The Evolution of Web Image Formats
For over two decades, the Portable Network Graphics (PNG) format was the undisputed king of web graphics requiring lossless transparency.

In real-world benchmarks, WebP achieves an average of 26% smaller file sizes compared to PNG while preserving identical visual fidelity and full alpha transparency channels.
