docling vs pdf-inspector
Document conversion and PDF extraction tools compared
docling converts many document and media formats into structured output, while pdf-inspector focuses on classifying PDFs and extracting their text as Markdown. Both support local processing, but docling covers broader input and export workflows, whereas pdf-inspector emphasizes page-level PDF analysis and selective OCR routing.
docling: Convert Documents into Structured Content
Docling parses documents such as PDFs, Word files, spreadsheets, and images into structured content for applications and generative AI workflows. It offers local processing, a Python library, and a command-line interface.
pdf-inspector: Classify PDFs and Extract Text as Markdown
pdf-inspector is a Rust library and set of bindings for classifying PDFs, extracting positioned text, and converting documents to Markdown. It helps processing pipelines route scanned pages to OCR while handling text-based pages locally.
