WHAT IS IT?
PaddleOCR is an open-source OCR toolkit that turns images and PDFs into structured data (Markdown, JSON) that an LLM can ingest directly. It goes well beyond plain text recognition: it parses entire documents — page layout, tables, formulas, charts and even ancient manuscripts. It's the bridge between your scans and your AI pipelines.
WHY IS IT INTERESTING?
- Seriously multilingual: 100+ languages supported, with the unified PP-OCRv6 model covering 50 of them at once.
- Full document parsing: not just text — it recognizes tables, math formulas, charts and overall page structure.
- LLM-ready output: emits Markdown or JSON straight away, ready to feed a RAG pipeline with no post-processing.
- Lightweight and fast: compact models (1.5M to 34.5M parameters) and up to 5.2× speedup on CPU inference.
- Integrated ecosystem: native hooks into Dify, RAGFlow and other AI platforms.
USE CASES
- Bulk conversion of PDFs and scans into clean Markdown.
- Data preparation for RAG pipelines and knowledge bases.
- Information extraction from invoices, forms and administrative documents.
- Scene text recognition in the wild (photos, signs, screenshots).
- Digitization of ancient documents or complex handwriting.
