原文外掛簡介
MITS Image Optimizer is a professional image optimization toolkit for WordPress. It compresses images automatically on upload, batch-converts your entire media library to WebP and AVIF, configures Apache to serve next-gen formats automatically, and scans your site for common technical SEO issues.
Features
Auto-Compress on Upload
Every JPG/PNG above a configurable size threshold is automatically scaled and compressed before WordPress generates its thumbnail sizes. No extra steps needed.
Bulk Compression
Run a background batch job to compress all existing images in your media library. Progress is tracked and the job runs asynchronously – it won’t block your browser.
WebP Converter
Batch-convert all JPG/PNG/GIF files in your uploads directory to WebP format. Runs in the background using WP-Cron or a loopback HTTP request. Supports both Imagick and GD libraries.
AVIF Converter
Convert images to AVIF – the next-generation format that can be 30–50% smaller than WebP. Requires Imagick 7+ with AVIF support or PHP 8.1+ with GD imageavif(). The plugin detects support automatically and warns you if AVIF is unavailable on your server.
Apache .htaccess Configuration
One click adds mod_rewrite rules to your .htaccess so Apache automatically serves .webp files to browsers that support them, with no code changes required in your theme.
Image Dimensions Scanner
Detects images ≥ 1600 px wide that are used in posts or as featured images. Helps you find oversized images that slow down page loads, along with their file sizes, dimensions, and WebP/AVIF conversion status.
Site Audit
Scans your site for the most common technical issues: missing alt text, oversized images, missing SSL, outdated plugins, pages without Open Graph tags, and more. Results include actionable recommendations.
Dashboard Widget
A compact stats panel on the WordPress admin dashboard showing compression savings, WebP/AVIF conversion counts, and a link to the optimizer.
Requirements
PHP 8.0+, WordPress 6.0+
GD or Imagick PHP extension (for WebP/compression)
Imagick 7+ with AVIF or PHP 8.1+ GD (for AVIF conversion)
Apache + mod_rewrite (for automatic WebP serving via .htaccess)
