Introducing AnyDoc and pdf-inspector: Firecrawl's open-source document parsing stack

Firecrawl has introduced two open-source Rust libraries intended to simplify document-to-Markdown conversion for AI pipelines: pdf-inspector for PDFs and AnyDoc for 14 non-PDF formats, including Office documents, spreadsheets, presentations, e-books, and CSV files. pdf-inspector examines PDF internals without rendering pages, classifies pages as text-based or requiring OCR, extracts native text while preserving reading order, and routes only scanned or image-heavy pages to vision processing, a design Firecrawl says has made its hosted PDF parsing engine 3.5 to 5 times faster. AnyDoc provides a single dependency-free local conversion interface for supported formats and, according to Firecrawl’s benchmark of 94 documents, achieved complete format coverage, a 4.6-millisecond median conversion time, and the highest overall quality score among compared tools, though the company notes that its corpus was internally created and Mammoth performed better on DOCX completeness alone. Both libraries require no API keys or system dependencies, output Markdown, are available as separate repositories, and already support Firecrawl’s /parse and /scrape endpoints, where PDFs use pdf-inspector and non-PDF files use AnyDoc.
