About StaticOptimizer

From the official readme · v1.0.6

Description

StaticOptimizer is a static file optimization cloud service that speeds up your site by optimizing and serving (the selected) static files from your site.
The service optimizes & compresses the files automatically.
No database or files changes are performed therefore there’s no risk if you want to uninstall the plugin later (… but why would you?)
If our optimization server are down (upgrade, maintenance or outage) your original files will be loaded instead.

Features / Benefits

  • Simple, efficient and free to use
  • The free plan allows you to have images up to 5mb and up to 1600px wide or tall
  • Easy to set up. Just get your API key and you’re good to go.
  • Automatic js and css minification & compression
  • Automatic image optimization (gif, jpeg, png, svg)
  • Files are reloaded only when they are changed on your server (or deleted from ours).
  • Automatic conversion to webp
  • Our servers check and if the visitor’s browser supports webp we’ll serve that file otherwise the optimized version.
  • Responsive Images (from srcset) are also processed
  • Background images url() are also processed
  • We’ve put extra efforts to make this plugin as efficient as possible.
  • The code in script blocks is preserved
  • Sandbox/test/development subdomains are automatically authorized if the main domain is authorized. Test subdomains are: test, testing, sandbox, dev, local, stage, staging
  • SEO: Our servers return canonical header to tell which is the source file. Link: https://example.com/images/image.png; rel=”canonical”
  • Select if you want your site to be optimized by servers in Europe or North America
  • No lock-in = after deactivation, all files will work and load from your current host and no data loss

How it works

After you get your API key the plugin will install as a system (mu-plugin) and will correct the location where the selected files are loaded from.
During the plugin configuration you can tell the plugin which file types you’d like to be optimized.
By default only images are selected for optimization. You can also select js, & css files to be optimized as well.
The first time our servers get a file it will be downloaded and optimized. Because this operation can take several seconds
your users will be redirected back to the original file that was requested. Any subsequent requests will be served from our servers.

Who is this plugin for?

People who have lots of images on their site such online stores, photographers, real estate agents.
