n8n-nodes-pdf-actions

This n8n community node converts images to PDF documents and merges existing PDF files.

Actions

• Multiple Images to Multiple PDFs: creates one PDF for every incoming n8n item. Images on the same item become pages in that item's PDF.
• Multiple Images to One PDF: merges every incoming image into one PDF. This is the default action.
• Multiple PDFs to One PDF: merges every page from every incoming PDF into one document.
• One PDF to Multiple PDFs: creates one single-page PDF for every source page.
• One PDF to Multiple Images: renders every source page as PNG or JPEG.

Input items and binary properties are processed in the order received from n8n.
Multiple outputs use zero-based numbered filenames such as document_0.pdf, document_1.pdf, or page_0.png.
Their n8n binary field names are numbered in the same way, for example data_0, data_1, and data_2.

Installation

Install n8n-nodes-pdf-actions from Settings > Community Nodes in your self-hosted n8n instance.

Configuration

• Action: operation performed by the node.
• Output Binary Field: binary property receiving the generated PDF. The default is data.
• Output File Name: output filename or base name for numbered multi-file outputs.
• Image Format: PNG or JPEG for PDF-to-image conversion.
• Render Scale: controls the dimensions and sharpness of rendered images. The default is 1.
• JPEG Quality: controls JPEG compression quality.
• Keep Source Files: preserves the source images or PDFs alongside the generated PDF.

Examples

With five input items containing one image each:

• Multiple Images to Multiple PDFs returns five output items containing one PDF each.
• Multiple Images to One PDF returns one output item containing a five-page PDF.

With two PDFs containing two and three pages:

• Multiple PDFs to One PDF returns one five-page PDF.

With one three-page PDF:

• One PDF to Multiple PDFs returns output_0.pdf, output_1.pdf, and output_2.pdf.
• One PDF to Multiple Images returns three numbered PNG or JPEG files.

Supported files

Image conversion supports JPEG and PNG through PDFKit. PDF merging uses PDF-Lib. Invalid, encrypted, or unsupported files return a node execution error.

Compatibility

This package uses the current @n8n/node-cli community-node structure and targets modern n8n 2.x installations running Node.js 22.13 or newer.

Development

npm install
npm run lint
npm test
npm run dev

Releasing

After approved pull requests are merged into main, run one non-interactive command:

npm run release:patch
npm run release:minor
npm run release:major

The command runs validation, updates the changelog and version, commits, tags, pushes, and creates the GitHub release. The pushed tag then publishes the package to npm through GitHub Actions and npm Trusted Publishing.
