## Description

JZB Image Auto AVIF is an image optimization engine that helps WordPress users automatically
generate compressed AVIF and WebP images. It does this without altering the original
media library files, utilizing an independent cache directory architecture to safely
serve optimized images to browsers.

### Core Features:

 * **Non-destructive Cache**: Generated AVIF and WebP files are stored in a separate`
   wp-content/uploads/jzb-image-auto-avif/` directory. Uninstalling the plugin instantly
   restores your original media library.
 * **Dual-Core Compression**: Configure distinct quality settings for AVIF and WebP
   formats. Supports fine-grained adjustment and switching between lossy and lossless
   modes.
 * **HTML Output Buffering**: Dynamically replaces image links in the front-end 
   HTML source without relying on `.htaccess` or `nginx.conf` rewrite rules.
 * **Native Intervention Control**: Provides toggles to prevent WordPress from generating
   unnecessary multi-size thumbnails or applying `-scaled` changes, helping to save
   server disk space.
 * **Media Library Controls**: Includes AJAX buttons in the Media Library list view
   to generate AVIF/WebP for individual old images or cleanly delete legacy thumbnails.
 * **Dynamic Loading Thresholds**: Recommends sizing configurations based on your
   server’s available CPU cores and RAM to prevent server timeouts during heavy 
   image conversion.

## Installation

 1. Upload the `jzb-image-auto-avif` folder to the `/wp-content/plugins/` directory,
    or upload the ZIP file directly via the plugins screen.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.
 3. Navigate to **Media -> Image Auto AVIF** to configure the plugin settings.
 4. Input your server specifications to receive a recommended pixel limit, and select
    your target formats.
 5. Check the recommended native intervention options and save settings.

## FAQ

### Why are images still showing as JPG/PNG on the front-end?

The plugin uses HTML output buffering to replace URLs on the fly. If you use a caching
plugin (like WP Super Cache, WP Rocket) or server-level caching, you must **purge
your entire site cache** after activating this plugin.

### Will I lose my original images if I deactivate the plugin?

No. The plugin uses a bypass architecture. Original images are kept intact in the
default WordPress `uploads` folder.

### How do I optimize old images?

Switch your Media Library to the « List View ». You will see generation buttons 
underneath each image.
