# ImageMagick Image Conversion

**Project:** Project-independent
**Gitignored:** Yes

## Trigger

Use this skill when users request image manipulation tasks including:
- Converting between image formats (PNG, JPEG, WebP, GIF, TIFF, etc.)
- Resizing images (dimensions, percentages, aspect ratios)
- Batch processing multiple images
- Adjusting image quality and compression
- Creating thumbnails
- Basic image transformations (rotate, flip, crop)

## Overview

ImageMagick is a powerful command-line tool for image processing. This skill provides guidance for using the `magick` command to perform common image conversion and manipulation tasks.

**Key Command Pattern:**
```bash
magick input-file [options] output-file
```

## Common Use Cases

### Format Conversion

**Basic format conversion:**
```bash
magick image.jpg image.png
magick photo.png photo.webp
```

**Batch convert all JPEGs to PNG:**
```bash
magick mogrify -format png *.jpg
```

**Convert with specific output directory:**
```bash
mkdir -p output
magick mogrify -format webp -path output/ *.jpg
```

### Resizing Images

**Resize by percentage:**
```bash
magick image.jpg -resize 50% output.jpg
```

**Resize to specific width (maintain aspect ratio):**
```bash
magick image.jpg -resize 800x output.jpg
```

**Resize to specific height (maintain aspect ratio):**
```bash
magick image.jpg -resize x600 output.jpg
```

**Resize to fit within dimensions (maintain aspect ratio):**
```bash
magick image.jpg -resize 800x600 output.jpg
```

**Resize to exact dimensions (ignore aspect ratio):**
```bash
magick image.jpg -resize 800x600! output.jpg
```

**Resize only if larger:**
```bash
magick image.jpg -resize '800x600>' output.jpg
```

**Resize only if smaller:**
```bash
magick image.jpg -resize '800x600<' output.jpg
```

### Quality and Compression

**Set JPEG quality (1-100, default 92):**
```bash
magick image.jpg -quality 85 output.jpg
```

**Optimize PNG compression:**
```bash
magick image.png -quality 95 output.png
```
