3. Professional Cropping Advice
1:1 Square
✓
Headshot headroom: Leave approximately 10% headroom above the crown of the head for natural, well-balanced portrait framing.
✓
Trimming receipt backgrounds: Crop away desk tables from receipt photos before submitting expense reports.
✓
Targeting specific file sizes: Trimming excess pixels naturally lowers file weight; if strict KB limits apply, pass the cropped result to [Compress Image].
