Why convert PDF to Markdown?

PDF was designed for printing, not for reasoning. When you paste a PDF directly into ChatGPT, Claude or Gemini, the model wastes 60–95% of its context window on layout artifacts: page numbers, headers, footers, broken columns, and invisible glyphs. The result is shallow, error-prone answers and an exploding token bill.

Markdown is the native format of large language models. Converting your PDF to Markdown first lets the model focus on the actual content — chapters, sections, tables, code blocks — instead of fighting layout noise. You typically cut input tokens by 70% and dramatically improve answer quality.

What our PDF to Markdown converter does

• Extracts text with proper reading order (no scrambled multi-column output)
• Detects and preserves headings, lists, blockquotes, and tables as Markdown
• Removes repeating headers, footers, page numbers, and watermarks
• Handles scanned PDFs through optional OCR for image-only documents
• Keeps math notation, code blocks, and inline emphasis (bold, italic, links)
• Outputs UTF-8 plain text — paste it directly into any AI chat or RAG pipeline

The conversion runs in your browser whenever possible and falls back to a serverless function for large or scanned files. No file is stored after the request completes.
