PDF & Document to Markdown (LLM / RAG ready)

Turn PDFs, Word, PowerPoint, Excel, HTML, CSV and EPUB files into clean Markdown or plain text that you can feed straight into an LLM, a vector database or a search index.

Give it a list of document URLs. For each one you get:

• Markdown with structure: headings detected from font size and weight, paragraphs re-joined across line breaks, hyphenation repaired, bullet lists, and tables rendered as Markdown tables. That covers fully ruled tables and tables drawn with horizontal lines only, the usual style in research papers and reports.
• Correct reading order: two-column papers are read one column at a time. Every PDF result is checked against the PDF's own text layer, and you get a warning if words seem to be missing.
• Clean output: rotated watermarks and stamps ("PAID", "DRAFT") are removed, and Chinese and Japanese text comes without stray spaces between characters
• OCR for scanned PDFs: pages without a text layer are read with Tesseract OCR automatically, in 41 languages
• Password-protected PDFs: give the password once and it's stored encrypted
• Clean text: running headers, footers and page numbers removed (optional)
• Metadata: title, author, subject, creator, dates, page count, file size, SHA-256
• RAG chunks (optional): chunks of roughly the size you choose, split on paragraph boundaries, each tagged with the headings it sits under
• Tables as JSON (optional): every detected PDF table as rows of cells

Typical uses

• Ingesting reports, papers, manuals and contracts into a RAG pipeline
• Bulk-converting document links found by another scraper
• Making PDFs searchable or diff-able as text

Input

Field	What it does
Document URLs	Direct links to files. The type is detected from the content, not just the extension.
Output format	markdown, text or both
Chunk size / overlap	Set a chunk size to get chunks ready for embedding
PDF page range	e.g. 1-5,8,10-
PDF password	Opens password-protected PDFs. Stored encrypted.
Max pages per PDF	Caps work and cost on very long files
OCR mode / languages	auto reads scanned pages only; choose the document languages

Output (one item per document)

{
  "url": "https://arxiv.org/pdf/1706.03762",
  "status": "ok",
  "fileType": "pdf",
  "pageCount": 15,
  "pagesProcessed": 15,
  "metadata": {"creator": "LaTeX with hyperref", "producer": "pdfTeX-1.40.25"},
  "markdown": "# Attention Is All You Need\n\n## Abstract\n\nThe dominant sequence transduction models ...",
  "chunks": [{"index": 0, "headings": ["Attention Is All You Need", "Abstract"], "text": "..."}],
  "warnings": []
}

Failed downloads or unreadable files come back with status: "error" and a reason. They are never charged.

Use it from code

Call it as an API and get the results back as JSON in one request:

curl -X POST "https://api.apify.com/v2/acts/prometheus-maker~pdf-document-to-markdown/run-sync-get-dataset-items" \
  -H "Authorization: Bearer $APIFY_TOKEN" -H "Content-Type: application/json" \
  -d '{"startUrls": [{"url": "https://arxiv.org/pdf/1706.03762"}], "chunkSize": 1500}'

A tested Python example is in pdf_to_markdown.py in the examples repo.

Pricing

Pay per use: a small fee per converted document plus a small fee per page. PowerPoint counts one page per slide; files without pages (Word, Excel, HTML, CSV, EPUB) count one page per 3,000 characters of text, about one printed page. OCR pages cost extra because they need far more compute. Failed documents cost nothing. Use Max pages per PDF to cap the cost of very long files.

Limits (honest list)

• OCR quality depends on scan quality; OCR output is plain paragraphs (no headings or tables).
• Tables with no lines at all come out as text, not as Markdown tables.
• Math in PDFs comes out as plain text (no LaTeX). Equations in Word files do become LaTeX, like $β_{0}+β_{t}x_{t}$.
• Password-protected Word, Excel and PowerPoint files, and old .doc/.ppt files, are not supported: you get a clear error and pay nothing. Old .xls spreadsheets work.
• Some damaged or unusual PDFs can't be read by the main engine. Those are read with a second engine (PDFium, the one in Chrome) as plain text, with a warning in warnings.
• Files up to 100 MB. Very large Word files can need more memory: one whose text alone was 12.5 MB used 791 MB, so give runs with such files 2 GB.
