</ul>
This is a third-party plugin developed by Web Wonderland. 
It is not affiliated with or endorsed by WordPress, Elementor or WPBakery.
<h3>Local vs Cloud processing</h3>
The optimiser can work in two ways:
Local processing (always available) 
Runs entirely on your own server.
<ul>
<li>Unlimited WebP and AVIF generation (subject to your servers capabilities)</li>
<li>No monthly conversion caps</li>
<li>No api key required</li>
<li>Uses your own CPU and disk I/O</li>
</ul>
Cloud/API processing (api key required) 
Offloads heavy image work to the Web Wonderland Image API.
<ul>
<li>Uses a remote worker to generate WebP/AVIF for originals and all sizes</li>
<li>Reduces CPU load on your hosting, useful for busy or shared servers</li>
<li>Quotas and limits depend on your Lite, Pro or Unlimited plan</li>
<li>Works alongside local mode you can always fall back to local processing</li>
</ul>
You can choose your preferred processing mode in SEO Image Optimiser – Settings.
<h3>Free (Lite API Key)</h3>
The Lite API Key requires no card, only an email to issue an API key.
Included in the Lite API Key plan:
<ul>
<li>Unlimited local image conversions (WebP/AVIF) on your own server</li>
<li>Up to 50 cloud/API image conversions per month (WebP + AVIF) via the Web Wonderland Image API</li>
<li>Front-end WebP & AVIF delivery if available</li>
<li>Up to 30 AI alt tag & title generations per month</li>
<li>Automatic backups of originals with one-click restore</li>
<li>Works on one WordPress site</li>
</ul>
Your previously converted images remain on your server regardless of the API Key status. 
If your monthly cloud API quota is reached, the plugin can still optimise images locally.

<h3>AI & Privacy</h3>
AI captioning is optional. If enabled, SmartAlt uses external services as documented in the External services section below. The plugin does not send personal data about site visitors.
<h3>External services</h3>
This plugin can connect to external services operated by Web Wonderland to provide optional “cloud” features (remote image optimisation and AI-powered SmartAlt captions). Local-only optimisation features continue to work without any external service.
When any cloud feature is enabled/used, the plugin sends requests from your WordPress server (admin-side actions) to the endpoints below. The plugin does not send personal data about site visitors.
