Best Practices & Key Recommendations
- Fix phone camera orientation metadata (EXIF tags) by rotating and saving clean standard pixels.
- When using free angle rotation, transparent padding is added around corners for PNG/WEBP, and solid white for JPG.
Troubleshooting & Common Issues
- Corners have white padding after custom angle rotation: Save as PNG to maintain transparent corners instead of solid background padding.
- Photo reverts to wrong orientation on phone: The tool bakes pixel rotations into the image data, stripping misleading EXIF orientation flags.
