原文外掛簡介
Webxperthub Media Optimizer optimizes your WordPress media library without slowing down your site or your server. It automatically compresses new uploads and converts them to WebP, and lets you bulk-process your entire existing media library safely in the background.
Key Features
Automatic optimization on upload — no manual steps required
Converts images to WebP (or PNG, or compress-only with original format kept)
Typically reduces file size by 40-60% with no noticeable quality loss
Background queue processing — bulk-optimize thousands of images without server timeouts
Optional resizing of oversized uploads to a configurable maximum width/height
Keeps a backup of your original files by default
Fully multisite compatible
Uses your server’s native Imagick or GD library — no external API, no data ever leaves your server
Developer-friendly filter hooks for custom workflows
How It Works
When Webxperthub Media Optimizer is enabled, every new image uploaded to your Media Library is automatically queued for optimization. A background process (WP-Cron) picks up queued images in small batches, so your server is never overloaded even if hundreds of images are queued at once.
Use the Bulk Optimize screen under Webxperthub Media Optimizer in your admin menu to queue your entire existing media library and watch a live progress bar as images are processed.
For Developers
Skip optimization for specific attachments:
add_filter( 'mopw_skip_optimization', function( $skip, $attachment_id ) {
if ( get_post_meta( $attachment_id, '_never_optimize', true ) ) {
return true;
}
return $skip;
}, 10, 2 );
Override format/quality for specific attachments:
add_filter( 'mopw_before_optimize_args', function( $args, $attachment_id ) {
if ( has_term( 'print-quality', 'category', $attachment_id ) ) {
$args['quality'] = 95;
}
return $args;
}, 10, 2 );
Run custom logic after an image is optimized:
add_action( 'mopw_after_optimize', function( $attachment_id, $original_size, $new_size ) {
error_log( "Attachment {$attachment_id} shrank from {$original_size} to {$new_size} bytes." );
}, 10, 3 );
