Advanced Custom Fields: Image Aspect Ratio Crop Field

Advanced Custom Fields: Image Aspect Ratio Crop Field


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.

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.

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.

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.

Aspect ratio

Use this option if you want the image to be of specific aspect ratio like 16:9 but the pixel size is not important.

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.

If you need a smaller image size, you make use of WordPress’s thumbnail functionality to access a smaller version of the image.

Pixel size

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.

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.

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.

Free crop

Crop can be done freely, there are no aspect ratio limitations.

Special thanks to Anders Thorborg for ACF Image Crop which served as a inspiration for this plugin. Also, thanks to Fengyuan Chen for the cropper.js library!


  • Cropping an image to 16:9 aspect ratio
  • Cropping in progress
  • Option to re-crop the image after upload


  1. Copy the acf-image-aspect-ratio-crop folder into your wp-content/plugins folder
  2. Activate the Image Aspect Ratio Crop plugin via the plugins admin page
  3. Create a new field via ACF and select the Image Aspect Ratio Crop type
  4. Read the description above for usage instructions


Can I use this plugin with a front-end acf_form?

Yes, this functionality has been added in version 5.0.0. Please test it and give feedback if you encounter any issues.

Can I access metadata in the original image from a cropped image?

Yes, the original image data is saved under original_image key in the returned ACF array. You can access data such as alt text, description and title this way.

Can I use this plugin with Elementor?

No, not really. Elementor only supports built-in ACF fields. Please contact Elementor support and ask them to add support for 3rd party fields. For some workarounds for limited Elementor support, see this post.

Can I use this plugin with Beaver Builder?

No, not really. Beaver Builder only supports built-in ACF fields. Please contact Beaver Builder support and ask them to add support for 3rd party fields. However, there is a work around this limitation by using a plugin called “Toolbox For Beaver Builder”. Please see their website for more details.

I have an issue or I want to contribute code

Please use the GitHub repository to raise issues about the plugin. You are also free to send a pull request on GitHub.

How is this different from the other plugin?

This plugin is similar to Advanced Custom Fields: Image Crop Add-on. I originally created a fork of that plugin to add functionality I need: specifying an aspect ratio instead of pixel size. Unfortunately the plugin doesn’t seem to be maintained anymore so my pull request was not merged.

So I created ACF Image Aspect Ratio Crop from scratch as an alternative to ACF Image Crop.

Possibility to use a pixel size instead of aspect ratio was added later on because I got so many requests for adding that feature.

The other plugin is not actively maintained and does not work well with latest ACF versions. I try to maintain this plugin as best as I can when new versions of ACF and WordPress come out.

This is absolutely fantastic! I no longer have to instruct my clients how to crop images for the web using Photoshop or similar tools, it’s all done within WP!I ran a few tests to see how well it works:- changed “image” ACF field to “Image Aspect Ratio Crop”. All existing image/page connections are retained.- changed the field back to “image” and disabled the plugin. All remains as is.This all feels very robust. What a great job creating this plugin, thank you so much!!

For us who use frontend forms to let visitors submit posts, this tool in incredibly useful! Functional, well-designed, and fast! I really love it, and frankly I don’t know what I’do without it. So thanks a lot for this awesome plugin!

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!

Exactly what i was looking for to ensure Users were uploading avatars in square format. Thank you

I was requested for “something” that prevent users from submit Featured Images with wrong/poor sizes. Adding this ACF to the Posts with a requirement of minimum size did the trick, and also gave them the ability to crop the image for opengraph sizes (1:1 and 1.91:1)

6.0.3 (2023-08-17)

  • Fix: Bump compatibility to WP 6.3
  • Fix: Fixed deprecation errors in PHP 8.1
  • Fix: Fixed warning about aiarc_temp_post_id if post is updated outside admin screen
  • Fix: Improved mime validation for frontend crop

6.0.2 (2022-08-24)

  • Fix: Bump compatibility to WP 6.0

6.0.1 (2022-02-01)

  • Fix: Bump compatibility to WP 5.9

Note: I’m currently working on version 7.0.0 of the plugin. This release will retain all the core functionality of the plugin, but it will feature a much improved code structure. This will make it easier to extend and to add more features to the plugin. Until 7.0.0 is released, I will not be adding any more features in the 6.x.x branch of the plugin. Despite this, bug fixes are of course provided. I have a lot of ideas for new features and improvements once 7.0.0 is released, so stay tuned!

6.0.0 (2021-10-20)

  • Breaking change: Changed how minimum and maximum image pixel sizes work
  • Minimum image size previously only affected the original uploaded file in aspect ratio mode. Now crop area must be larger than minimum dimensions.
  • Maximum image size previously only affected the original uploaded file in aspect ratio mode. Now if cropped area is larger than maximum dimensions, final image will be scaled down to maximum dimensions.
  • These changes do not apply to free crop mode, free crop minimum and maximum dimensions are disabled.
  • Pixel size mode has always had minimum dimensions. Enforcing maximum dimensions are now disabled for pixel size mode since the image is always scaled down to pixel size.

5.1.4 (2021-09-18)

5.1.0 (2021-01-30)

  • Feature: Added REST API compatibility mode. This enables you to crop images in the WordPress administration interface with admin-ajax.php instead of the REST API. You can enable this by going to Plugins -> ACF Image Aspect Ratio Crop -> Settings. Please note that this is a temporary fix for sites that don’t have REST API enabled. The compatibility mode will be removed in a future major release of the plugin.
  • Fix: Improved error logging

  • Breaking change: REST API is now used for cropping image instead of admin-ajax
  • Feature: Added frontend image crop. This allows you to use crop functionality with ACF forms on the front-end, even if the user does not have access to the media library.

I’d like to take this moment to announce that I have a GitHub Sponsors page. Maintaining this plugin is a lot of work and front-end image crop is one of those features I don’t use personally but I was requested so many times had to add it to the plugin, which took multiple days of work.

If you find this feature useful or if you otherwise want to support the development of this plugin, please consider supporting me on GitHub Sponsors. Thank you!
