PhastPress

PhastPress is a WordPress plugin that uses advanced techniques to optimize web pages, scripts, stylesheets, and images to improve load times and conform to Google PageSpeed Insights and GTmetrix recommendations. The plugin optimizes images using PNG quantization and JPEG recoding, inlines small images, converts JPEG images into WebP, and enables native lazy loading. It also loads all scripts asynchronously and in a single request, proxies external scripts, inlines critical CSS, loads non-critical CSS asynchronously, inlines Google Fonts CSS, and lazily loads IFrames. The plugin requires no configuration and can significantly improve a site's score.
