Core features
Automatic WordPress Image Optimization
Compress every new upload automatically or process images safely in the background. Keep your website fast without adding another maintenance task.
Lossy & Lossless Compression
Choose maximum file reduction or preserve every visual detail. Flexible quality profiles give you control over the perfect size-to-quality balance.
Convert Existing Media
Scan your existing Media Library and convert thousands of older images safely. Filter by format, attachment status, and file size before processing.
Safe Reference Migration
Update image URLs stored in posts, pages, custom post types, metadata, options, and supported custom tables. Built-in verification helps prevent broken image references.
WooCommerce & Builder Compatibility
Works with WooCommerce products, Gutenberg, Elementor, ACF image fields, galleries, and popular builders. Optimize images without disrupting existing layouts or content.
WebP & AVIF Conversion
Convert JPEG and PNG images to modern formats and automatically keep the smallest result. Larger converted files are rejected, so optimization never increases storage.
Intelligent Image Resizing
Set maximum width and height limits for oversized uploads. Images are resized only when necessary and work correctly with WordPress-generated scaled versions.
Complete Thumbnail Generation
Regenerate registered WordPress image sizes after conversion. Featured images, galleries, responsive images, and theme thumbnails continue working correctly.
Persistent Background Processing
Run large optimization and conversion jobs through native WP-Cron. Jobs continue after closing the browser, with progress, completion percentage, and estimated time remaining.

FAQ
Does Amazing Image Optimizer use an external image optimization service?
No. Amazing Image Optimizer processes images directly on your WordPress server. Your images are not sent to a third-party optimization service, and there are no external image-processing quotas from the plugin.
Can it optimize images that are already uploaded?
Yes. The plugin can scan your existing Media Library and process older images in the background. You can optimize, resize, and convert existing images instead of only handling new uploads.
Does it optimize new uploads automatically?
Yes. You can configure the plugin to optimize new image uploads automatically, so large images are compressed, resized, or converted before they slow down your site.
Does it support WebP and AVIF?
Yes. Amazing Image Optimizer can convert JPEG and PNG images to modern formats like WebP and AVIF. It also checks the result and avoids replacing an image with a larger converted file.
Will it break existing image links?
The plugin is designed to update image references safely when needed. It can update URLs stored in posts, pages, custom post types, metadata, options, and supported custom tables, with verification tools to help avoid broken references.
Can I control image quality?
Yes. You can choose between lossy and lossless compression and use quality settings to balance file size and visual quality.
Does it work with WooCommerce and page builders?
Yes. The plugin is built for WordPress media workflows and works with WooCommerce product images, Gutenberg, Elementor, ACF image fields, galleries, and common theme-generated image sizes.
Can it handle large media libraries?
Yes. Large jobs can run in the background using WP-Cron, with progress tracking, retries, pause/resume controls, and logging. Developers can also use WP-CLI commands for larger or more controlled optimization jobs.
Can I roll back changes?
The plugin includes safety tools and rollback protection for image processing jobs, helping you recover if an optimization task needs to be reversed or reviewed.
Are there monthly fees or per-image charges?
No. The plugin license is not based on how many images you optimize. Since processing happens on your own server, there are no plugin-level per-image charges or monthly optimization quotas.
