<p>A field for Advanced Custom Fields that forces the user to crop their image to specific aspect ratio or pixel size after uploading. Using an aspect ratio is especially useful in responsive image use cases.</p>
<p>After cropping, a new cropped image variant is created in the gallery and saved into the post. Thumbnails are also generated for the new image. User can re-crop the original image at any time from the post page.</p>
<p>The cropped image variants are hidden by default in the media browser and on the media page but you can view them by selecting the “list view” on the media page.</p>
<p>There are three modes of operation: aspect ratio, pixel size and free crop. You can select this option when creating the field in ACF field options.</p>
<h4>Aspect ratio</h4>
<p>Use this option if you want the image to be of specific aspect ratio like 16:9 but the pixel size is not important.</p>
<p>After selecting an image, user can select an area from the image that matches this aspect ratio. When crop button is pressed, the area is cropped from the original image.</p>
<p>If you need a smaller image size, you make use of WordPress’s thumbnail functionality to access a smaller version of the image.</p>
<h4>Pixel size</h4>
<p>Use this option if you need a specific pixel size image like 640×480. User will not be able to select an image smaller than the defined pixel size.</p>
<p>After selecting an image, user can select an area from the image they want, which can be larger than the pixel size but may not be smaller. The aspect ratio of the selection is locked according to the pixel size.</p>
<p>When crop button is pressed, the area is cropped from the original image. After the crop is complete, the image will be automatically scaled down to the pixel size. This means the final image will always be the specified size.</p>
<h4>Free crop</h4>
<p>Crop can be done freely, there are no aspect ratio limitations.</p>
<h4>Requirements</h4>
<ul>
<li>WordPress 4.9 or later</li>
<li>PHP 5.6 or later</li>
<li>Advanced Custom Fields 5.8 or later (Pro or Free)</li>
</ul>
<h4>Compatibility</h4>

Advanced Custom Fields: Image Aspect Ratio Crop Field

Wow, this plugin is absolutely PHENOMENAL! I sure hope that others will chip in and support this amazing developer. This plugin is perfect for allowing end users to add their own images without breaking your theme design.

I'm so glad I found this plugin.  My sincere thanks to the developer!

THE essential ACF Plugin

ACF field that allows user to crop image to a specific aspect ratio or pixel size

andersthorborg

<p>ACF image crop is an extended version of the native Image-field in ACF.<br />
The field gives the developer/administrator the option to predefine a size for the image, which the user is prompted to crop on the various edit screens. This solves the common issue of images being cropped inappropriately by the automated center-crop, that wordpress performs.</p>
<p>The plugin supports the defined image sizes as well as a custom option, enabling the developer to specify the dimensions from within the field edit screen.</p>
<p>The field can be configured to enforce a hard crop or a minimal-dimension-based crop. The hard crop will lock the aspect ratio of the crop where as the minimal-dimension-based crop will not allow the user to crop the image below the specified dimensions.</p>
<p>This plugin diverts from plugins like <a href="https://wordpress.org/plugins/manual-image-crop/">Manual Image Crop</a> in that when the user crops an image, a new attachment is generated, so that the relevant crop only applies in the context it is edited. It also keeps the user from dealing with the concept of various image sizes.</p>
<p>As of version 1.0 the field can be configured to either create the cropped image as a media-item (the default behavior) or simply create it and refer directly to the file without adding it to the media library. This will prevent the media library from being cluttered with several cropped versions of the same image. When this option is selected the only available return type for the field is URL.</p>
<h4>Compatibility</h4>
<p>This add-on will work with:</p>
<ul>
<li>version 4 and up</li>
</ul>


Advanced Custom Fields: Image Crop Add-on

So this plugin rocks but it seem to have a bug (might have been fixed), the new image that is generated from the cropping of the image is bigger in files size than the original. 

For example I would crop say 1000x1000px (size 30kbs) image and crop it down too 500x500px and the files size would be 60kbs. Ever time i would re-crop the image it would increase in file size.

Anyway great plugin



Love great plugin but ..
