LiteParse

LiteParse is an open-source PDF parsing tool designed for speed and lightweight operation. It performs spatial text parsing using PDFium, generates bounding boxes for precise text positioning, and includes flexible OCR capabilities with built-in Tesseract support or integration with external OCR servers. The tool runs entirely locally without cloud dependencies or proprietary LLM features.

LiteParse outputs structured Markdown, JSON, or plain text and includes complexity detection to route documents appropriately before full parsing. It supports multiple languages via Rust, Node.js, TypeScript, Python, and browser-based WebAssembly. The project includes worker pool mode for true parallelism and per-parse timeouts. According to the repository, it was built with Claude AI coding tools.
