PDF Tools

What it does

PDF Tools brings a full interactive PDF workspace into Claude Desktop. You can view, fill, analyse, and manipulate PDFs already on your computer — no uploads, no third-party cloud. It renders an interactive viewer with search, zoom, and a form field sidebar directly inside Claude's UI.

Key features

• Interactive PDF viewer — page navigation, zoom, fullscreen, text search with highlights, and a sidebar listing every form field with its fill status
• Form filling & profiles — fill W-9s, I-9s, rental applications, and any fillable PDF; save reusable profiles for repeat forms; validate required fields before saving
• Bulk processing — fill hundreds of PDFs from a CSV in one command; extract structured data from batches back to CSV
• OCR & text extraction — extracts text from scanned documents with OCR fallback; handles encrypted/password-protected PDFs
• Merge, split & organise — combine or split PDFs by page range, rotate pages, reorder pages, all via natural language instructions to Claude
