The Problem
Logos often look blurry or pixelated when displayed at full size. The browser stretches or compresses the image, resulting in poor quality.

Our Logo Analysis
Header Logo: 350×54px (6.48:1 aspect ratio)
Footer Logo: 795×157px (5.06:1 aspect ratio)

The Solution
Display high-resolution images at smaller sizes. This gives the browser more pixels to work with, resulting in crisp edges, clear details, and professional appearance.
Example: A 350×54px image displayed at 52×8px gives each screen pixel 6.7 image pixels, making it much sharper.
