Tempaloo

The pricing problem with most WebP plugins
WordPress generates 5-8 thumbnails for every image you upload (<code>thumbnail</code>, <code>medium</code>, <code>medium_large</code>, <code>large</code>, <code>full</code>, plus theme-specific sizes). Most popular optimizers count each thumbnail as a separate credit, so a single product photo or blog hero can burn through 6-8 credits before you’ve touched your second image.
Tempaloo charges 1 credit per upload, no matter how many sizes WordPress derives from it. Same quota, 6-8x more usable conversions.
Concrete comparison — 1,000 uploads / month
<ul>
<li>ShortPixel / Imagify (per-thumbnail billing): 6,000 to 8,000 credits consumed → you need a 10k or 20k plan.</li>
<li>Tempaloo (per-upload billing): 1,000 credits consumed → our 5,000-image Starter plan covers you 5x over.</li>
</ul>
If your site averages 4+ thumbnails per upload (which it does, by default), Tempaloo is the lowest cost-per-converted-image on the market.
Built for
<ul>
<li>Agencies managing 10–100 client sites tired of credit math and license-per-site upcharges (our Growth plan covers 5 sites; Business covers unlimited).</li>
<li>WooCommerce stores with 50+ photos per product who blow through ShortPixel quotas in days.</li>
<li>Photographers, portfolios, magazines who want AVIF + high quality without the Imagify Pro tier.</li>
</ul>
What’s in version 1.0
<ul>
<li>Async upload pipeline — conversion runs in a fresh PHP process via non-blocking loopback, so your uploads finish instantly and we never fight other plugins on the same WordPress filter chain (security scanners, page builders, other optimizers). Most optimizers convert sync inline; that’s where conflicts come from.</li>
<li>Bulk converter with adaptive backoff, pause/resume, and live progress (current image, savings counter, ETA).</li>
<li>Diagnostic + reconcile tab — drift detection across filesystem, attachment metadata, bulk state, and retry queue. One click to repair desynchronized state. Most optimizers leave this to the user; we audit it.</li>
<li>AVIF on every paid tier — not a Pro-only add-on. Starter (5€/mo) already includes it.</li>
<li>WP-CLI — <code>wp tempaloo status / activate / bulk / restore / quota</code>. First-class deploy story for managed WordPress hosts.</li>
<li>Picture-tag and URL-rewrite delivery modes — picture-tag works with Gutenberg, Elementor, Bricks, Divi, Beaver Builder, WooCommerce, and any theme. URL rewrite stays out of your markup. CDN passthrough also supported.</li>
<li>Compatibility hardening — atomic temp+rename writes, explicit <code>nocache_headers()</code> + <code>DONOTCACHEPAGE</code> so LiteSpeed Cache, WP Rocket, and W3 Total Cache never serve stale admin data.</li>
<li>Developer hooks — three filters/actions to skip attachments, override quality, and react after conversion. See “Developer hooks” below.</li>
</ul>
Pricing
<ul>
<li>Free plan: 250 images / month, 1 site, no credit card required.</li>
<li>Starter (5 €/mo): 5,000 images/month, AVIF included.</li>
<li>Growth (12 €/mo): 25,000 images/month, 5 sites per license.</li>
<li>Business (29 €/mo): 150,000 images/month, unlimited sites.</li>
<li>Unlimited (59 €/mo): fair-use 500k/mo, priority SLA.</li>
</ul>
Paid plans include a 7-day trial and a 30-day money-back guarantee. Credits roll over up to 30 days on paid plans.

