Nothing is uploaded to a CDN or an external optimization service, and there is no API key, account or paid tier. Your images never leave your host. * **Free.** The whole plugin, no upsell. * **Runs in the background.** A light scan estimates the work, then a background job (Action Scheduler) converts the library newest-to-oldest, one calendar month at a time. Pause, resume, cancel, close the tab – progress is durable. Optional email report when a run finishes. * **Or run it Fast.** An opt-in mode that drives the conversion from the open admin tab, so the server works continuously – much quicker on shared hosting with no cron. It throttles itself if the host pushes back, and stopping never loses work. * **Originals are untouched.** `foo.jpg` gets a `foo.jpg.webp` sibling; the source file is never modified. * **Serving** through a managed `.htaccess` block on Apache/LiteSpeed, with an to `` fallback on nginx or when `.htaccess` is not writable. * Per-attachment Convert / Reconvert / Remove buttons in the Media library. * New uploads are converted automatically, shortly after upload. The admin area is two screens under Media > Optimization: an **Optimization** page( scan prepare live monitor) and a separate **Settings** page (environment, conversion options, serving, notifications, cleanup). ## Screenshots [⌊Optimization: the prepare screen shows the whole-library image count, an estimated time, and a choice of Background or Fast run.⌉⌊Optimization: the prepare screen shows the whole-library image count, an estimated time, and a choice of Background or Fast run.⌉[ Optimization: the prepare screen shows the whole-library image count, an estimated time, and a choice of Background or Fast run.

Upload the `perxel-image-optimizer` folder to `/wp-content/plugins/`. 2. Activate the plugin through the Plugins screen. 3. Go to Media > Optimization. ## FAQ ### Does it modify my original images? No. Every converted file is written as a new `.webp` sibling next to the original. ### What happens on nginx? The `.htaccess` swap is Apache-only. On nginx the plugin rewrites `` tags to with a WebP source instead. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Perxel Image Optimizer” is open source software.

Fast mode self-pauses when the host throttles and resumes after an escalating cooldown; a live Gentle / Balanced / Turbo control sits on the running monitor. * Closing the tab, Stop, or Cancel never reverts converted files – the run parks and resumes from where it left off. * Per-attachment Convert / Reconvert / Remove buttons in the Media library, and automatic conversion of new uploads. * Serving via a managed `.htaccess` block on Apache/LiteSpeed, with an `` to fallback elsewhere. * Two admin screens under Media > Optimization – Optimization (prepare + live monitor) and Settings – in a shared sidebar layout, server-rendered. ## Meta * Version **1.0.1** * Last updated **2 days ago** * Active installations **Fewer than 10** * WordPress version ** 6.5 or higher ** * Tested up to **7.1.2** * PHP version ** 7.4 or higher ** * Tags * [convert to webp](https://wordpress.org/plugins/tags/convert-to-webp/)[image optimization](https://wordpress.org/plugins/tags/image-optimization/) [media library](https://wordpress.org/plugins/tags/media-library/)[webp](https://wordpress.org/plugins/tags/webp/) [webp images](https://wordpress.org/plugins/tags/webp-images/) * [Advanced View](https://wordpress.org/plugins/perxel-image-optimizer/advanced/) ## Ratings No reviews have been submitted yet.
