Social Media Resizing Example

Technical Limitations & Boundaries
- Upscaling limit: Enlarging images beyond 150% of their original dimensions cannot invent new optical detail and may appear soft.
- Aspect ratio distortion: Unchecking "Lock Aspect Ratio" allows non-proportional scaling, which can stretch or squeeze subjects.
- Interpolation: Browser bicubic interpolation balances sharpness and file size.
