## Description
**ADee** creates smaller, next-generation copies of your images and serves them
automatically to browsers that support them. Your original files are never modified
or deleted.
#### Features
* **WebP + AVIF support** — converts every image size (full size and all WordPress-
generated sizes).
* **Bulk conversion** — convert the entire media library from the dashboard with
a live progress bar and log.
* **Auto-convert on upload** — new images are converted the moment they are uploaded.
* **Smart serving, three modes** — Picture tag (default, works everywhere, cache-
safe), Server rewrite (fastest, auto .htaccess on Apache/LiteSpeed) or legacy
URL swap. Browsers that support AVIF get AVIF, older browsers get WebP, everything
else gets the original.
* **Serving test** — one click on the dashboard verifies that next-gen images are
actually being served on your site.
* **Originals stay safe** — variants are created next to the original files; nothing
is overwritten.
* **Engine detection** — uses PHP GD, Imagick or the cwebp/avifenc binaries, whichever
is available. You can override the engine per format.
* **Media library integration** — see WebP/AVIF status in a dedicated column, convert
or restore any image with one click, or use the “Convert to WebP/AVIF” bulk action.
* **Quality control** — separate quality sliders for WebP and AVIF.
* **FlynCache Purge integration** — purge your page cache right after a bulk run
with one click.
* **WP-CLI** — `wp adee status`, `wp adee convert all`, `wp adee restore all --
yes` and more.
* **Space savings report** — live stats for converted files, bandwidth saved and
average reduction.
#### Why WebP/AVIF?
WebP images are typically 25–35% smaller than JPEG, and AVIF can be up to 50% smaller—
with no visible quality loss. Faster pages, better Core Web Vitals, happier visitors.

## Installation
1. Upload the plugin folder to `/wp-content/plugins/` or install it from the Plugins
screen.
2. Activate the plugin.
3. Open the **ADee** menu in your dashboard, check the engine status and press **Start
Bulk Conversion**.
4. Purge your page cache so cached pages pick up the new URLs.
For AVIF support on servers without it: `apt install webp libavif-bin` (or use a
host with Imagick + AVIF delegate).
## FAQ
### Are my original images modified?
No. The plugin only creates additional `.webp` / `.avif` files next to your originals.
You can restore everything at any time from the dashboard or the media library.
### Which engine is used for conversion?
The plugin auto-detects in this order — WebP: GD Imagick cwebp; AVIF: Imagick
avifenc GD. You can override the engine per format in Settings.
### How does serving work?
The default **Picture tag** mode wraps images in a `` element with WebP/
AVIF sources — the browser picks the best format, no server configuration needed,
and the HTML is identical for every visitor (safe with all page caches). The **Server
rewrite** mode keeps the HTML untouched and lets the web server deliver the variant
per request; on Apache/LiteSpeed the .htaccess rules are managed automatically,
and nginx users can copy the snippet from the Help tab.
### I use a page cache. Anything to know?
The Picture tag and Server rewrite modes keep the HTML identical for all visitors,
so page caches are safe. Only the legacy URL swap mode can leave stale URLs in cached
HTML — purge your cache after bulk conversion. If FlynCache Purge is active, a one-
click purge button appears on the plugin dashboard.
### What about animated GIFs?
Animated GIFs are converted to a static first-frame WebP. If the WebP file would
be larger than the GIF, it is skipped automatically.
### What happens to variants when I edit or replace an image?
When WordPress regenerates the image metadata (scaling, cropping, editing), the
plugin re-converts the new files and removes stale variants automatically.