<h3>Privacy</h3>
See the External services section above for a full disclosure of the data this plugin sends to the Tempaloo API.
<h3>Developer hooks</h3>
Three hooks let you tailor the plugin’s behavior from your own theme or custom plugin. They fire on both the auto-convert-on-upload path and the bulk path (CLI or admin), so a single rule applies everywhere.
<pre><code>apply_filters( 'tempaloo_webp_skip_attachment', false, $attachment_id, $mode )
</code></pre>
Return <code>true</code> to bypass conversion for a specific attachment. Useful to exclude a folder, a CPT, or images larger than a threshold.
<pre><code>apply_filters( 'tempaloo_webp_quality_for', $quality, $attachment_id, $format )
</code></pre>
Override the quality value (1–100) per attachment. Returned values are clamped to 1–100. Useful to lift quality on portfolio shots or drop it on product thumbnails.
<pre><code>do_action( 'tempaloo_webp_after_convert', $attachment_id, $info )
</code></pre>
Fired after a successful conversion (one or more sizes written). <code>$info</code> contains <code>format</code>, <code>converted</code>, <code>failed</code>, <code>mode</code>, <code>quality</code>, <code>sizes</code>. Useful for CDN purges, custom logging, webhooks, manifest rebuilds.
Example — skip conversion for any attachment in the <code>private/</code> upload subfolder:
<pre><code>add_filter( 'tempaloo_webp_skip_attachment', function( $skip, $id ) {
 $path = get_attached_file( $id );
 return $path && false !== strpos( $path, '/uploads/private/' );
}, 10, 2 );<h3>Source code</h3>
</code></pre>
Tempaloo WebP is open source under the GPLv2 (or later) license. All compiled assets are generated from human-readable sources included in this distribution — no obfuscated or auto-generated code without a matching source.
<h4>Compiled assets</h4>
The admin dashboard UI is built with Vite + React + TailwindCSS. The compiled output (<code>build/admin.js</code> and <code>build/admin.css</code>) is generated from the source files under <code>admin-app/</code>:
<ul>
<li>TypeScript / TSX source: <code>admin-app/src/</code></li>
<li>Build configuration: <code>admin-app/vite.config.ts</code>, <code>admin-app/tsconfig.json</code>, <code>admin-app/tailwind.config.js</code>, <code>admin-app/postcss.config.js</code></li>
<li>Dependency manifest: <code>admin-app/package.json</code> (and <code>admin-app/package-lock.json</code> for reproducible installs)</li>
</ul>
<h4>How to rebuild</h4>
From the plugin root:
<pre><code>cd admin-app
npm install
npm run build
</code></pre>
This regenerates <code>build/admin.js</code> and <code>build/admin.css</code>. Output is deterministic — same source plus same lock file produce the same bytes.
<pre><code>npm run typecheck runs the TypeScript compiler in `--noEmit` mode for a standalone type check.
</code></pre>
<h4>Third-party libraries</h4>
All third-party libraries are pulled in via npm (declared in <code>admin-app/package.json</code>) — none are vendored as pre-built minified files in this repository. Their licenses are MIT and compatible with GPLv2-or-later.

Tempaloo WebP

The image optimizer that doesn't charge you for thumbnails. 1 credit per upload, all sizes included — 6-8x more conversions for the same quota.

Dropavif

DropAvif Image Optimizer, the comprehensive, all-in-one solution designed to modernize your WordPress media delivery instantly. We don’t just compress images; we transform your entire media stack into a high-performance engine that Google loves.
Unlike many popular plugins that limit you with small monthly quotas, rely on external cloud processing, or charge extra for basic features, <a href="https://dropavif.com/" rel="nofollow ugc">DropAvif.com</a> gives you full control through True Unlimited Local Optimization. Zero limits. Zero tokens. Zero hidden fees.
Everything is powered by our proprietary Quad-Engine — four independent, high-performance optimization processors working in parallel to deliver the fastest AVIF/WebP processing in the entire WordPress ecosystem. 
 It doesn’t matter whether you run: 
 a dynamic news portal with millions of monthly views, 
 a large WooCommerce store with 50,000 products, 
 a photography portfolio where quality and watermarking are absolute priorities, 
 an agency managing 50+ sites via WP-CLI, 
 or a massive eCommerce platform where every millisecond of load time translates into real revenue. 
DropAvif scales automatically — from your very first upload to your millionth pageview. Built for professionals, engineered for speed, and fully optimized for SEO.
<h3>🏆 WHY DROPAVIF IS THE NEW STANDARD (2025 and 2026 EDITION)</h3>
<h4>1. ⚡ The World’s First “Quad-Engine” Local Converter (FREE & UNLIMITED)</h4>
Stop relying on slow, outdated PHP conversion methods that time out your server. DropAvif introduces a revolutionary intelligent detection system that hunts for the fastest image processing tools available on your hosting environment.
We automatically prioritize speed and quality in this order: 
1. 🥇 Libvips (The Speed Demon): If available, we use this enterprise-grade library for memory-efficient, lightning-fast conversion. 
2. 🥈 Cwebp (Google CLI): Direct access to Google’s official binary for the highest possible WebP quality. 
3. 🥉 Imagick: A robust, high-fidelity fallback. 
4. running GD: Universal compatibility ensuring DropAvif works on 99.9% of servers.
The Result: You can convert thousands of images to WebP directly on your server, completely free, without timeouts, and without spending a single API credit.
<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. 
 /wp-content/uploads/ 
 /wp-content/themes/ (Optimize theme assets!) 
 /wp-content/plugins/ (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. 
 $ wp media-optimizer regenerate 
 $ wp media-optimizer regenerate –force</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>
