# PDF Merge & Split

Combine multiple PDF files into one or split PDFs into separate documents.

## Overview

This skill helps you:
- Merge multiple PDFs into a single file
- Split PDFs by page ranges
- Extract specific pages
- Reorder pages within a PDF
- Create custom arrangements

## How to Use

### Merge PDFs
```
"Merge these 3 PDFs into one file"
"Combine document1.pdf and document2.pdf"
"Join all PDFs in this folder in alphabetical order"
```

### Split PDF
```
"Split this PDF into individual pages"
"Extract pages 5-10 from this PDF"
"Split this PDF every 5 pages"
```

### Reorder
```
"Move page 3 to the end"
"Reorder pages: 1, 3, 2, 4, 5"
"Reverse the page order"
```
