# Image Compressor
|
||||
|
||||
Cross-platform image compression with WebP default output, PNG-to-PNG support, preferring system tools with Sharp fallback.
|
||||
|
||||
## Script Directory
|
||||
|
||||
**Important**: All scripts are located in the `scripts/` subdirectory of this skill.
|
||||
|
||||
**Agent Execution Instructions**:
|
||||
1. Determine this SKILL.md file's directory path as `SKILL_DIR`
|
||||
2. Script path = `${SKILL_DIR}/scripts/<script-name>.ts`
|
||||
3. Replace all `${SKILL_DIR}` in this document with the actual path
|
||||
|
||||
**Script Reference**:
|
||||
| Script | Purpose |
|
||||
|--------|---------|
|
||||
| `scripts/main.ts` | CLI entry point for image compression |
|
||||
|
||||
## Quick Start
|
||||
|
||||
```bash
|
||||
# Compress to WebP (default)
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts image.png
|
||||
|
||||
# Keep original format (PNG → PNG)
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts image.png --format png
|
||||
|
||||
# Custom quality
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts image.png -q 75
|
||||
|
||||
# Process directory
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts ./images/ -r
|
||||
```
|
||||
|
||||
## Commands
|
||||
|
||||
### Single File Compression
|
||||
|
||||
```bash
|
||||
# Basic (converts to WebP, replaces original)
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts image.png
|
||||
|
||||
# Custom output path
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts image.png -o compressed.webp
|
||||
|
||||
# Keep original file
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts image.png --keep
|
||||
|
||||
# Custom quality (0-100, default: 80)
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts image.png -q 75
|
||||
|
||||
# Keep original format
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts image.png -f png
|
||||
```
|
||||
|
||||
### Directory Processing
|
||||
|
||||
```bash
|
||||
# Process all images in directory
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts ./images/
|
||||
|
||||
# Recursive processing
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts ./images/ -r
|
||||
|
||||
# With custom quality
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts ./images/ -r -q 75
|
||||
```
|
||||
|
||||
### Output Formats
|
||||
|
||||
```bash
|
||||
# Plain text (default)
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts image.png
|
||||
|
||||
# JSON output
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts image.png --json
|
||||
```
|
||||
|
||||
## Options
|
||||
|
||||
| Option | Short | Description | Default |
|
||||
|--------|-------|-------------|---------|
|
||||
| `<input>` | | Input file or directory | Required |
|
||||
| `--output <path>` | `-o` | Output path | Same path, new extension |
|
||||
| `--format <fmt>` | `-f` | webp, png, jpeg | webp |
|
||||
| `--quality <n>` | `-q` | Quality 0-100 | 80 |
|
||||
| `--keep` | `-k` | Keep original file | false |
|
||||
| `--recursive` | `-r` | Process directories recursively | false |
|
||||
| `--json` | | JSON output | false |
|
||||
| `--help` | `-h` | Show help | |
|
||||
|
||||
## Compressor Selection
|
||||
|
||||
Priority order (auto-detected):
|
||||
|
||||
1. **sips** (macOS built-in, WebP support since macOS 11)
|
||||
2. **cwebp** (Google's official WebP tool)
|
||||
3. **ImageMagick** (`convert` command)
|
||||
4. **Sharp** (npm package, auto-installed by Bun)
|
||||
|
||||
The skill automatically selects the best available compressor.
|
||||
|
||||
## Output Format
|
||||
|
||||
### Text Mode (default)
|
||||
|
||||
```
|
||||
image.png → image.webp (245KB → 89KB, 64% reduction)
|
||||
```
|
||||
|
||||
### JSON Mode
|
||||
|
||||
```json
|
||||
{
|
||||

|
||||
}
|
||||
```
|
||||
|
||||

||||
|
||||
```json
|
||||

|
||||
|
||||
## Examples
|
||||
|
||||
### Compress single image
|
||||
|
||||
```bash
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts photo.png
|
||||
# photo.png → photo.webp (1.2MB → 340KB, 72% reduction)
|
||||
```
|
||||
|
||||
### Compress with custom quality
|
||||
|
||||
```bash
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts photo.png -q 60
|
||||
# photo.png → photo.webp (1.2MB → 280KB, 77% reduction)
|
||||
```
|
||||
|
||||
### Keep original format
|
||||
|
||||
```bash
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts screenshot.png -f png --keep
|
||||
# screenshot.png → screenshot-compressed.png (500KB → 380KB, 24% reduction)
|
||||
```
|
||||
|
||||
### Process entire directory
|
||||
|
||||
```bash
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts ./screenshots/ -r
|
||||
# Processed 15 files: 12.5MB → 4.2MB (66% reduction)
|
||||
```
|
||||
|
||||
### Get JSON for scripting
|
||||
|
||||
```bash
|
||||
npx -y bun ${SKILL_DIR}/scripts/main.ts image.png --json | jq '.ratio'
|
||||
```
|
||||
|
||||
## Extension Support
|
||||
|
||||
Custom configurations via EXTEND.md.
|
||||
|
||||
**Check paths** (priority order):
|
||||
1. `.baoyu-skills/baoyu-compress-image/EXTEND.md` (project)
|
||||
2. `~/.baoyu-skills/baoyu-compress-image/EXTEND.md` (user)
|
||||
|
||||
If found, load before workflow. Extension content overrides defaults.
