Build Status Coverage Status

Usage

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" />
-->

Installation

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',
            ],
        },
    },
]

Possible problems

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.

Cleaning the cache

You can clean the cache running:

python manage.py clean_webp_images
