PDF4LLM - PDF4LLM (original) (raw)
Your LLM is only as good as the content you feed it. Most PDF libraries hand you a wall of unstructured text and leave you to figure out the rest. PDF4LLM gives you something you can actually use — clean Markdown, structured JSON, or plain text, with reading order preserved, tables intact, and images handled — in a single function call. Built on MuPDF, it is trusted by developers building production RAG pipelines, document intelligence systems, and LLM-powered applications worldwide.
Everything your pipeline needs. Nothing it doesn’t.
Three output formats. One consistent API.
Whether you’re building a RAG pipeline, a custom document intelligence system, or a data extraction workflow, PDF4LLM produces the format you need.
| Format | Best for |
|---|---|
| Markdown | LLM ingestion, RAG pipelines, and human-readable output with structure preserved |
| JSON | Custom pipelines that need bounding boxes, font data, and per-block layout metadata |
| Plain Text | Search indexing, NLP preprocessing, and tools that don’t need formatting |
Works with the documents you already have
Trusted at every scale
PDF4LLM is built for production. It handles everything from single-page invoices to thousands of pages of legal, financial, or technical documentation — with predictable performance and output quality you can rely on.
