Token-efficient
Markdown is far more compact than raw PDF text dumps, so you fit more context into the model's window.
Structure the model understands
Clean headings and lists give the model document hierarchy, which improves grounding and reduces hallucination.
Ready for RAG
Predictable Markdown is easy to chunk and embed into a vector database for retrieval augmented generation.
Frequently asked questions
Are my files uploaded to a server?
No. Conversion runs entirely in your browser using WebAssembly. Your PDF never leaves your device, which makes it safe for contracts, research and other private documents.
Why is Markdown better than raw PDF text for LLMs?
Markdown encodes structure (headings, lists, tables) with very few extra tokens, which helps the model interpret the document and keeps prompts small.
Can I use the output in a RAG pipeline?
Yes. The clean Markdown is straightforward to split into chunks and embed for retrieval, with headings acting as natural chunk boundaries.
