**Version:** 0.1.2
**Axioma Tools**

Strips metadata from images while preserving the actual image data.

## What this skill does

- JPEG: strips EXIF, ICC profile, XMP, IPTC
- PNG: strips tEXt, zTXt, iTXt, eXIf chunks
- GIF: strips comment extensions
- Preserves image pixels (no re-encoding)
- Bytes-in, bytes-out

## When to use this skill

- ✅ Strip GPS coordinates before sharing photos
- ✅ Remove camera serial numbers
- ✅ Sanitize before publishing to web
- ❌ Re-encode/resize images (use Pillow)
- ❌ View EXIF (use exiftool)

## Usage

```bash
python3 axiom_image_metadata_stripper.py photo.jpg -o photo-clean.jpg
python3 axiom_image_metadata_stripper.py ./photos/ --output-dir ./clean/
```

```python
from axiom_image_metadata_stripper import strip_metadata
clean_bytes = strip_metadata(open('photo.jpg', 'rb').read())
```
