PDF Splitter

A simple Node.js script to split a PDF into individual pages and create JPEG thumbnails. Split PDF to individual pages with inherited file name. In some business cases is beneficial to use chunking strategy based on individual pages especially for semantic search when the goal is to show specific page rather than compile response to user request. PDF Splitter is right tool for initial PDF processing. After splitting you can use another my tool for text and image extraction, MistralOCR.

• Homebrew: Required for installing Poppler on macOS.
• Poppler: The script uses the pdftocairo command-line tool. Install via Homebrew:
