Description
  1. Upload the pixonix-local-image-optimizer folder to /wp-content/plugins/

  3. Go to Image Optimizer in the admin sidebar
  4. Configure your preferred quality settings
  5. Click Start Bulk Optimization to optimize existing images
Does this plugin require an API key?

No. All optimization happens locally on your server using GD or ImageMagick.

Will it slow down my uploads?

The optimization adds a small amount of processing time per image (typically under 1 second). For most sites, this is imperceptible.

Does it work with Nginx?

Image optimization works on any server. However, automatic WebP/AVIF serving via .htaccess requires Apache with mod_rewrite. For Nginx, you’ll need to add rewrite rules manually.

Can I re-optimize images?

Yes! Use the “Re-optimize All” button to clear optimization data and run bulk optimization again with new settings.

What happens when I uninstall?

All plugin data (settings and optimization metadata) is cleanly removed. Your original images and any generated WebP/AVIF files remain untouched.

Is it compatible with WooCommerce / Elementor / WoodMart?

Yes. Pixonix Local Image Optimizer works with all themes and page builders that use the standard WordPress media library.
