<p><strong>Petro SEO Images to WebP</strong> converts your existing JPEG and PNG attachments to WebP in bulk, then serves them on the front-end through the standard <code><picture></code> element with a full responsive <code>srcset</code>. The original files stay untouched on disk, so reverting is as simple as flipping a switch.</p>
<p>Designed to be small, dependency-free and predictable. No external services, no images uploaded anywhere, no opaque queue.</p>
<h4>What it does</h4>
<ul>
<li>Converts every registered image size (full + thumbnails) to <code>.webp</code> next to the original (e.g. <code>photo.jpg</code> <span aria-hidden="true" class="wp-exclude-emoji">→</span> <code>photo.jpg.webp</code>).</li>
<li>Wraps <code><img></code> tags from <code>wp_get_attachment_image()</code> and <code>the_content</code> in <code><picture><source type="image/webp">…</picture></code>, preserving full <code>srcset</code> and <code>sizes</code>.</li>
<li>Skips images automatically if a previous run failed because of filesystem permissions, so you can retry on demand without reprocessing the whole library.</li>
<li>Ramps the WebP quality down (75 <span aria-hidden="true" class="wp-exclude-emoji">→</span> 60 <span aria-hidden="true" class="wp-exclude-emoji">→</span> 45 <span aria-hidden="true" class="wp-exclude-emoji">→</span> 40) when the encoded file ends up larger than the original, so you never ship a “WebP” that is heavier than the JPEG.</li>
<li>Idempotent: re-running the bulk job only touches new or updated images.</li>
</ul>
<h4>What it does NOT do</h4>
<ul>
<li>It does not delete or modify your original JPG/PNG files.</li>
<li>It does not require Imagick or a specific image library beyond what WordPress already uses (<code>wp_get_image_editor()</code>).</li>
<li>It does not phone home, register endpoints, or load remote scripts.</li>
</ul>
<h4>Privacy</h4>
<p>The plugin processes images locally using WordPress’s built-in image editor. No data is sent to third-party services.</p>


Petro SEO Images to WebP

² Your theme needs to support this too.</p>
<h4>Gallery shortcode</h4>
<p>Of course you can use “exclude” and “include” parameters in your [gallery] shortcode like you already know from the traditional gallery shortcode. The Gallery Manager plugin does not touch the mechanic of the default [gallery] shortcode.</p>
<h4>Settings</h4>
<p>You can find the settings page in your Dashboard -> Settings -> Galleries.</p>
<h4>Template files</h4>
<p>All plugin outputs can be changed via user defined HTML templates. Just put the templates you want to overwrite inside your theme folder (no matter if parent theme or child theme). You can find the default templates in the plugin folder in “templates/”. You can find a list of the available template files in documentation of the pro version. <em>Please do not modify the original templates! You would lose all your modifications when updating the plugin!</em></p>
<h4>Questions and support requests</h4>
<p>Please use the support forum on WordPress.org only for this free lite version of the plugin. For the pro version there is a separate support package available. <em>Please do not use the WordPress.org support forum for questions about the pro version</em> or questions about my services! Of course you can hire me for consulting, support, programming and customizations at any time.</p>
<h4>Pro Version</h4>
<p>Gallery Manager is available as <a href="https://dennishoppe.de/en/wordpress-plugins/gallery-manager" rel="nofollow ugc">premium version</a> too. In the premium version you can use all options and features which are restricted in the lite version.</p>
<p>Possibly even more important, buying the premium edition gives you access to me and my support team. You can email us your questions about usage of the plugin or your problems in setting it up and we will assist you in no time!</p>

Gallery Manager

We integrated the pro version for a client project and needed to show custom content (coypright info) to the lightbox and the image galleries.

Our support requests were answered pretty quickly with some helpful advice as well as an updated plugin code (incorporated new filter hook) in order to enable us implementing our customer requests without code hacks.

Recommended all-in-one plugin solution for galleries so far!

Nice plugin & reliable support

Supercharged image gallery management tool with touch-enabled, responsive, mobile-friendly image lightbox for WordPress!
