Fiz Auto Media helps site owners manage common media and publishing tasks from one plugin.
Developed By FizTool. 
Plugin website: https://fiztool.com/
Main features include:
<ul>
<li>Image compression and WebP generation for supported media files.</li>
<li>Bulk compression workflow for existing Media Library images.</li>
<li>Automatic image alt text and description helpers.</li>
<li>Featured image tools for posts without thumbnails.</li>
<li>Duplicate post detection tools.</li>
<li>Auto post scheduling tools using WordPress cron.</li>
<li>Media cleaner tools for scanning and reviewing unused media before cleanup.</li>
</ul>
Fiz Auto Media runs locally inside WordPress and does not require an external account for its included features. If the Featured Image helper is enabled, WordPress may request external image URLs found in post content so those images can be imported into the Media Library after the required upload and edit permissions are confirmed.
The plugin uses WordPress capabilities, nonces, sanitization, escaping, and WordPress filesystem helpers where appropriate.
