Deep Dive into Web Formats
1. JPEG (Joint Photographic Experts Group)
JPEG has been a web standard for decades. It excels at compressing rich photography with millions of colors into manageable sizes. However, it does not support transparent backgrounds and loses sharpness around sharp text or vector logos.
2. PNG (Portable Network Graphics)
PNG uses lossless compression, meaning every pixel is preserved perfectly. It is ideal for transparent icons, brand logos, and user interface screenshots. The downside? Photographic PNG files can easily balloon to several megabytes.
3. WebP (The Modern Standard)
Developed by Google, WebP provides 25% to 35% smaller file sizes than comparable JPEGs and PNGs while retaining visual fidelity and supporting alpha transparency. WebP is supported by 98%+ of global desktop and mobile browsers.
