Django Image Compressor is a tool for optimizing your website's static images for serving in production. Django Image Compressor
alters the staticfiles.json manifest generated after running collectstatic by changing the image mapping to
the new optimized images located in a directory in STATIC_ROOT.
pip install django-image-compressor
Add to INSTALLED_APPS
INSTALLED_APPS = [
# some other apps...
'imagecompressor'
]
Run collectstatic
python manage.py collectstatic
Run compressimages
python manage.py compressimages
Positional arguments
path- The path relative to
STATIC_ROOT, or app name, whose images you want compressed. - Optional Arguments
--optimize If present and true, indicates that the encoder should make an extra pass over the image in order to select optimal encoder settings. --quality QUALITY The image quality, on a scale from 1 (worst) to 95 (best). --progressive If present and true, indicates that this image should be stored as a progressive JPEG file. --lossless If present and true, instructs the WEBP writer to use lossless compression.
For more information on these options see the Pillow documentation.
python manage.py compressimages --optimize --progressive --quality 75
Will optimize all JPG, and PNG files in STATIC_ROOT, and make JPGs progressive with quality 75.
python manage.py compressimages polls --progressive
Will make all JPG files in the polls app progressive with Pillow defaults for the other parameters. Again see the Pillow documentation.
python manage.py compressimages
This is the first example in "Getting started". It will not modify the images at all, instead it will rename them and place them in a new directory in STATIC_ROOT.
| IMAGE_COMPRESS_ROOT: | This is the name of the directory images will be placed in after running compressimages (Default: 'IMAGES'). |
