<p>WordPress generates several image sizes every time you upload a photo. Most themes and plugins add even more. If you’re not using all of them, they waste disk space and slow down uploads for no reason.</p>
<p>This plugin gives you a simple set of toggles under <strong>Tools</strong> to turn off what you don’t need:</p>
<ul>
<li><strong>Thumbnail sizes</strong> — Disable any default (thumbnail, medium, medium_large, large) or custom size registered by your theme or other plugins (WooCommerce, etc.).</li>
<li><strong>Image threshold</strong> — WordPress scales down images larger than 2560 px. Change that limit or disable it entirely so originals are kept as-is.</li>
<li><strong>JPEG quality</strong> — WordPress compresses JPEGs to 82% by default. Set your own value between 1 and 100.</li>
<li><strong>EXIF rotation</strong> — Some cameras store orientation in EXIF data and WordPress rotates accordingly. Turn that off if it causes problems.</li>
</ul>
<h4>How it works</h4>
<p>When you first activate the plugin it reads the current WordPress settings (including anything set by your theme or other plugins) so nothing changes out of the box. From that point on, the plugin takes over and you control everything from the settings pages.</p>
<h4>After you change settings</h4>
<p>You’ll need to regenerate thumbnails so the changes apply to images you already uploaded. We recommend:</p>
<ul>
<li><a href="https://wordpress.org/plugins/regenerate-thumbnails/" rel="ugc">Regenerate Thumbnails</a> plugin</li>
<li>Or via WP-CLI: <code>wp media regenerate</code></li>
</ul>
