PNG vs JPG: Detailed Comparison

Understand the core parameters of PNG and JPG formats to improve user experiences and site speed budgets.

The choice between PNG and JPG (JPEG) is one of the oldest design decisions. While both formats have been web standards for decades, they serve entirely opposite use cases.

Feature PNG JPG / JPEG
Compression Type Lossless (no quality loss) Lossy (discards detail)
Transparency Yes No
Ideal Content Graphics, screenshots, text Photographs, colorful banners
Average File Size Heavy Lightweight

When to choose PNG

Choose PNG when you require transparency and cannot afford compression artifacts. This includes website logos, graphics with crisp margins, software screenshots, and icons.

When to choose JPG

Choose JPG when saving photos or complex landscape images. JPG sacrifices microscopic color information to save massive amounts of data, leading to lightweight files that load instantly.
