What Is JPG?

JPG is the most widely used format on the internet. It uses lossy compression, which means:
 • Smaller file size
 • Slight decrease in quality
 • Great for photos and complex images

This makes JPG ideal for social media, blogs, and websites where speed matters more than pixel-perfect clarity.

What Is PNG?

PNG uses lossless compression. You keep full image quality, including sharp edges, text, and graphics. PNG also supports transparency, which makes it essential for:
 • Logos
 • Icons
 • UI elements
 • Screenshots
 • Images with text

The trade-off: PNG files are larger than JPG.

What Is WEBP?

WEBP is Google’s modern image format. It provides:
 • Smaller file size than JPG
 • Better quality than JPG at the same size
 • Transparency support like PNG
 • Faster page loading times

WEBP is now supported by all modern browsers and is the best choice for most websites.
