Seamless PDF Document Consolidation
detail.loadingPreview
Efficiently combine multiple PDF documents into a single, unified file with this n8n workflow. It automates the process of fetching PDFs from various sources, merging them, and saving the consolidated document locally.
About This Workflow
This n8n workflow provides a robust solution for automating the merging of PDF documents. It starts by fetching PDF files from specified web URLs, but can easily be extended to include files from cloud storage, email attachments, or local directories. The workflow then leverages a powerful custom PDF toolkit node to seamlessly combine these individual PDFs into one comprehensive document. Finally, the merged PDF is saved to disk, making it ready for further processing, archival, or distribution. This automation eliminates manual effort, reduces errors, and standardizes your document management processes.
Key Features
- Automated PDF Retrieval: Automatically download PDF files from any accessible URL or integrated services.
- Robust PDF Merging: Utilize a custom PDF toolkit node for reliable and accurate document consolidation.
- Local File Storage: Save the resulting merged PDF directly to your n8n environment's disk for easy access or subsequent actions.
- Extensible Design: Easily adapt the workflow to fetch PDFs from diverse sources like Google Drive, Dropbox, email, or internal systems.
- Error Reduction: Eliminate manual copy-pasting and potential errors associated with combining documents.
How To Use
- Start Workflow: Click 'Test workflow' on the 'When clicking ‘Test workflow’' node to manually initiate the process. You can later replace this with a scheduled trigger or webhook for automation.
- Configure HTTP Request Nodes: For 'HTTP Request' and 'HTTP Request2' (and any additional HTTP Request nodes you add), update the
URLparameter with the direct links to the PDF files you wish to merge. Ensure the URLs are publicly accessible or require appropriate authentication (which can be added in theOptionsparameter). - Add More PDF Sources (Optional): If you have more than two PDFs to merge, add additional 'HTTP Request' nodes (or other file-fetching nodes like Google Drive, S3, etc.) and connect their outputs to the 'Merge' node. Make sure the 'Merge' node has enough input branches configured.
- Review Merge PDF Node: The 'Merge PDF1' node, using the
@custom-js/n8n-nodes-pdf-toolkit.mergePdfscustom node, will automatically take all incoming PDF binaries and combine them. No specific configuration is typically needed here unless you have advanced requirements for the custom node. - Set Output File Name: In the 'Read/Write Files from Disk' node (the one named 'Read/Write Files from Disk'), specify your desired
File Namefor the merged PDF, e.g.,merged_document.pdf. - Verify Output (Optional): The last 'Read/Write Files from Disk4' node is set to read
test.pdf. This can be used to verify the output or pass the merged PDF to another node (e.g., upload to cloud storage, send via email).
