django-image-cropping is an app for cropping uploaded images via Django's admin backend using imgareaselect. It keeps the original image intact, only cropping when the image is being displayed. Large images are presented in a small format, so even very big images can easily be cropped.

django-image-cropping is perfect when you need images with a specific size for your templates but want your users or editors to upload images of any dimension. It presents a selection with a fixed aspect ratio so your users can't break the layout with oddly-sized images.

It provides the necessary fields, widgets and a (easy_thumbnails) thumbnail processor for displaying the cropped image in your templates. Also works with FeinCMS content types!



  1. Install django-image-cropping using pip. For example:

    pip install -e git+ssh://
  2. Add easy_thumbnails and image_cropping to your INSTALLED_APPS. image_cropping is only required if you are using Django 1.3 and contrib.staticfiles

  3. Adjust the thumbnail processors for easy_thumbnails in your

    from easy_thumbnails import defaults
    ) + defaults.PROCESSORS
  4. Deploy the necessary static files:

    If you are using Django 1.3 and contrib.staticfiles the necessary static files should be picked up automatically. In all other cases you have to copy or symlink the static files. Depending on your setup the command should look similiar to this:

    ln -s ~/.virtualenvs/yourenv/src/django-image-cropping/image_cropping/static/image_cropping/


In order to make a regular ImageField croppable, simply turn it into an ImageCropField. Then add an ImageRatioField, which will contain the boundaries of the cropped image. The ImageRatioField expects the name of the associated ImageCropField as the first argument and the size of the final image to be displayed as the second argument.

The size is passed in as a string and defines the aspect ratio of the selection as well as the minimum size for the final image. If the user tries to crop an image that's smaller than this minimum, the selection is locked.

  1. Model fields and options:

    from image_cropping.fields import ImageRatioField, ImageCropField
    image = ImageCropField(blank=True, null=True, upload_to='uploaded_images')
    # size is "width x height"
    cropping = ImageRatioField('image', '430x360')
  2. If your setup is correct you should automatically see the enhanced image widget that provides a selection area for the image in the admin backend.

  3. Example usage of the thumbnail processor:

    {% thumbnail yourmodel.image 430x360 box=yourmodel.cropping crop detail %}
  4. Additionally you can define the maximum size of the preview thumbnail in your

    # size is "width x height"


If you need the same image in multiple formats, simply specify another ImageRatioField. This will allow the image to be cropped twice:

from image_cropping.fields import ImageRatioField, ImageCropField

image = ImageCropField(blank=True, null=True, upload_to='uploaded_images')
# size is "width x height"
list_page_cropping = ImageRatioField('image', '200x100')
detail_page_cropping = ImageRatioField('image', '430x360')

In your templates, simply use the corresponding ratio field:

{% thumbnail yourmodel.image 200x100 box=yourmodel.list_page_cropping crop detail %}
