Pixellize

<p><strong>Pixellize Image Optimizer</strong> is a fast, lightweight, and beginner-friendly WordPress plugin that automatically converts uploaded images into modern WebP format.</p>
<p>It ensures that your website loads faster by replacing original image URLs across your entire site — including post content, image tags, and responsive srcset.</p>
<p>⚡ No manual conversion. No complex setup. Just upload and optimize.</p>
<h3>🔥 Key Features</h3>
<p>✅ Automatic WebP conversion on image upload<br />
✅ Bulk optimize images already in your library, with a live progress bar and background processing<br />
✅ Optimize a single page’s images on demand from the admin toolbar<br />
✅ Supports JPG, JPEG, PNG, BMP, and AVIF<br />
✅ Skips images already in WebP format<br />
✅ Smart fallback to Imagick if GD is unavailable<br />
✅ Adjustable WebP quality (0–100, default: 85)<br />
✅ Optional maximum image dimension to scale down large uploads before conversion<br />
✅ Replace image URLs in:</p>
<ul>
<li>Attachment tags</li>
<li>srcset (responsive images)</li>
<li>Post/page content</li>
</ul>
<p>✅ Keep originals and add WebP for every size, or replace and delete to save storage<br />
✅ Restore a single image back to its original from the Media Library<br />
✅ Keeps original file safe if conversion fails<br />
✅ Prevents duplicate conversions<br />
✅ Activation blocked if no supported library (GD/Imagick) is found</p>
