<p><strong>WebPressor</strong> is the fastest and most powerful WordPress image optimizer plugin for converting your existing JPEG and PNG media to next-generation <strong>WebP</strong> and <strong>AVIF</strong> formats — the two formats recommended by Google for achieving perfect Core Web Vitals and PageSpeed Insights scores.</p>
<p>WebP images are typically <strong>25–35% smaller</strong> than JPEG at the same quality. AVIF goes even further — delivering files up to <strong>50% smaller</strong> than JPEG and <strong>20% smaller</strong> than WebP. By serving these formats automatically to supported browsers, your site loads dramatically faster with zero manual effort.</p>
<p><strong>Version 2.0.0 is a major release</strong> introducing AVIF support, a redesigned dashboard, live optimization logs, server-level rewrite rules, system diagnostics, and much more.</p>
<h3>🚀 Why Image Optimization Matters</h3>
<p>Google’s Core Web Vitals (LCP, FID, CLS) are directly impacted by image delivery performance. Large, unoptimized images are the #1 cause of slow page loads and poor PageSpeed Insights scores. WebPressor solves this automatically by:</p>
<ul>
<li>Replacing heavy JPEG/PNG files with lightweight next-gen formats</li>
<li>Serving the smallest possible format each browser supports</li>
<li>Reducing total page weight by up to 50% with zero quality loss</li>
<li>Helping your site pass Google’s <strong>“Serve images in next-gen formats”</strong> audit</li>
</ul>
<h3>✨ Core Features</h3>
<p>🔹 <strong>WebP Conversion</strong> — Automatically convert all JPEG and PNG images to WebP format with GD library<br />
🔹 <strong>AVIF Conversion</strong> <em>(New in 2.0)</em> — Generate AVIF images for the smallest possible file sizes (PHP 8.1+ with GD AVIF support required)<br />
🔹 <strong>Bulk Optimizer</strong> — Process your entire Media Library in batches with a real-time live console log<br />
🔹 <strong>Auto-Convert on Upload</strong> — Instantly convert new images as they are added to the Media Library<br />
🔹 <strong>Smart Browser Detection</strong> — Serve AVIF to AVIF-capable browsers, WebP to WebP browsers, and original images to legacy browsers<br />
🔹 <strong>Two Delivery Methods</strong> — Choose between HTML URL replacement or server-level <code>.htaccess</code> rewrite rules<br />
🔹 <strong>Adjustable Quality Sliders</strong> — Independent WebP quality (0–100) and AVIF quality (0–100) controls<br />
🔹 <strong>Lossy & Lossless Modes</strong> — Select compression mode for each format<br />
🔹 <strong>Storage Savings Dashboard</strong> — See exactly how many megabytes and what percentage you have saved<br />
🔹 <strong>System Status Panel</strong> — Checks GD extension, WebP/AVIF availability, folder write permissions, and server type<br />
🔹 <strong>Nginx Configuration Helper</strong> — Displays a copyable Nginx server block for manual rewrite rule setup<br />
🔹 <strong>Non-Destructive</strong> — Your original JPEG/PNG images are always preserved and never overwritten<br />
🔹 <strong>Compatible With All Themes</strong> — Works with Elementor, Divi, Avada, GeneratePress, Astra, Kadence, OceanWP, and more<br />
🔹 <strong>WooCommerce Ready</strong> — Optimizes product images, gallery thumbnails, and all image sizes automatically<br />
🔹 <strong>Multisite Compatible</strong> — Works on WordPress Multisite installations<br />
🔹 <strong>Translation Ready</strong> — Fully localized with <code>.pot</code> file included</p>
<h3>📊 Performance Impact</h3>
<p>  Format<br />
  Savings vs JPEG<br />
  Browser Support</p>
<p>  WebP<br />
  25–35% smaller<br />
  97%+ of browsers</p>
<p>  AVIF<br />
  40–50% smaller<br />
  80%+ of modern browsers</p>
<h3>🛠️ How It Works</h3>
<ol>
<li><strong>Install & activate</strong> WebPressor from the WordPress dashboard</li>
<li>Go to the <strong>WebPressor <span aria-hidden="true" class="wp-exclude-emoji">→</span> Dashboard</strong> in the admin menu</li>
<li>Click <strong>Start Optimization</strong> to bulk-convert your existing Media Library</li>
<li>Watch the <strong>live console log</strong> as images are processed in real-time</li>
<li>Monitor your <strong>Storage Saved</strong> — the dashboard shows total bytes and percentage saved</li>
<li>New uploads are automatically converted in the background (if enabled in Settings)</li>
</ol>
<h3>⚙️ Delivery Methods</h3>
<p><strong>HTML Alteration (Default):</strong><br />
WebPressor replaces image <code>src</code> URLs in page HTML on-the-fly. Safe, requires no server configuration, and works on any shared hosting.</p>
<p><strong>Server Rewrite Rules (.htaccess):</strong><br />
For Apache and LiteSpeed servers, WebPressor writes redirect rules directly into <code>/wp-content/uploads/.htaccess</code>. Requests for <code>.jpg</code> and <code>.png</code> files are transparently redirected to their <code>.webp</code> or <code>.avif</code> equivalents — this also handles background CSS images, slider images, and images loaded via JavaScript.</p>

<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>

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.
