Serve AVIF or WebP at the right dimensions for the screen — that usually cuts images by more than half.
This estimates file transfer only. It excludes server response, JavaScript execution and rendering — real load is slower, never faster.
How to use it
- Set the sliders to your page's weight by resource type.
- Read the times for each connection on the right.
- Look at which resource is heaviest — usually the images.
- Cut the heaviest first; that is where the gain is.
