plugopress

<p>PlugoSpeed is a WordPress performance plugin that combines <strong>page caching</strong>, asset optimization, and Core Web Vitals improvements in a single lightweight package.</p>
<p>It generates <strong>static HTML cache</strong> files served directly from disk via Apache — bypassing PHP and WordPress on cached requests. In testing on a standard VPS, this approach achieves sub-50ms TTFB and PageSpeed scores of 95/100 on desktop.</p>
<p>A React 18 dashboard provides real-time cache hit rates, bandwidth saved, and PageSpeed score tracking — no jQuery required.</p>
<h4>Core Features (Free)</h4>
<p><strong>Static HTML Cache</strong><br />
Pages are stored as static <code>.html</code> files on disk. Apache serves them directly — no PHP, no database, no WordPress bootstrap. Cache TTL is configurable (default: 24 hours).</p>
<p><strong>HTML Minification</strong><br />
Removes unnecessary whitespace and comments from the final HTML output, reducing page size without affecting content or functionality.</p>
<p><strong>CSS Minification</strong><br />
Minifies stylesheet files inline, reducing transfer size. Combine is intentionally disabled by default for HTTP/2 compatibility.</p>
<p><strong>JavaScript Defer</strong><br />
Adds <code>defer</code> to non-critical scripts, improving Time to Interactive (TTI) and Largest Contentful Paint (LCP) scores on mobile.</p>
<p><strong>Image Lazy Loading</strong><br />
Adds native <code>loading="lazy"</code> to images and iframes below the fold. Injects explicit <code>width</code> and <code>height</code> attributes to reduce Cumulative Layout Shift (CLS).</p>
<p><strong>Database Cleanup</strong><br />
Scheduled cleanup of post revisions, auto-drafts, spam comments, and expired transients. Configurable schedule: daily, weekly, or monthly.</p>
<p><strong>Cache Preloading</strong><br />
After purge, PlugoSpeed re-warms the cache automatically by walking your XML sitemap. Rate-limited to avoid server overload.</p>
<p><strong>Auto Cache Purge</strong><br />
Cache is invalidated on post save, theme change, plugin activation, and WooCommerce stock/price updates.</p>
<p><strong>PageSpeed Dashboard</strong><br />
Tracks your Google PageSpeed Insights score over time with a 30-day graph. Shows live cache hit/miss ratio, bandwidth saved, and page count.</p>
<h4>Pro Features</h4>
<p><strong>Remove Unused CSS (RUCSS)</strong><br />
Generates a per-page stylesheet containing only the CSS rules that are actually used. Eliminates render-blocking CSS from page builders and plugin stylesheets. Requires a PlugoPress API key.</p>
<p><strong>Critical CSS</strong><br />
Inlines the above-the-fold CSS directly in <code><head></code>, eliminating render-blocking for a faster LCP. Requires a PlugoPress API key.</p>
<p><strong>WebP Image Serving</strong><br />
Automatically serves <code>.webp</code> versions of images to supported browsers, reducing image payload by 25–35% without quality loss.</p>

</ul>
<h4>Convert to next-gen formats like AVIF and WebP</h4>
<p>With the TinyPNG WordPress plugin, you can easily convert your images to next-gen formats like AVIF and WebP. AVIF and WebP are modern image formats designed for the web. They are often smaller in size than older formats like JPEG and PNG, while keeping excellent image quality.</p>
<ul>
<li>WebP images are 25–34% smaller than JPEG (lossy) according to Google.</li>
<li>AVIF can reduce image size by up to 50% compared to JPEG, often even beating WebP in compression.</li>
</ul>
<p>Google’s PageSpeed Insights and other tools strongly recommend serving images in AVIF or WebP. Most modern browsers (like Chrome, Firefox, Edge, and Safari) now fully support WebP and AVIF. That means you can safely serve these formats to most of your visitors.</p>
<p>With the TinyPNG WordPress plugin, your images can be automatically converted to AVIF or WebP when you upload them. No extra steps are required.</p>
<h4>Optimizing all your images</h4>
<p>You can bulk optimize your existing JPEG, PNG, and WebP images all at once by going to Media > Bulk TinyPNG. Clicking on the big button will start compressing and converting, when needed, all unoptimized images in your media library.</p>
<p>If you have more images than your free credits allow, the tool will show you an estimated cost to optimize your entire library. If you are interested, you can upgrade your account to the paid plan and optimize the full library all in one go. Prefer to stay on the free plan? No problem! The bulk optimization tool will simply process images until your free limit is reached.</p>
<h4>Compress for performance</h4>
<p>The Tinify optimization engine is more than just compression. It is built to deliver the best image performance for the web, without sacrificing visual quality. Here’s how it helps:</p>
<ul>
<li>Display JPEG images more quickly with progressive JPEG encoding.</li>
<li>Color profiles are automatically translated to standard RGB color.</li>
<li>Convert CMYK to RGB to save more space and add compatibility.</li>
</ul>
<h4>Compatibility</h4>
<p>The TinyPNG plugin is fully compatible with <em>WordPress Multisite</em>. Next to this, TinyPNG for WordPress works smoothly with most themes and plugins. Here is a list of the popular plugins that have been tested to work smoothly with TinyPNG.</p>

<h4>Pricing</h4>
<p>You get 500 credits per month at no cost.</p>
<p>With a regular WordPress installation, you can compress roughly 100 images per month. Please note that converting images to AVIF or WebP uses an additional credit per image size. This means with the conversion feature enabled, you can roughly compress and convert 50 images per month for free.</p>
<p>The exact number depends on how many thumbnail sizes are generated by your theme or plugins. You can choose which of the generated thumbnail sizes should be optimized by going to Settings > TinyPNG page. You can upgrade to a paid plan to remove the limit and compress as many images as you like.</p>

TinyPNG – JPEG, PNG & WebP image compression

Great plugin allows you to speedup website using API from tinypng. Really useful, I don't have to minimize every image before uploading it to server.

Awesome


Original file size: 166kb



Tinypng compressed: 91kb



But it did not display the compressed image directly on the webpage






The file size after uploading has not been updated


Great plugin! Works as intended and hasn't failed me once in all these years! 


Great plugin


As a professional web developer, I found TinyPNG to be useful. I have recommended it to several customers who keep using it ever since. Fair use: for small blogs, the free version is fully functional, but limited to a certain number of images processed per month.


Useful image optimizer

Speed up your website. Optimize your JPEG, PNG, and WebP images automatically with TinyPNG.
