Understanding Image Size
File Size (KB/MB): This is the most critical factor for website speed. Smaller file sizes load faster, improving SEO and user experience. This is measured in bytes and is affected by compression.
Pixel Dimensions (Width x Height): This is the actual resolution of the image. A massive resolution (e.g., 6000x4000) is unnecessary for a small thumbnail and wastes bandwidth.
Total Pixels (MP): Megapixels is the width multiplied by the height, divided by a million. It gives you a sense of the image's raw quality or print potential.
