Balancing Dimensions and Compression Ratio #

Shrinking a 5 MB smartphone photo down to 100 KB requires two coordinated adjustments:

1. Dimension Downscaling: Modern smartphones capture images at 4000×3000 pixels. A portal thumbnail only displays at 300×400 pixels. Scaling dimensions down eliminates millions of redundant pixels.
2. Quantization Quality Tuning: Iteratively tuning the compression quality parameter finds the optimal balance where file weight drops below 100 KB while facial features and document text remain sharp.
