## What it is
ngx_pagespeed is an Apache-licensed Nginx module (originally from Google, incubated at Apache) that automatically applies web performance best practices to pages and assets like CSS, JavaScript, and images without content changes. The original repository is archived; a maintained continuation is offered by We-Amp under ModPageSpeed.

## Use cases
- speed up my nginx-served website automatically
- optimize and recompress images on the fly
- minify and inline CSS and JavaScript without changing my build
- defer image and JavaScript loading to improve page load time
- extend browser cache lifetimes for static assets
- rewrite HTML to apply performance best practices

## When to choose
- you run Nginx and want automatic page-speed optimizations without touching application code
- you need image resizing, minification, and cache tuning handled at the web-server layer

## When to avoid
- you need actively developed software with guaranteed upstream support - the original repo is archived and the continuation requires a commercial license for production
- you use a web server other than Nginx (use mod_pagespeed for Apache instead)
- you prefer doing optimization in your build pipeline or CDN
