Convert DOCX (from URL) to PDF Using ConvertAPI – Free n8n Workflow

Tired of manually downloading DOCX files and converting them to PDF? Whether you're a freelancer processing client contracts, a small business owner handling invoices, or a developer building document pipelines, this n8n workflow: Convert DOCX (from URL) to PDF using ConvertAPI automation will save you hours every week.

In this step-by-step guide, you'll learn how to set up a fully automated system that takes any publicly accessible DOCX file URL, sends it to ConvertAPI, and delivers a perfectly formatted PDF—all without writing a single line of code. Plus, we're giving you the complete free n8n template for DOCX to PDF conversion so you can deploy it in under 5 minutes.

How This n8n Workflow Works

This automation uses four core n8n nodes working together seamlessly:

• 1.
  Manual Trigger: Starts the workflow when you provide a DOCX URL.
• 2.
  HTTP Request: Fetches the DOCX file from the provided URL.
• 3.
  ConvertAPI Node: Converts the fetched DOCX into PDF format.
• 4.
  Set + Read/Write File: Saves or returns the final PDF for download or further processing.

The entire process takes seconds and requires no manual intervention after setup. It’s ideal for scenarios like converting Google Docs exports, client-submitted reports, or dynamically generated proposals into standardized PDFs.

Configuring the Workflow

Instead of building from scratch, we recommend importing our ready-made template. But if you want to understand the logic, here’s how each node is configured:

1. Manual Trigger Node

This node waits for you to input a DOCX file URL. You’ll use this as the starting point for testing and one-off runs.

2. HTTP Request Node

Configure this node to GET the DOCX file from the URL provided in the trigger. Set the response format to "File" so n8n handles it as binary data.

3. ConvertAPI Node

Connect your ConvertAPI credentials and set the operation to "Convert DOCX to PDF". Map the binary data from the HTTP Request node as the input file.

4. Set & Read/Write File Nodes

Use the Set node to structure the output (e.g., add metadata like filename and timestamp), then use Read/Write File to save the PDF locally or pass it to another service (like email or cloud storage).
