Manly WebP Converter converting images to the modern WebP format. For example, a shop with 1,000 products can see overall storage drop from around 15 GB to 6 GB. Page load times are reduced proportionally.
Features: 
– Convert images for one WooCommerce product or all media images. 
– Keep originals during testing or delete originals after conversion. 
– Updates attachment metadata and content references in posts, pages, and all other post types. 
– Shows progress, logs, and total bytes saved. 
– Adjustable WebP image quality — test on a single page or product first and verify picture quality visually before converting your entire library. 
– Conversion of thousands of pictures may take hours; you can stop at any time by clicking the Stop button and resume later by clicking Start again — already-converted images are skipped automatically. Refreshing or closing the page is also safe: each image is saved to disk as it is processed, so starting again after a page refresh will continue from where the conversion left off.
<h4>Requirements</h4>
This plugin requires the PHP GD extension, which is usually included with standard PHP installations. If GD is not already active on your server, it can be enabled in cPanel → PHP Configuration with a single tick.
<h4>Conversion Modes</h4>
Both modes convert attachments stored in the media library. The difference is scope:
<ul>
<li>Single Product — reads the featured image and gallery post meta of the chosen WooCommerce product and converts only those linked attachments.</li>
<li>All Images — queries every JPEG, PNG, and GIF attachment in the entire media library, regardless of whether it is attached to a product.</li>
</ul>
After each conversion, the plugin searches <code>post_content</code> and <code>post_excerpt</code> across every post type (posts, pages, products, custom post types) and rewrites both full URLs and path-only references. It does not update image URLs stored in post meta or custom fields (e.g. page-builder block attributes saved outside the content column).
WooCommerce product images are safe because featured images and gallery images are stored as attachment IDs, not URLs — WordPress resolves them dynamically from the updated attachment record.
Warning: page builders and URL-based custom fields. Tools such as Elementor, Divi, Beaver Builder, and ACF (when set to return a URL) store image URLs directly in post meta. These are not rewritten by this plugin. If you then delete the original files, any such stale URL will point to a missing file and cause broken images on the front end.
Recommended workflow: 
1. Run the conversion with Keep Originals enabled. 
2. Check your site visually — especially pages built with a page builder. 
3. Only disable Keep Originals (to delete originals) once you are confident no post meta or theme option holds a raw image URL that has not been updated.
<h3>Additional Information</h3>
This plugin is primarily designed for WooCommerce stores. While the All Images mode covers the entire media library, the core workflow and Single Product mode are built around WooCommerce product images. More detailed guidance will be added in a future update.

PuffPix Compress automatically optimizes every image you upload to WordPress — reducing file sizes by 40–80% without visible quality loss. Faster pages, lower bandwidth, better Core Web Vitals scores.
It works by connecting to the <a href="https://puffpix.com" rel="nofollow ugc">PuffPix</a> image compression API. When you upload an image, PuffPix compresses it server-side using industry-leading encoders (mozjpeg, pngquant, cwebp) and returns the optimized file, which replaces the original in your media library.
<h4>Why PuffPix?</h4>
<ul>
<li>No server load — compression happens on PuffPix servers, not yours</li>
<li>Better results than GD — uses mozjpeg and pngquant for noticeably smaller files at the same quality</li>
<li>All thumbnail sizes — automatically compresses every generated thumbnail, not just the original</li>
<li>EXIF stripping — removes GPS coordinates and device metadata for privacy</li>
<li>Bulk optimization — compress your entire existing media library in one click with a live progress log</li>
<li>Per-image stats — see exactly how much each image was reduced, right in the media library</li>
</ul>
<h4>Compression Engines</h4>
<ul>
<li>Standard (GD) — PHP’s built-in image library. Fast and universally compatible. Quality 85 (balanced) or 72 (aggressive).</li>
<li>Pro (mozjpeg + pngquant) — significantly better compression than GD at the same visual quality. JPEGs typically 20–30% smaller than GD output.</li>
<li>Max — maximum compression using the best available encoder per format. Smallest possible file size. Requires Pro or Trial plan.</li>
</ul>
<h4>Supported Formats</h4>
JPEG, PNG, WebP, GIF. SVG support is available on the PuffPix web tool.
