# PDF Processing Guide

## Overview

This guide covers essential PDF processing operations using Python libraries and command-line tools. For advanced features, JavaScript libraries, and detailed examples, see reference.md. If you need to fill out a PDF form, read forms.md and follow its instructions.

## Quick Start

```python
from pypdf import PdfReader, PdfWriter

# Read a PDF
reader = PdfReader("document.pdf")
print(f"Pages: {len(reader.pages)}")

# Extract text
text = ""
for page in reader.pages:
    text += page.extract_text()
```

## Python Libraries

### pypdf - Basic Operations

#### Merge PDFs
```python
from pypdf import PdfWriter, PdfReader

writer = PdfWriter()
for pdf_file in ["doc1.pdf", "doc2.pdf", "doc3.pdf"]:
    reader = PdfReader(pdf_file)
    for page in reader.pages:
        writer.add_page(page)

with open("merged.pdf", "wb") as output:
    writer.write(output)
```

#### Split PDF
```python
reader = PdfReader("input.pdf")
for i, page in enumerate(reader.pages):
    writer = PdfWriter()
    writer.add_page(page)
    with open(f"page_{i+1}.pdf", "wb") as output:
        writer.write(output)
```

#### Extract Metadata
```python
reader = PdfReader("document.pdf")
meta = reader.metadata
print(f"Title: {meta.title}")
print(f"Author: {meta.author}")
print(f"Subject: {meta.subject}")
print(f"Creator: {meta.creator}")
```

#### Rotate Pages
```python
reader = PdfReader("input.pdf")
writer = PdfWriter()

page = reader.pages[0]
page.rotate(90)  # Rotate 90 degrees clockwise
writer.add_page(page)

with open("rotated.pdf", "wb") as output:
    writer.write(output)
```

### pdfplumber - Text and Table Extraction

#### Extract Text with Layout
```python
import pdfplumber

with pdfplumber.open("document.pdf") as pdf:
    for page in pdf.pages:
        text = page.extract_text()
        print(text)
```

#### Extract Tables
```python
with pdfplumber.open("document.pdf") as pdf:
    for i, page in enumerate(pdf.pages):
        tables = page.extract_tables()
        for j, table in enumerate(tables):
            print(f"Table {j+1} on page {i+1}:")
            for row in table:
                print(row)
```

#### Advanced Table Extraction
```python
import pandas as pd

with pdfplumber.open("document.pdf") as pdf:
    all_tables = []
    for page in pdf.pages:
        tables = page.extract_tables()
        for table in tables:
            if table:  # Check if table is not empty
                df = pd.DataFrame(table[1:], columns=table[0])
                all_tables.append(df)

# Combine all tables
if all_tables:
    combined_df = pd.concat(all_tables, ignore_index=True)
    combined_df.to_excel("extracted_tables.xlsx", index=False)
```

### reportlab - Create PDFs

#### Basic PDF Creation
```python
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas

c = canvas.Canvas("hello.pdf", pagesize=letter)
width, height = letter

# Add text
c.drawString(100, height - 100, "Hello World!")
c.drawString(100, height - 120, "This is a PDF created with reportlab")

# Add a line
c.line(100, height - 140, 400, height - 140)

# Save
c.save()
```

#### Create PDF with Multiple Pages
```python
from reportlab.lib.pagesizes import letter
from reportlab.platypus import SimpleDocTemplate, Paragraph, Spacer, PageBreak
from reportlab.lib.styles import getSampleStyleSheet

doc = SimpleDocTemplate("report.pdf", pagesize=letter)
styles = getSampleStyleSheet()
story = []

# Add content
title = Paragraph("Report Title", styles['Title'])
story.append(title)
story.append(Spacer(1, 12))

body = Paragraph("This is the body of the report. " * 20, styles['Normal'])
story.append(body)
story.append(PageBreak())

# Page 2
story.append(Paragraph("Page 2", styles['Heading1']))
story.append(Paragraph("Content for page 2", styles['Normal']))

# Build PDF
doc.build(story)
```

### PyMuPDF (fitz) - All-in-one alternative

Single dependency (`pip install pymupdf`, imported as `pymupdf` or legacy `fitz`) that covers nearly every task in this guide with no system tools and 2–5× the speed of pypdf / pdfplumber / pdf2image. Use it freely when it is the right tool — see the license disclosure rule below.

