# Batch Convert Skill

## Overview

This skill enables batch conversion of documents between multiple formats using a unified pipeline. Convert hundreds of files at once with consistent settings, automatic format detection, and parallel processing for maximum efficiency.

## How to Use

1. Specify the source folder or files
2. Choose target format(s)
3. Optionally configure conversion options
4. I'll process all files with progress tracking

**Example prompts:**
- "Convert all PDFs in this folder to Word documents"
- "Batch convert these markdown files to PDF and HTML"
- "Process all Office files and convert to Markdown"
- "Convert this folder of images to a single PDF"
