Returns a webp image instead of jpg, gif or png to browsers which have support.

Load the webp module in your template and use the webp templatetag to point to the image you want to convert.

{% load webp %}

{# Use webp as you would use static templatetag #}
<img src="{% webp 'path/to/your/image.png' %}" alt="image" />
<!--
If the browser has support, generates:
<img src="/static/WEBP_CACHE/path/to/your/image.webp" alt="image" />

else, generates:
<img src="/static/path/to/your/image.png" alt="image" />
-->

First of all, you must install the webp support. In ubuntu you can install via apt-get:

apt-get install libwebp-dev

Please, check the official guide for the other systems.

Then, install django-webp.

pip install django-webp

add it to INSTALLED_APPS configuration

INSTALLED_APPS = (
    'django.contrib.staticfiles',
    'django_webp',
    '...',
)

add the django_webp context processor

TEMPLATES = [
    {
        '...'
        'OPTIONS': {
            'context_processors': [
                '...',
                'django_webp.context_processors.webp',
            ],
        },
    },
]

django-webp uses Pillow to convert the images. If you’ve installed the libwebp-dev after already installed Pillow, it’s necessary to uninstall and install it back because it needs to be compiled with it.

You can clean the cache running:

python manage.py clean_webp_images
