PhastPress has the Phast web page optimisation engine by Albert Peschar and Milko Kosturkov at its core.
Image optimization:
- Phast optimizes images using PNG quantization (pngquant) and JPEG recoding (libjpeg-turbo).
- Phast inlines small images (< 512 bytes) in the page.
- Phast converts JPEG images into AVIF or WebP for supporting browsers.
- Phast enables native lazy loading to speed up page loading and save bandwidth.
Asynchronous scripts and stylesheets:
- Phast loads all scripts on your page asynchronously and in a single request, while maintaining full compatibility with legacy scripts, due to our custom script loader.
- Phast proxies external scripts to extend their cache lifetime.
- Phast inlines critical CSS automatically by comparing the rules in your stylesheets with the elements on your page.
- Phast loads non-critical CSS asynchronously and in a single request.
- Phast inlines Google Fonts CSS.
- Phast lazily loads IFrames to prioritize the main page load.
