<p>Everything you need to optimize images and speed up your site.</p>
<p>Works out of the box with no complicated setup.</p>
<h3>Compress images without losing quality</h3>
<p>Reduce image file sizes automatically while keeping your images sharp and clear. Smush lets you compress images using both lossless and lossy compression, so you get the best balance of quality and performance without extra work.</p>
<p>You can also compress images outside the media library using Directory Smush, making it easy to optimize images stored in theme folders, plugins, or other directories on your server.</p>
<h3>Lazy load images for faster pages</h3>
<p>Enable image lazy load across your site so images load only when needed. This improves initial page speed and creates a smoother experience for visitors without extra configuration.</p>
<h3>Serve WebP and AVIF images automatically (PRO)</h3>
<p>Convert images to WebP and AVIF and serve them automatically to supported browsers. Smush helps you optimize images using next-gen formats to reduce file size and improve load times across your WordPress site.</p>
<h3>Deliver images faster with an Image CDN (PRO)</h3>
<p>Serve images through a global image CDN to reduce latency and improve load times for visitors around the world.</p>
<ul>
<li>119 global CDN servers</li>
<li>Up to 500 GB of bandwidth</li>
<li>Faster image delivery based on visitor location</li>
<li>Improved performance for image-heavy and high-traffic sites</li>
</ul>
<h3>Automatically resize and fix image dimensions (PRO)</h3>
<p>Eliminate common PageSpeed warnings and improve layout stability with automatic image sizing. Smush dynamically resizes images to perfectly fit their containers, regardless of original size, helping fix the “Properly size images” warning in Google PageSpeed Insights.</p>
<p>It also automatically adds missing width and height attributes to your images, improving rendering speed and reducing layout shifts. This helps you meet the “Ensure images have explicit width and height” recommendation without any manual work.</p>

Smush – Image Optimization, Compression, Lazy Load, WebP & CDN

Thank you for taking over half of the WordPress dashboard with your giant ad. It motivated me to remove your plugin and install EWWW Image Optimizer instead.

Huge black friday Ad. Stop advertising on my dashboard.


Unfortunately, it does not support WordPress Multisite and Arabic Language.

<p><strong>Effortless Simple Image Optimiser</strong> hooks directly into the WordPress Media Library upload pipeline and compresses, resizes and (optionally) converts images the moment they are uploaded — all using the built-in PHP GD extension.</p>
<h4>Features</h4>
<ul>
<li><strong>JPEG compression</strong> — re-encodes JPEGs at a configurable quality level (default: 82). GD strips EXIF metadata automatically, further reducing file size.</li>
<li><strong>PNG compression</strong> — applies lossless GD compression to PNG files.</li>
<li><strong>PNG <span aria-hidden="true" class="wp-exclude-emoji">→</span> JPEG conversion</strong> — converts opaque (non-transparent) PNGs to JPEG for significant space savings. Transparent PNGs are always kept as PNG.</li>
<li><strong>Image resizing</strong> — scales down images that exceed a configurable maximum width or height while maintaining the original aspect ratio.</li>
<li><strong>WebP generation</strong> — optionally saves a <code>.webp</code> sidecar file alongside every optimised image (requires GD compiled with WebP support).</li>
<li><strong>Zero external dependencies</strong> — no API keys, no third-party services, no composer packages.</li>
<li><strong>Graceful degradation</strong> — if GD is not available the plugin skips processing and logs a notice; uploads are never blocked.</li>
</ul>
<h4>Settings</h4>
<p>Navigate to <strong>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Image Optimiser</strong> to configure:</p>
<ul>
<li>Enable / disable automatic optimisation on upload</li>
<li>JPEG quality (1–100, default 82)</li>
<li>Enable PNG <span aria-hidden="true" class="wp-exclude-emoji">→</span> JPEG conversion</li>
<li>Enable WebP sidecar generation + WebP quality</li>
<li>Enable / disable resizing</li>
<li>Maximum width in pixels (default 1920)</li>
<li>Maximum height in pixels (default 1920)</li>
</ul>
<h4>Requirements</h4>
<ul>
<li>PHP 7.4 or higher</li>
<li>PHP GD extension (enabled on virtually all shared hosting)</li>
<li>WordPress 5.9 or higher</li>
</ul>
