Django Image Optimizer

A Django middleware and utility for optimizing uploaded images by converting them to WebP with configurable width, height, and quality settings.

Features

✔ Automatic optimization via middleware
✔ Manual optimization via utility function
✔ Supports per-request overrides
✔ Configurable defaults via settings.py

---

Installation

pip install django-optimize-image

Add the middleware:

MIDDLEWARE = [
    # other middleware...
    "optimizer_middleware.middleware.ImageOptimizationMiddleware",
]

---

Configuration

Set global defaults in settings.py:

# Default image optimization settings
IMAGE_OPTIMIZER_WIDTH = 800   # Resize width
IMAGE_OPTIMIZER_HEIGHT = None  # Keep aspect ratio
IMAGE_OPTIMIZER_QUALITY = 80  # WebP quality

By default, images are resized to 800px width while maintaining aspect ratio and optimized to 80% quality.

---

Usage

1️⃣ Automatic Optimization (Middleware)

Once added to MIDDLEWARE, the optimizer automatically processes all uploaded images in POST, PUT, and PATCH requests.

✅ Converts images to WebP
✅ Resizes based on settings.py

---

2️⃣ Dynamic Overrides (Per Request)

Override optimization settings dynamically in a view using request.META:

def upload_view(request):
    request.META["IMAGE_OPTIMIZER_WIDTH"] = 600
    request.META["IMAGE_OPTIMIZER_QUALITY"] = 90
    return some_response

---

3️⃣ Manual Optimization (Standalone Function)

Use the function anywhere in your code (views, forms, serializers, etc.).

from optimizer_middleware.utils import optimize_image

optimized_image = optimize_image(image_file, width=500, quality=85)
