## Beskrivelse

Clevers Image Optimizer optimizes local WordPress images and generates modern formats(`.
webp` and optional `.avif`).

Since version 0.3.0, processing runs in the background with queueing and batch/time
limits to avoid admin timeouts during large uploads.

#### Features

 * Local optimization of original JPG/PNG files.
 * WebP generation.
 * Optional AVIF generation.
 * `.htaccess` rules for transparent delivery.
 * Media Library bulk action to queue optimization jobs.
 * Background processing with configurable limits.

#### Composer/Vendor policy

This plugin uses Composer as the source of truth for dependencies.

 * Development/CI: install dependencies with `composer install`.
 * Release: the published ZIP includes `vendor/` for WordPress environments without
   Composer.

## Installation

 1. Upload the plugin to `/wp-content/plugins/clevers-image-optimizer` or install it
    from the release ZIP.
 2. Activate it in WordPress.
 3. Go to `Settings > Clevers Image Optimizer`.
 4. Configure WebP/AVIF quality and background processing limits.

## FAQ

### How does background processing work?

New images and bulk actions are queued. A scheduled event processes the queue in
batches (`Batch size`) and respects a maximum runtime (`Time limit per run`).

### What if AVIF is not supported on my server?

The plugin shows capability status in settings. If `imageavif` is not available,
AVIF files are not generated.

### Do I need Composer in production?

No, if you use the official release ZIP. Composer is only needed for local development
and CI.
