Deactivate the WordPress default image compression which got introduced with <a href="https://developer.wordpress.org/reference/hooks/jpeg_quality/" rel="nofollow ugc">WordPress 2.5</a>.
<h3>Purpose</h3>
By default, WordPress compress every uploaded image by 90%. In combination with other image optimisation tools, this can lead to pixelated images. This plugin deactivates the default image compression to avoid this issue.

PixelCraft with WebP helps speed up your site by creating WebP copies of images you upload (and optionally replacing originals). It uses WordPress image APIs (GD or Imagick) with sensible PHP fallbacks when a host mis-reports WebP support.
<ul>
<li>Automatic conversion on upload for JPEG and PNG (after WordPress generates thumbnails).</li>
<li>Keep originals or replace them after a successful WebP write (your choice).</li>
<li>Quality preset and max width/height for the full-size WebP.</li>
<li>Bulk conversion in the admin (batched AJAX, optional WP-Cron background queue).</li>
<li>Savings report per attachment (stored in attachment meta).</li>
<li>Settings under Settings → PixelCraft with WebP.</li>
<li>Media list column showing optimization status.</li>
<li>Frontend delivery: when enabled, image URLs can switch to <code>.webp</code> for clients that send <code>Accept: image/webp</code> (compatible with WooCommerce product images that use core attachment APIs).</li>
<li>No external services — conversion runs on your server only.</li>
</ul>
