Akukita Image Optimizer & WebP Converter speeds up your WordPress site by automatically compressing every image you upload and creating a modern WebP copy — all done on your own server. Your media is never sent to an external service, so it stays private and you are never rate-limited or charged per image.
On top of optimisation, it does two things most image plugins don’t: it finds unused images sitting in your media library, and it catches uploads from form plugins (Gravity Forms, WPForms, Formidable) that normally bypass WordPress and never get optimised.
<h4>Why this plugin?</h4>
Large images are the number one cause of slow WordPress sites, and over time the media library fills up with images nobody uses any more. This plugin tackles both: it optimises new uploads the moment they arrive, and it shows you the clutter you can safely review and clean up.
<h4>Free features</h4>
<ul>
<li>Find unused images — scans your media library for images not referenced anywhere and lists them with their wasted disk space, so you can review what to remove. Detection is conservative and review-only; nothing is ever deleted automatically.</li>
<li>Form-plugin integrations — automatically optimises images uploaded through Gravity Forms, WPForms and Formidable Forms, which normally bypass the WordPress media flow and never get compressed.</li>
<li>Scan Uploads folder — finds JPEG/PNG images that exist on disk but were never optimised (placed there by migrations, FTP, or other plugins), and lets you optimise them all in one click.</li>
<li>Automatic compression on upload for JPEG and PNG, at a quality level you control.</li>
<li>WebP conversion — a <code>.webp</code> copy is generated for each image and its thumbnails.</li>
<li>Automatic WebP delivery — visitors whose browsers support WebP are served the smaller file automatically; everyone else gets the original.</li>
<li>EXIF / GPS metadata stripping for smaller files and better privacy.</li>
<li>100% local processing using your server’s Imagick or GD library. No accounts, no API keys, no per-image limits.</li>
<li>Savings dashboard showing how many images were optimised and how much space you saved.</li>
<li>Translation ready and fully internationalised.</li>
</ul>
<h4>Premium features</h4>
A separate Premium add-on unlocks:
<ul>
<li>Safe bulk deletion of unused images, with a backup so you can undo.</li>
<li>Bulk optimisation of your entire existing media library, processed in the background.</li>
<li>AVIF conversion for even smaller files than WebP.</li>
<li>Scheduled re-optimisation and per-folder rules.</li>
<li>One-click restore of original files.</li>
<li>Priority email support.</li>
</ul>
Premium is optional. The free plugin is fully functional on its own.
<h4>Privacy</h4>
This plugin does not send your images, or any personal data, to any external server. All optimisation happens on your hosting. It does not phone home and sets no cookies.
