the n8n community nodes documentation.

Name: n8n-nodes-pdf4

On self-hosted n8n: Settings → Community Nodes → Install → paste the package name.

Operations

PDF

  • Render From Template — generate a PDF from a saved template with variable data. Works by ID (tmpl_...) or by slug.
  • Render From HTML — generate a PDF from raw HTML without creating a template first. Handlebars variables supported.

Both operations return the PDF either as a binary property (ready to attach, email, or upload downstream) or as a base64 string.

Template

  • List — list all templates in your PDF4.dev account.
  • Get — fetch a single template by ID or slug.

Format overrides

Every PDF operation accepts optional format overrides (preset, custom width/height) that override the template's default format at render time.

Credentials

  1. Sign up at pdf4.dev (free tier available)
  2. Go to Dashboard → Settings → API Keys
  3. Create a key (starts with p4_live_)
  4. In n8n, create a new PDF4.dev API credential and paste the key

The Base URL field only needs to be changed for self-hosted PDF4.dev instances. Leave it as https://pdf4.dev for the hosted service.

Compatibility

  • n8n v1.0 or later
  • Node.js 20.15+

Tested against PDF4.dev API v1.

Usage

Invoice from Airtable record

  2. PDF4.dev — Render From Template
    • Template ID: invoice
    • Data: {{ { customer: $json.customer, total: $json.total, items: $json.items } }}
  3. Gmail — send email with the PDF as attachment (use the binary property from step 2)

Certificate from form submission

  1. Typeform Trigger — on form submission
  2. PDF4.dev — Render From Template
    • Template ID: certificate
    • Data: {{ { name: $json.name, course: $json.course, date: $now.toISO() } }}

Raw HTML quick render

Use Render From HTML when you want to ship a one-off PDF without creating a template in the dashboard. Write your HTML inline (<h1>Hello {{name}}</h1>) and pass a JSON data object.
