# PNG → WebP Compressor
Converts PNG images to WebP format via ffmpeg. Simple, lossy/lossless WebP encoding with configurable quality.
## Script Directory
Scripts in `scripts/` subdirectory. `{baseDir}` = this SKILL.md's directory path. Replace `{baseDir}` with actual value.
| Script | Purpose |
|--------|---------|
| `scripts/compress.ts` | PNG → WebP conversion CLI |
## Usage
```bash
bun {baseDir}/scripts/compress.ts <input> [options]
```
## Options
| Option | Short | Description | Default |
|--------|-------|-------------|---------|
| `<input>` | | PNG file path(s) — supports glob patterns | Required |
| `--output` | `-o` | Output file or directory | Same path, .webp ext |
| `--quality` | `-q` | Quality 0–100 | 80 |
| `--lossless` | `-l` | Lossless WebP encoding (ignores quality) | false |
| `--keep` | `-k` | Keep original PNG | false |
## Examples
```bash
# Basic conversion (quality 80)
bun {baseDir}/scripts/compress.ts image.png
# High quality
bun {baseDir}/scripts/compress.ts image.png -q 90
# Lossless
bun {baseDir}/scripts/compress.ts image.png --lossless
# Keep original
bun {baseDir}/scripts/compress.ts image.png -k
# Convert all PNGs in a directory
bun {baseDir}/scripts/compress.ts "images/*.png"
# Custom output path
bun {baseDir}/scripts/compress.ts image.png -o output.webp
```
**Output**:
```
image.png → image.webp (1024KB → 89KB, 91% reduction)
```
