# Working with PDFs
## Reading a PDF
- To **understand or summarise** a PDF the user points you at, use the
`read_file` tool with its path. AG2 Assistant hands PDFs to the model as visual
content, so this works even for **scanned PDFs with no text layer** (forms,
signed documents, image scans). Ask permission the first time if prompted.
- For a **born-digital PDF where you need the exact text** (to quote precisely,
count, or post-process), extract the text via code execution instead (below).
## Manipulating a PDF (code execution)
Use the code-execution tool. Prefer `pypdf` (pure-Python, no system deps); fall
back to `pdfplumber` for tables. Install on first use if missing
(`pip install pypdf`).
- **Extract text:**
```python
from pypdf import PdfReader
r = PdfReader("in.pdf")
print("\n".join(page.extract_text() or "" for page in r.pages))
```
- **Split / select pages:**
```python
from pypdf import PdfReader, PdfWriter
r = PdfReader("in.pdf")
w = PdfWriter()
for i in (0, 1, 2): # first three pages
w.add_page(r.pages[i])
with open("out.pdf", "wb") as f:
w.write(f)
```
- **Merge:** add pages from several `PdfReader`s into one `PdfWriter`.
- **Tables:** `pdfplumber` → `page.extract_tables()` is more reliable than plain
text extraction for tabular data.
## Tips
- If text extraction returns empty strings, the PDF is scanned/image-only — read
it visually with `read_file` instead.
- Always tell the user where you wrote any output file.
- Don't fabricate content you couldn't extract — say what failed and ask how to
proceed.
