LLMs and RAG systems work better with structured text. Markdown keeps headings, lists and paragraphs.

Why in-browser

Internal docs, contracts and research may contain trade secrets. Converting on PDFX keeps files on your device.

Private RAG flow

  1. PDF → Markdown on PDFX
  2. Chunk .md in your local pipeline
  3. Embeddings on infrastructure you control

Limits

Scanned image-only PDFs need OCR — limited in-browser. Native text PDFs work great.

For image-only sources, start with how OCR turns a scan into searchable text. For tabular content, follow the dedicated PDF-table-to-Excel workflow and validate values before feeding them to an LLM.
