## Description

 * One-click bulk scan and convert of your entire Media Library, in safe small batches
   so it works even on shared hosting.
 * Converts the full-size image plus every registered thumbnail size (thumbnail,
   medium, large, etc.).
 * Auto-converts every new image the moment it’s uploaded.
 * Adjustable quality slider (default 82 — a strong quality/size balance).
 * Originals are never deleted; .webp files are created alongside them.
 * On the frontend, visitors whose browser supports WebP are automatically served
   the .webp version; everyone else still gets the original — no broken images, 
   ever.
 * Works with GD or Imagick, whichever your server has.

## Installation

 1. Upload the `stashpress-webp-image-conversion` folder to `/wp-content/plugins/`.
 2. Activate the plugin from the Plugins screen.
 3. Go to Media > StashPress WebP to run your first scan and adjust settings.

## FAQ

### Will this delete or replace my original images?

No. Originals are always kept. The plugin only adds .webp files next to them and
serves the .webp version to supporting browsers.

### What if my server doesn’t support WebP?

The plugin will show a notice on the settings page telling you GD/Imagick WebP support
isn’t available. Most modern hosts support this by default.

### Does it handle image sizes generated by page builders (Elementor etc.)?

Yes — it converts every size registered in WordPress’s attachment metadata, which
covers sizes added by themes and builders like Elementor.
