Description
WebPioneer is a compatibility-first WebP conversion workflow for WordPress sites that want local processing, delivery safety, and clear operational visibility without aggressive automation.
Instead of acting like a generic image optimization suite, WebPioneer focuses on the WebP workflow that already exists inside your WordPress media library: upload-time conversion, bulk conversion, folder-based filtering, media inspection, and explicit serving controls.
The plugin is designed for site owners and agencies that want to generate WebP locally, inspect results, and roll out delivery changes conservatively.
Features:
– Converts JPG, PNG, and non-animated GIF to WebP.
– Skips animated GIF safely.
– Converts on upload and supports bulk conversion for existing media.
– Safe default serving mode (generate only).
– Optional Apache rewrite rules installation via explicit admin action.
– PHP-level WebP URL fallback in rewrite mode when .webp exists and browser supports WebP.
– Interactive media inspector with per-image conversion actions.
– Folder-based filtering and browsing inside the dashboard.
– Local audit log export (CSV) and clear actions.
– Local processing only. The plugin does not send images to an external optimization service.

FAQ
-
Does this plugin delete original images?
-
No. Original files stay unchanged.
-
Does this plugin convert animated GIF?
-
No. Animated GIF files are skipped by default to avoid breaking animation.
-
Does this plugin force rewrite rules automatically?
-
No. Apache rewrite rules are installed only when the admin explicitly clicks the install button.
-
Does this plugin send images or audit data to an external service?
-
No. Conversion runs locally on your WordPress server. Audit events are stored locally for administrator visibility and do not include visitor IP addresses.
