Every time you upload an image, WordPress doesn’t just store your file — it generates a separate cropped copy for every registered image size. A fresh install already creates three (thumbnail, medium, and large) on top of the original, so a single upload becomes four files on your server.
Themes and plugins add many more. A typical site might register hero, slider, product thumbnail, team member, and testimonial sizes — and WooCommerce adds several of its own. With six registered sizes, one upload turns into seven files, even when the page only ever displays one of them. The rest sit on disk doing nothing but consuming space.
Multiply that across hundreds of posts, pages, and products and the waste adds up fast: bloated storage, slower backups, and longer upload processing. It’s especially painful on WooCommerce sites, where uploading a single banner or hero image also generates the full set of product thumbnail sizes you’ll never use for that image.
WP Image Sizes fixes this by letting you decide which sizes WordPress is allowed to create.
<ul>
<li>Per post type control — Assign the exact image sizes that matter to each post type from a simple settings page. A slider post type might only need one large size; testimonials might only need a thumbnail.</li>
<li>Choose sizes at upload time — When you add media, the uploader shows the available sizes so you can pick what gets generated for that specific upload.</li>
<li>Disable thumbnails entirely — Skip generating any additional sizes for a post type or a single upload when you only need the original.</li>
<li>No lock-in — WP Image Sizes never caches or alters your files. Any images already generated stay intact, even if you deactivate or remove the plugin.</li>
</ul>
The result is a leaner media library, less wasted disk space, and a faster, lighter WordPress site.
<h3>PRO</h3>
The free plugin controls which sizes get generated on new uploads. WP Image Sizes Pro extends this to your existing media and adds automation:
<ul>
<li>Bulk Create Image Sizes — Generate selected image sizes for all existing images of a chosen post type. Perfect after registering a new size or switching themes.</li>
<li>Bulk Delete Image Sizes — Remove unwanted image size files from existing media to reclaim server space in one click.</li>
<li>Create Images on Runtime — Automatically generate a missing image size the moment it is first requested on the front end, instead of pre-creating every size.</li>
</ul>

This is an easy and fast way to crop any uploaded image in your wordpress. No more complicated graphical editors, photos of people without head or products with wrong view. Select a thumbnail, edit the crop area and save the new thumbnail image.
This plugin doesn’t create any new file or folder, when it saves the new crop area it rewrites the original thumbnail file, this means it doesn’t affect the theme design 🙂
<h3>Features</h3>
<ul>
<li>The plugin automatically use all images created with the function add_image_size even if they are hard cropped or proportional. More info in https://codex.wordpress.org/Function_Reference/add_image_size#Crop_Mode</li>
<li>“Crop Editor” quick link in media list.</li>
<li>“Crop Editor” link in featured image widget.</li>
<li>“Crop Editor” button inside file details in media manager.</li>
</ul>

<h3>How to use it</h3>
<ol>
<li>Select an image, open the image editor and click on the Crop Editor button.</li>
<li>Choose the image size you want and crop it.</li>
</ol>
<h3>Recomendations</h3>
If you are a developer and you need to rebuild the thumbnails we recommend use this plugin: https://wordpress.org/plugins/ajax-thumbnail-rebuild/ it helps you to do it one at a time.
IMPORTANT: Notice that rebuilding thumbnails will overwrite the thumbnails cropped with the TTT Crop plugin.
<h3>Hacks</h3>
Just copy&paste this code into your functions.php
Remove sizes from the editor
<pre><code>add_filter( 'tttcrop_image_sizes', 'custom_tttcrop_image_sizes');
function custom_tttcrop_image_sizes( $sizes ) {
 unset( $sizes['thumbnail'] );
 unset( $sizes['large'] );
 return $sizes;
}
?>
</code></pre>
Remove thumbnails sizes from the editor for an specific post type
<pre><code>function custom_tttcrop_image_sizes_CPT($sizes) {

 foreach ($sizes as $key => $values) {
 if ($key == 'THUMBNAIL-SIZE1')
 $new[ $key ] = $values;
 elseif ($key == 'THUMBNAIL-SIZE1')
 $new[ $key ] = $values; 
 }

 return $new;
}
</code></pre>
Change the name of the image to human friendly names
<pre><code>function local_ttt_crop_human_name($name) {
 switch( $name ) {
 case 'single-slider';
 return 'Home slider image'; break;
 case 'widget-thumbnail';
 return 'Widget small image'; break;

 default:
 return $name; break;
 }
}
add_filter('ttt_crop_human_name','local_ttt_crop_human_name');
</code></pre>
This will change the name of the image inside the tooltip when it is selected.
