The work

What I own

I own the plugin end to end: architecture, releases, code review, support and product direction.

One-click image optimization

Existing media is compressed and served in modern formats without the site owner touching a single file.

CSS and JavaScript minification

Stylesheets and scripts are minified and trimmed so browsers download and parse less on every page load.

CSS and JavaScript concatenation

Multiple stylesheets and scripts are merged into single files, cutting the number of HTTP requests a page has to make.

Runs in the background

Optimization jobs are queued and processed in batches behind the scenes, so a large media library never blocks the admin or the site.
