Let's assume we have this simple model: from django.db import models class Image(models.Model): image = models.FileField(upload_to="images/")   Task is to take this simple image, rotate it and save instead of original. Let's discover this way to do so: #views.py from PIL import Image as PilImage from models import Image def rotate(request): #getting instance of the model item=Image.objects.get(pk=1) #opening image for PIL to access im = PilImage.open(image.image) #rotating it by built in PIL command rotated_image = im.rotate(270) #saving rotated image instead of original. Overwriting is on. rotated_image.save(item.image.file.name, overwrite=True) return HttpResponse(str(image.image)) This pattern will work in most cases.  Instead of rotate you can use any other PIL editing method, as for e.g. flip or sharpen the image... Have fun coding and please leave me a comment if you'll find this info useful. ...
