Convert HTML to PDF & Compress Files with CustomJS API

This n8n workflow transforms HTML content into PDF files and compresses them using the CustomJS PDF Toolkit community nodes. It starts with a Manual Trigger, processes HTML data to generate PDFs, fetches PDFs from URLs if needed (especially for files over 6MB), and applies compression to reduce file sizes significantly. A Code node manages URL-based PDF handling, ensuring seamless integration.

Key benefits include substantial time savings in document workflows, reduced storage costs through compression, and high-quality output without quality loss. It's perfect for businesses dealing with reports, invoices, or web content needing PDF archiving. Requires a self-hosted n8n setup and a free CustomJS API key for compression features.

Use cases span knowledge retrieval in BI, automating newsletter-to-PDF conversion, compressing scanned documents, or integrating into larger pipelines via webhooks. Easily customizable: replace Manual Trigger with webhooks for API-driven execution and return binary PDFs directly.
