<h4>Delete thumbnails & resized images from your Media Library</h4>
<ul>
<li>Delete some or all of WordPress’s resized images (thumbnails, medium, and large, plus extra ones Plugins/Themes make secretly)</li>
<li>This can clear thousands of unwanted files from your uploads directory </li>
<li>Useful if you’ve had lots of different theme/plugins over the years, and inadvertently accumulated a vast number of resized images that are no longer used by your site</li>
</ul>
<h4>Take careful note</h4>
<ol>
<li>Deleting is permanent</li>
<li>You can use <a href="https://wordpress.org/plugins/regenerate-thumbnails/" rel="ugc">this plugin</a> to regenerate your Media Library after (as WordPress will need the default sizes)</li>
</ol>
<h4>Please Note</h4>
<ul>
<li>🍺 This is a <strong>recently revived and re-written plugin</strong>, the bad reviews were correct for the old versions, but not current version. If you experience any issues, please open a support request, I’m happy to help fix any issues and help plugin grow.</li>
</ul>
<h3>Road Map</h3>
<h4>The current todo list</h4>
<ul>
<li>[ ] Add css animation/color to nag inputs when clicking disabled button</li>
<li>[ ] Add <code>count($this->library)</code> result as ‘exempt’ in main info banner to assure Media Library items are safe</li>
<li>[ ] Add size range filters (ie: delete resized that are within x – y restraints)</li>
<li>[ ] Make <code>View</code> link work off of a Lightbox instead of a new browser tab</li>
<li>[ ] Please add any additional requests into the Support tab.</li>
</ul>

<p>Ever have one erroneously entered custom field name confuse all of your users and you just can’t figure out how to get rid of it? Delete Custom Fields will let you delete every instance of a custom field from your site. Once your remove a custom field using this plugin it will not appear in your list of custom fields when you edit a post or page.</p>


Delete Custom Fields

Doesn't show all custom fields, though (even if you choose Show Hidden) - would be nice to have them as a list instead of a dropdown, but otherwise it does what it promises.

Works

Remove every instance of a custom field from your site.
