PDF Merge & Split — OpenClaw Plugin

Merge and split PDF documents using the PDFAPIHub API. This OpenClaw plugin gives your AI agent the ability to combine multiple PDFs, extract specific pages, split documents into parts, and compress the results.

What It Does

Combine multiple PDF files into a single document, split large PDFs into smaller parts, and compress the output — perfect for invoice bundling, report assembly, chapter extraction, and document management.

• Split by Pages — Extract specific pages or ranges (e.g. 1-3,5,8-10)
• Split Each Page — One PDF per page for batch processing
• Split into Chunks — Divide into N roughly equal parts
• Open-Ended Ranges — 5- means page 5 to the end
• PDF Compression — Reduce file size with low/medium/high/max compression
