External pricing, checkout, licensing, account, and update services are documented below. ### External services This plugin processes images locally on your WordPress server. It connects to external services only for admin pricing, checkout, licensing, account management, and software- update services described here. AdminPlugins pricing API The plugin can contact the AdminPlugins pricing API to load public plan prices, license limits, discount state, and checkout URLs shown on the Upgrade / pricing page. No pricing request is made until an administrator explicitly enables price loading on that page. Enable and Disable work through AJAX without reloading the page. While enabled, a server-side HTTP GET request is made only when no valid 24- hour local pricing cache exists. Disabling price loading removes the consent setting and the local pricing cache. The request uses `https://adminplugins.com/wp-json/ awo-freemius/v1/pricing` and may use `https://adminplugins.com/?rest_route=/awo- freemius/v1/pricing` as a fallback. It includes `source=plugin`, the plugin version in the User-Agent, and normal server-to-server HTTP connection information such as the server IP address. No image files, Media Library contents, conversion settings, users, passwords, license keys, or site URL are deliberately sent by these pricing requests. Service provider: AdminPlugins. Terms: https://adminplugins.com/terms-and-conditions/ Privacy: https://adminplugins.com/privacy-policy/ Freemius SDK and Checkout The plugin uses the Freemius SDK for optional Pro licensing, account management, software updates, and checkout. The Freemius Checkout JavaScript from `https://checkout. freemius.com/js/v1/` is loaded only after an administrator clicks an Upgrade button. If the checkout script cannot load, the administrator is sent to the normal secure Freemius checkout URL. Freemius may receive licensing and site/account data when an administrator opts in, activates or manages a license, opens Freemius account/ license screens, checks for updates, or starts checkout. Checkout data can include product ID, plan ID, pricing ID, selected license quantity, billing cycle, currency, active coupon code when supplied by the pricing API, and license key when upgrading an existing license.

Upload the plugin folder to /wp-content/plugins/. 2. Activate the plugin through the Plugins screen. 3. Go to WebP Optimizer in the WordPress admin menu. 4. Check the server status and start conversion. ## FAQ ### Does this replace my original images? No. Original JPG and PNG files are kept. Native WebP uploads are treated as already optimized sources, and generated WebP files are created next to JPG/PNG originals. ### Does this use an external API? Image conversion runs locally on your own server using Imagick or GD. The admin Upgrade / pricing and licensing screens can connect to the external services documented below. ### Is there an image limit? No plugin-side image count limit is applied. Images are processed in safe batches to avoid server timeouts. ### What file structure does it use? The plugin creates files like image.jpg.webp and image.png.webp. Native WebP uploads are not converted into image.webp.webp. ## Reviews ![](https://secure.gravatar.com/avatar/a54a6aed2e2800e48994ec703107b08f6366511e3bdef1957158c0e070c23239? s=60&d=retro&r=g) ### 󠀁[Excellent and very simple](https://wordpress.org/support/topic/excellent-and-very-simple-4/)󠁿 [Levis](https://profiles.wordpress.org/levismodding/) July 26, 2026 A solid and well-designed image optimization plugin with clear controls, useful diagnostics, and reliable background processing. Everything runs locally on the server without external APIs, cloud uploads, credits, or image limits. The interface is easy to understand, and the detailed reports make it simple to see what was processed, what still needs attention, and how much space was saved.
