Anek Image Optimizer is a professional-grade image optimization plugin built for speed, privacy, and flexibility. It is 100% free, runs entirely on your own server, and ships with zero telemetry \u2014 your images never leave your infrastructure.<\/p>\n\n
Most optimization plugins lock you into a single backend. Anek supports three simultaneously:<\/p>\n\n
.htaccess<\/code> rules and Nginx config snippets for zero-PHP server-level delivery \u2014 browsers that support AVIF or WebP get them automatically; others fall back gracefully.<\/li>\n<\/ul>\n\nDeep WordPress Integration<\/h4>\n\n\n- Optimize directly from the Media Library<\/strong> \u2014 per-image buttons appear in attachment details.<\/li>\n
- Bulk optimization<\/strong> \u2014 compress your entire media library in one click with real-time progress.<\/li>\n
- Auto-optimize on upload<\/strong> \u2014 new images are processed the moment they are added.<\/li>\n
- File-system deep scanner<\/strong> \u2014 discovers and optimizes images outside
wp-content\/uploads<\/code>, including theme images, plugin assets, and custom directories.<\/li>\n<\/ul>\n\nPreserve Originals<\/h4>\n\n
Toggle on \"Preserve Originals\" and a backup copy of every image is kept before compression. Restore any image to its original state at any time with zero data loss.<\/p>\n\n
Quality & Exclusion Controls<\/h4>\n\n\n- Adjustable quality slider (0\u2013100) per compression run.<\/li>\n
- Strip EXIF metadata to reduce file size further.<\/li>\n
- Set a minimum file size threshold to skip images already small enough.<\/li>\n
- Exclude specific paths from bulk operations.<\/li>\n<\/ul>\n\n
100% Free, Zero Telemetry, Fully Self-Hosted<\/h4>\n\n\n- No data leaves your server.<\/strong> All processing happens locally.<\/li>\n
- Zero telemetry<\/strong> \u2014 no usage tracking, no analytics, no phone-home requests.<\/li>\n
- No API keys, no accounts, no subscriptions.<\/strong><\/li>\n
- Full feature set available from day one with no freemium locks or upsells.<\/li>\n<\/ul>\n\n\n
\n- Upload the
anek-image-optimizer<\/code> folder to the \/wp-content\/plugins\/<\/code> directory.<\/li>\n- Activate the plugin through the 'Plugins' menu in WordPress.<\/li>\n
- Navigate to Anek Image Optimizer<\/strong> in the admin sidebar to configure your settings.<\/li>\n
- (Optional) Install Libvips on your server for maximum performance.<\/li>\n<\/ol>\n\n\n
\nWhat is Libvips and why does it matter?<\/h3><\/dt>\nLibvips is a low-memory, high-speed image processing library used by major image CDNs like Cloudinary. It is significantly faster than GD or Imagick, especially for large images or bulk operations. The plugin auto-detects whether Libvips is available on your server.<\/p><\/dd>\n
Does this plugin support AVIF?<\/h3><\/dt>\nYes. AVIF output is supported via Libvips (fastest), Imagick (if compiled with AVIF support), or Spatie\/Intervention with an Imagick driver. The server environment tab shows exactly which formats your server can produce.<\/p><\/dd>\n
Does my server need Libvips?<\/h3><\/dt>\nNo. Libvips is optional. If it is not available, the plugin falls back to Spatie Image or Intervention Image with GD or Imagick, both of which are standard on most WordPress hosting.<\/p><\/dd>\n
Are my original images safe?<\/h3><\/dt>\nYes. Enable \"Preserve Originals\" in the settings and every original is backed up before any compression is applied. You can restore individual images at any time.<\/p><\/dd>\n
Does this plugin send images to a third-party service?<\/h3><\/dt>\nNo. All optimization is performed locally on your server. No images, metadata, or usage data is ever transmitted externally.<\/p><\/dd>\n
Can I test which library produces the best results for my images?<\/h3><\/dt>\nYes. The Lab Testing tab lets you upload any image and run it through all available libraries simultaneously, showing you the compressed file size, savings percentage, processing time, and a preview for each result.<\/p><\/dd>\n\n<\/dl>\n\n\n
