Webangon Image Optimizer
·
Clean unused images, regenerate thumbnails, and convert Media Library files to WebP or AVIF from one WordPress plugin.
Webangon Image Optimizer gives WordPress users one place to manage heavy image maintenance tasks. It helps reduce storage, improve image delivery, rebuild thumbnails after theme or migration changes, and run large jobs from WP-CLI.
Benefits for WordPress users:
- Find unused Media Library images with a safe dry scan before deletion.
- Protect images used in Elementor, post content, featured images, WooCommerce galleries, widgets, theme/plugin options, SEO fields, and more.
- Regenerate thumbnails after theme changes, imports, migrations, or image-size updates.
- Remove old generated thumbnail files while keeping original/main images.
- Convert images to WebP or AVIF for better performance.
- Rewrite image URLs across posts, post meta, Elementor data, and options after conversion.
- Run image cleanup, thumbnail, and conversion tasks from WP-CLI.
The admin screen is available under Media > Image Optimizer.

Recommended Workflow
- Take a full file and database backup.
- Run Image Cleaner in dry scan mode before deleting anything.
- Regenerate thumbnails after changing theme image sizes or after imports/migrations.
- Convert to WebP first for broad compatibility, or AVIF when the hosting stack supports it.
- Test important pages, Elementor templates, product galleries, and image-heavy pages after conversion.
