Plus WebP or AVIF

It is very useful to replace the URLs of images of existing content as well.

Easy and very useful


I really like this plugin and it's very good in other aspects. However, on both of my websites, when converting in bulk, I was unable to continue the conversion for a certain period of time, indicating an Ajax 500 error. What is the reason?


500 error


This is great plugin to save my server space!



Dear developer, I prefer to donate by paypal, usdt or stripe instead of inputting my credit card elsewhere.


Great plugin

Dropavif

DropAvif Image Optimizer is not just a compression tool—it is a complete image delivery platform for WordPress.
We solve the modern web’s biggest challenge: balancing visual quality with lightning-fast load times. Unlike legacy plugins that struggle with server limits, DropAvif offloads 100% of the processing work to our dedicated optimization cloud.
Whether you are a photographer protecting your work with watermarks, an agency managing 50 sites via WP-CLI, or an eCommerce giant needing instant product page loads, DropAvif is built for you.
<h3>💡 Why DropAvif is the Superior Choice in 2025</h3>
<h4>🧠 Exclusive “Smart Format Selection” Technology</h4>
Stop guessing between WebP and AVIF. Our cloud engine generates both next-gen formats, analyzes them in real-time against the original, and automatically serves the absolute smallest file to your visitor. 
* Result: You get the extreme compression of AVIF where it shines, and the efficiency of WebP where it’s better. You never leave performance gains on the table.
<h4>☁️ Zero-Load Cloud Architecture</h4>
Traditional plugins use your server’s CPU (GD/Imagick) to compress images. This causes timeouts, failed uploads, and slows down your dashboard. 
DropAvif is different. We send your images to our powerful API. Your server stays fast, and we handle the heavy lifting. 
* Process 50,000+ images in the background without slowing down your site. 
* No timeouts on shared hosting. 
* Resume capability automatically handles interruptions.
<h4>👁️ Perceptual “Smart Optimization” (AI)</h4>
Our flagship compression engine uses perceptual analysis (SSIM) to understand what the human eye actually sees. It intelligently removes invisible data while preserving critical edges, textures, and colors. 
* Result: Images are up to 80% lighter than originals but look virtually identical.
<h3>🛡️ Professional Image Protection: Watermarking</h3>
Protect your intellectual property automatically without touching your original files. 
* Non-Destructive: The watermark is applied only to the optimized WebP and AVIF versions served to visitors. Your original source file remains clean and safe. 
* Cloud-Powered: Watermarking happens in the cloud during conversion, ensuring perfect quality and transparency handling. 
* Flexible Control: Position the watermark anywhere (9 anchor points), adjust opacity, scale, and padding.
<h3>📸 Comprehensive Image Features</h3>
Next-Generation Format Conversion 
* AVIF Conversion: The future of images. Offers superior compression (often 50% smaller than WebP) and HDR color support. 
* WebP Conversion: The modern standard. Fully supported by all browsers. 
* Automatic Fallbacks: We use advanced server rules (.htaccess / Nginx). If a browser doesn’t support AVIF, we serve WebP. If it doesn’t support WebP, we serve the original. Zero broken images.
Massive Bulk Optimization 
* Asynchronous Engine: Optimize your entire library in the background. You can close the browser tab and let DropAvif work its magic. 
* Directory Scanning: DropAvif optimizes everything, not just the Media Library. 
 * <code>/wp-content/uploads/</code> 
 * <code>/wp-content/themes/</code> (Optimize theme assets!) 
 * <code>/wp-content/plugins/</code> (Optimize images from other plugins!) 
 * Any custom folder you define.
Before & After Comparison 
* Visual Proof: Use our built-in comparison tool in the Media Library to see the quality difference and file size savings for any specific image side-by-side.
<h3>⚡ Core Web Vitals & Performance Suite</h3>
It’s not just about file size—it’s about how the browser loads the page.
Advanced Lazy Loading 
* Smart Loading: Only load images, iframes, and videos when they enter the viewport. 
* Native Support: Utilizes browser-native lazy loading attributes for maximum performance. 
* Video Placeholders: Replaces heavy YouTube/Vimeo iframes with a lightweight preview image. The video resource only loads when the user clicks “Play.”
Critical Image Preloading (LCP) 
* LCP Optimization: Automatically identifies and preloads the Largest Contentful Paint (LCP) image (usually the hero banner) to instantly boost your Google Lighthouse score.
Layout Shift (CLS) Fixes 
* Missing Dimensions: Automatically scans your HTML and adds missing <code>width</code> and <code>height</code> attributes to <code><img></code> tags to prevent content jumping as images load.
<h3>🔌 Deep Ecosystem Integration</h3>
DropAvif is engineered to work seamlessly with the tools you already use.
Smart SEO Sitemaps 
* Yoast SEO & Rank Math: We automatically update the image URLs in your XML sitemaps. This ensures Google bots index your optimized WebP/AVIF versions instead of the heavy originals, boosting your SEO rankings.
Page Builders & Galleries 
* Full Compatibility: Automatically detects and optimizes images added by Elementor, WPBakery, Divi, Beaver Builder, and Gutenberg. 
* Gallery Support: Native support for NextGen Gallery, Modula, and FooGallery.
eCommerce Ready 
* WooCommerce: Optimize thousands of product variations without slowing down the checkout flow.
CDN Support 
* Cloudflare API: Connect your Cloudflare account directly. The plugin will automatically purge the Cloudflare cache for specific images whenever they are optimized, ensuring users always see the latest version.
<h3>💻 Full WP-CLI Integration (For Developers)</h3>
Manage optimization entirely from the command line. Perfect for agencies, cron jobs, and automated deployment pipelines.
<ul>
<li>Regenerate: Run bulk conversions or force re-optimization.
<ul>
<li><code>$ wp media-optimizer regenerate</code></li>
<li><code>$ wp media-optimizer regenerate --force</code></li>
</ul>
</li>
<li>Automate: Script the optimization process across multiple sites without ever logging into the WordPress dashboard.</li>
</ul>
<h3>🔧 Advanced Control for Agencies</h3>
Role-Based Upload Policies 
Stop clients or editors from uploading massive, unoptimized photos that kill your server storage. 
* Set Max File Size (e.g., 5MB) limits per user role. 
* Set Max Image Dimensions (e.g., 2000px width) limits per user role.
Granular Exclusions 
Complete control over what gets optimized. Exclude by: 
* Path/URL: e.g., <code>/sensitive-documents/</code> 
* Filename Pattern: e.g., <code>banner-hq-*.jpg</code> 
* Thumbnail Size: Keep your full-resolution originals untouched while optimizing only the thumbnails.
<h3>🛡️ Safety, Backup & Privacy</h3>
<ul>
<li>Originals are Read-Only: We never overwrite your original files. We create optimized copies in a separate folder.</li>
<li>One-Click Restore: Don’t like the result? Revert to the original image instantly.</li>
<li>Backup Friendly: Option to exclude the <code>media-optimizer-files</code> directory from backup plugins (UpdraftPlus, etc.) to save massive amounts of backup storage space (since optimized files can always be regenerated).</li>
</ul>
<h3>💸 Pricing Model</h3>
