Category: File Conversion Type: Output Node Overview: The HTML to PDF Node converts HTML content into a downloadable PDF file. It allows you to design and format professional-looking documents such as reports, invoices, articles, or certificates using HTML and CSS, and then automatically generate a PDF file.

​
Description

The HTML to PDF Node is used to transform structured HTML content into a PDF document. You can either manually write your HTML using the built-in HTML editor or let the AI automatically generate a template for you. Once executed, the node returns a file URL to the generated PDF, which can be downloaded or used in subsequent workflow steps such as “Send Mail” or “Upload File”.

​
Input Parameters

The node accepts the following inputs:
  • HTML Template / HTML Content: The complete HTML structure you want to convert. This includes <html>, <head>, and <body> tags along with embedded CSS for styling.
  • PDF Size: The paper size for the PDF document (e.g., A4, Letter). The default and most commonly used is A4.
  • AI Template Description (Optional): A natural language prompt that describes the kind of HTML template you want the AI to create. You can describe layout, colors, and content ideas, and the system will generate a ready-to-edit HTML structure.

​
Output Parameters

After successful execution, the node returns:
  • File URL: A secure URL where the generated PDF file is stored and can be accessed or downloaded.
  • File ID: A unique identifier for the generated PDF file within the system.
  • PDF Size: The paper size used for generating the PDF.
  • Generated Timestamp: The exact date and time when the PDF was created.

​
Output Type

The node outputs a file object, which includes both metadata and a downloadable link to the generated PDF file. This file can be referenced or passed into other nodes such as email or storage nodes.

​

How to Use in a No-Code Workflow

  1. Add the “HTML to PDF” node to your workflow.
  2. In Node Settings, write or paste your HTML code in the editor.
    • You can use text, images, CSS styling, and variables.
  3. Choose the PDF Size (e.g., A4 or Letter).
  4. Optionally, describe the desired layout and click “Generate Template” to let AI design the HTML automatically.
  5. Click Save Changes.
  6. Connect the output of this node to a node like Send Mail or Return Response to share or view the PDF.

​
Best Practices

  • Keep your HTML simple and properly structured to ensure accurate rendering.
  • Use inline CSS or internal <style> blocks for consistent formatting.
  • Avoid external image URLs unless they are publicly accessible.
  • Always preview your HTML using the built-in editor before generating the PDF.
  • Use clear headings, spacing, and color contrast for readability.

​
Example Workflow Integration

A typical use case for this node might be:
  1. Fetch Data from your database.
  2. Generate HTML Template dynamically using the data.
  3. Convert HTML to PDF using this node.
  4. Send Mail with the generated PDF attached.
This allows you to automate PDF report generation and distribution without writing code.

​
Common Errors

  • Invalid HTML: Unclosed tags or malformed CSS can cause PDF generation to fail.
  • Unsupported Fonts or Images: External resources might not load if hosted privately.
  • Large HTML Content: Very long HTML pages may take extra processing time or fail to render completely.