| Capability | fitz API | Notes |
|---|---|---|
| Open / save | `pymupdf.open(path)` / `doc.save(out, incremental=True)` | Auto-repairs damaged PDFs; supports incremental writes |
| Merge / split | `doc.insert_pdf(src)` / `doc.select([0,2,4])` | In-place page manipulation |
| Rotate pages | `page.set_rotation(90)` | |
| Extract text | `page.get_text("text" \| "blocks" \| "words" \| "dict")` | One API, 4+ granularities |
| Extract tables | `page.find_tables()` → `table.to_pandas()` | Built-in; complex merged cells need PyMuPDF Pro |
| Render page → image | `page.get_pixmap(dpi=200).save(...)` | Replaces pdf2image; no Poppler |
| Extract embedded images | `page.get_images(full=True)` + `pymupdf.Pixmap(doc, xref)` | Replaces `pdfimages` CLI |
| OCR scanned PDFs | `page.get_textpage_ocr(language="eng")` | Built-in Tesseract integration |
| Search text | `page.search_for("keyword")` → list of rects | Pair with annotations for auto-highlight |
| Annotations | `page.add_highlight_annot(rect)` / `add_text_annot(point, ...)` | Pypdf cannot create most annotations |
| **Redaction (irreversible)** | `page.add_redact_annot(rect)` + `page.apply_redactions()` | True content removal — pypdf "black box" still leaks text |
| Watermark | `page.show_pdf_page(rect, src_doc, src_page)` | |
| Encrypt | `doc.save(out, encryption=pymupdf.PDF_ENCRYPT_AES_256, owner_pw=..., user_pw=...)` | AES-256 supported |
| Form fields | `page.widgets()` (read) / `page.add_widget(...)` (create) | Pypdf cannot create widgets |
| Vector graphics | `page.get_drawings()` | Extract paths; pdfplumber cannot |
| Markdown export (RAG/LLM) | `pymupdf4llm.to_markdown(doc)` | Separate package `pip install pymupdf4llm` |

## Command-Line Tools

### pdftotext (Requires poppler-utils)
```bash
# Extract text
pdftotext input.pdf output.txt

# Extract text preserving layout
pdftotext -layout input.pdf output.txt

# Extract specific pages
pdftotext -f 1 -l 5 input.pdf output.txt  # Pages 1-5
```

### qpdf (Requires qpdf)
```bash
# Merge PDFs
qpdf --empty --pages file1.pdf file2.pdf -- merged.pdf

# Split pages
qpdf input.pdf --pages . 1-5 -- pages1-5.pdf
qpdf input.pdf --pages . 6-10 -- pages6-10.pdf

# Rotate pages
qpdf input.pdf output.pdf --rotate=+90:1  # Rotate page 1 by 90 degrees

# Remove password
qpdf --password=mypassword --decrypt encrypted.pdf decrypted.pdf
```

## Common Tasks

### Extract Text from Scanned PDFs
```python
# Requires: pip install pytesseract pdf2image
import pytesseract
from pdf2image import convert_from_path

# Convert PDF to images
images = convert_from_path('scanned.pdf')

# OCR each page
text = ""
for i, image in enumerate(images):
    text += f"Page {i+1}:\n"
    text += pytesseract.image_to_string(image)
    text += "\n\n"

print(text)
```

### Add Watermark
```python
from pypdf import PdfReader, PdfWriter

# Create watermark (or load existing)
watermark = PdfReader("watermark.pdf").pages[0]

# Apply to all pages
reader = PdfReader("document.pdf")
writer = PdfWriter()

for page in reader.pages:
    page.merge_page(watermark)
    writer.add_page(page)

with open("watermarked.pdf", "wb") as output:
    writer.write(output)
```

### Extract Images
```bash
# Using pdfimages (poppler-utils)
pdfimages -j input.pdf output_prefix

# This extracts all images as output_prefix-000.jpg, output_prefix-001.jpg, etc.
```

### Password Protection
```python
from pypdf import PdfReader, PdfWriter

reader = PdfReader("input.pdf")
writer = PdfWriter()

for page in reader.pages:
    writer.add_page(page)

# Add password
writer.encrypt("userpassword", "ownerpassword")

with open("encrypted.pdf", "wb") as output:
    writer.write(output)
```

## Dependencies (install if required and missing)

Verify a dependency before installing (`python -c "import pypdf"` or `command -v qpdf`); install what's missing for the current task.

If installation isn't possible in this environment, **tell the user which dependency is missing and how to install it locally**.

**Python packages**:

```bash
pip install pypdf pdfplumber ...
```

**System tools**:

| Tool | Provides | Used by |
|------|----------|---------|
| `poppler` / `poppler-utils` | `pdftotext`, `pdfimages` | CLI text/image extraction, `pdf2image` |
| `qpdf` | `qpdf` | CLI merge/split/rotate/decrypt |
| `tesseract` | `tesseract` | OCR backend for `pytesseract` |

```bash
# macOS (Homebrew)
brew install poppler qpdf tesseract
```

```powershell
# Windows (winget; run in PowerShell)
winget install --id oschwartz10612.Poppler
winget install --id qpdf.qpdf
winget install --id UB-Mannheim.TesseractOCR
```

After installing on Windows, ensure each tool's `bin` directory is on `PATH` (e.g. `C:\Program Files\poppler-xx\Library\bin`). For `pdf2image`, you may alternatively pass `poppler_path=r"C:\path\to\poppler\bin"` instead of editing `PATH`.
