pdf-inspector
Fast Rust library for PDF inspection, classification
...The converter produces clean Markdown with headings, lists, code blocks, links, page breaks, and formatted tables. It supports CID fonts, several encodings, right-to-left text, and automatic detection of broken font mappings. The same core is available through Rust, Python, Node.js, browser WebAssembly, and command-line interfaces. It is designed for local document pipelines that need fast routing before using slower OCR services.
