# Marp CLI

Convert Markdown to presentations via CLI. Output HTML, PDF, PowerPoint (PPTX), and images (PNG/JPEG).

**Browser requirement:** Conversions marked with 🌐 require a compatible browser (Chrome, Edge, or Firefox) installed on your system.

## Quick Start

```bash
# Convert to HTML
marp slide-deck.md

# Convert to PDF (requires browser)
marp --pdf slide-deck.md

# Convert to PowerPoint
marp --pptx slide-deck.md

# Convert to images
marp --images png slide-deck.md
```

📖 **Detailed guide:** [QUICKSTART.md](QUICKSTART.md)

## Format conversion

### HTML
```bash
marp slide-deck.md
marp slide-deck.md -o output.html
```

### PDF 🌐
```bash
marp --pdf slide-deck.md
marp slide-deck.md -o output.pdf

# With PDF outlines
marp --pdf --pdf-outlines slide-deck.md

# Includes presenter notes as annotations on lower-left
marp --pdf --pdf-notes slide-deck.md
```

### PowerPoint (PPTX) 🌐
```bash
marp --pptx slide-deck.md
marp slide-deck.md -o output.pptx

# Editable PPTX (experimental, requires LibreOffice Impress)
marp --pptx --pptx-editable slide-deck.md
```

### Images 🌐
```bash
# Multiple images
marp --images png slide-deck.md
marp --images jpeg slide-deck.md

# Title slide image only
marp --image png slide-deck.md
marp slide-deck.md -o output.png

# High resolution (scale factor)
marp slide-deck.md -o title.png --image-scale 2
```

### Presenter notes
```bash
marp --notes slide-deck.md
marp slide-deck.md -o output.txt
```

## Watch mode

```bash
# Watch file and auto-convert on changes
marp -w slide-deck.md

# Watch with browser preview
marp -w -p slide-deck.md
```

## Server mode

```bash
# Serve directory with on-demand conversion
marp -s ./slides

# Specify port via environment
PORT=5000 marp -s ./slides

# Access converted formats via query strings
# http://localhost:8080/deck.md?pdf
# http://localhost:8080/deck.md?pptx
```

## Preview window

```bash
# Open preview window (automatically enables watch mode)
marp -p slide-deck.md

# Preview with PDF output
marp -p --pdf slide-deck.md
```

## Multiple files

```bash
# Convert multiple files
marp slide1.md slide2.md slide3.md

# Convert directory
marp ./slides/

# Use glob patterns
marp **/*.md

# Convert with parallelism (default: 5 concurrent)
marp -P 10 ./*.md

# Disable parallelism
marp --no-parallel ./*.md
```
