Firecrawl PDF 是什么

Firecrawl PDF Inspector（仓库名 pdf-inspector）是 Firecrawl 开源的一套本地 PDF 分类与文本提取工具。

Firecrawl PDF 目前支持 CLI，收费方式为「开源免费」。安装前建议先到官方渠道确认最新的系统要求与授权条款。

主要功能

• Smart classification — Detect TextBased, Scanned, ImageBased, or Mixed PDFs in ~10-50ms by sampling content streams. Returns a confidence score (0.0-1.0) and per-page OCR routing.
• Table detection — Dual-mode: rectangle-based detection from PDF drawing ops, plus heuristic detection from text alignment. Handles financial tables, footnotes, and continuation tables across pages.
• CID font support — ToUnicode CMap decoding for Type0/Identity-H fonts, UTF-16BE, UTF-8, and Latin-1 encodings.
• Multi-column layout — Automatic detection of newspaper-style columns, sequential reading order, and RTL text support.
• Encoding issue detection — Automatically flags broken font encodings so callers can fall back to OCR.
• Selective OCR — Rust, CLI, Python, and Node can render only pages that need OCR, run PP-OCRv6 Small locally, and preserve per-page provenance and hosted-fallback recommendations.
• Single document load — The document is parsed once and shared between detection and extraction, avoiding redundant I/O.
• Browser WebAssembly — Run the same Rust parser locally in browsers and Web Workers, with embedded CMaps and no server round trip.
