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.

Kitgenix

<p><strong>Kitgenix Image Optimizer</strong> compresses and resizes images automatically on upload and provides bulk optimization tools for your existing media library — all powered by WordPress’s native WP_Image_Editor (GD or Imagick). No external API required.</p>
<p>Designed to be lightweight and modular:<br />
– Automatic optimization on upload<br />
– Configurable JPEG, WebP, and PNG quality settings<br />
– Max-dimension resizing (preserves aspect ratio)<br />
– Optional WebP conversion<br />
– Optional EXIF metadata stripping<br />
– Optional thumbnail sub-size optimization<br />
– Per-image status tracking with a dedicated Images tab<br />
– Activity log for all optimization events<br />
– Bulk optimization with start/stop controls</p>
<h4>Features</h4>
<ul>
<li><strong>Zero external dependencies</strong> — uses WordPress’s built-in WP_Image_Editor powered by GD or Imagick.</li>
<li><strong>Auto-optimize on upload</strong> — every new image is compressed and resized the moment it enters the media library.</li>
<li><strong>Configurable quality</strong> — set JPEG quality (1–100), WebP quality (1–100), and PNG compression level (0–9) independently.</li>
<li><strong>Max dimension capping</strong> — set maximum width and height; images exceeding those dimensions are scaled down while preserving aspect ratio.</li>
<li><strong>WebP conversion</strong> — optionally convert JPEG and PNG images to WebP on upload.</li>
<li><strong>Metadata stripping</strong> — remove EXIF data to shave extra bytes off every image.</li>
<li><strong>Thumbnail optimization</strong> — optionally optimize every registered sub-size alongside the full image.</li>
<li><strong>Bulk optimization</strong> — the Images tab shows your 30 most recent uploads with per-image status and a bulk start/stop control that processes one image at a time without timeouts.</li>
<li><strong>Activity log</strong> — the Log tab records every optimization and settings change with timestamps.</li>
</ul>
<h3>Quick Start</h3>
<ol>
<li>Install and activate the plugin.</li>
<li>Go to Kitgenix <span aria-hidden="true" class="wp-exclude-emoji">→</span> Image Optimizer to configure settings.</li>
<li>Upload an image — it will be optimized automatically if “Optimize on Upload” is enabled.</li>
<li>Use the Images tab to bulk-optimize existing media.</li>
</ol>
