Image Compression Formula

Since PNG to JPEG conversion involves image compression, the following calculations are commonly used.

Compression Ratio Formula

Compression Ratio (%) = (Compressed File Size ÷ Original File Size) × 100

File Size Reduction Formula

Reduction (%) = ((Original Size − Compressed Size) ÷ Original Size) × 100

Estimated Output Size Formula

Estimated Output Size = Original Size × Compression Ratio

Example 1 – PNG to JPG

Original Image:

PNG

Size:

5 MB

Converted Image:

JPG

Size:

2 MB

Reduction:

((5 − 2) ÷ 5) × 100

= 60% File Size Reduction
