# PDF & Document Extraction
For DOCX: use `python-docx` (parses actual document structure, far better than OCR).
For PPTX: see the `powerpoint` skill (uses `python-pptx` with full slide/notes support).
This skill covers **PDFs and scanned documents**.
## Step 1: Remote URL Available?
If the document has a URL, download it first, then extract locally:
```bash
curl -fsSL -o /tmp/doc.pdf "https://arxiv.org/pdf/2402.03300"
curl -fsSL -o /tmp/report.pdf "https://example.com/report.pdf"
```
Then run pymupdf/marker on the downloaded file (steps below). If your client
has a built-in web-fetch / URL-to-markdown tool, you can use that for a quick
text grab instead — but `curl` + pymupdf works everywhere with no extra deps.
## Step 2: Choose Local Extractor
