WHAT IS PNG?

PNG (Portable Network Graphics) is a lossless image format that preserves crisp edges and supports full alpha transparency. It’s ideal for UI elements, logos, icons, and graphics that need a clean look on any background. PNG avoids compression artifacts but can be larger than lossy formats.

WHAT IS WEBP?
