Choosing the Right Image Format

JPEG (.jpg): The universal standard for vibrant photographs and complex color gradients. It offers excellent compression but does not support transparent backgrounds.

PNG (.png): The go-to choice for crisp logos, icons, and graphics requiring transparent backgrounds. It uses lossless compression, preserving absolute quality at the cost of larger file sizes.

WebP (.webp): A modern, next-generation web image format developed by Google. It provides superior lossless and lossy compression compared to JPEG and PNG, dramatically improving website loading speeds.
