Usage
Run the conversion script with one or more image URLs:
python .claude/skills/image-to-webp/scripts/convert.py <url> [url2] [url3] [options]
Parameters
| Parameter | Description | Default |
|---|---|---|
urls |
One or more image URLs to download | Required |
--output |
Output filename prefix (without extension) | Auto-generated from URL |
--width |
Target width in pixels | 800 |
--height |
Target height in pixels | 600 |
--quality |
WebP quality 1-100 | 85 |
--dest |
Destination folder | ./public |
--keep-ratio |
Maintain aspect ratio (fit within dimensions) | Off (crops to fill) |
Examples
Basic usage - download, resize to 800x600, convert to WebP
python .claude/skills/image-to-webp/scripts/convert.py https://images.pexels.com/photos/1640777/pexels-photo-1640777.jpeg
Batch processing multiple URLs
python .claude/skills/image-to-webp/scripts/convert.py \
https://images.pexels.com/photos/1640777/pexels-photo-1640777.jpeg \
https://images.pexels.com/photos/842571/pexels-photo-842571.jpeg
Custom dimensions (e.g., for hero images)
python .claude/skills/image-to-webp/scripts/convert.py \
https://images.pexels.com/photos/1640777/pexels-photo-1640777.jpeg \
--width 1920 --height 1080
Custom output name and quality
python .claude/skills/image-to-webp/scripts/convert.py \
https://images.pexels.com/photos/1640777/pexels-photo-1640777.jpeg \
--output hero-image --quality 90
Keep aspect ratio (fits within 800x600 without cropping)
python .claude/skills/image-to-webp/scripts/convert.py \
https://images.pexels.com/photos/1640777/pexels-photo-1640777.jpeg \
--keep-ratio
Save to custom directory
python .claude/skills/image-to-webp/scripts/convert.py \
https://images.pexels.com/photos/1640777/pexels-photo-1640777.jpeg \
--dest ./public/images
Output
The script outputs the path to each created WebP file and reports the file size. For batch operations, it shows progress and a summary at the end.
Dependencies
Requires Python 3 with Pillow and requests libraries. If not installed, run:
pip install Pillow requests
Notes
- Auto-generated filenames are derived from the URL or use sequential numbering for batches
- WebP format provides excellent compression while maintaining quality
- Default 800x600 at quality 85 typically produces files of 50-150KB
- The
--keep-ratioflag prevents cropping by fitting the image within the target dimensions
