What each one is
Docling
Docling parses PDFs, DOCX, PPTX and images into structured representations with layout, tables and reading order, designed to plug straight into RAG frameworks.
- Rich structured output: layout, tables, reading order
- First-class integrations with LangChain and LlamaIndex
- Backed by IBM Research, MIT-licensed
PDF to MD Converter
A hosted web page that turns text-layer PDFs into Markdown in the browser tab using Mozilla's pdf.js: drop a file, preview, then copy or download the .md. Reverse conversion and a Batch page are also linked. Closed source, free to try, no pricing page. Note before using it: the "nothing is uploaded" claim covers the homepage workspace only, not the linked Batch page, and there is no OCR, so image-only scans come out empty.
- Conversion runs in the browser tab with Mozilla's pdf.js
- No account, and the page states nothing is sent to its servers
- Keeps headings, paragraphs, lists, simple tables and code blocks
