How can I use a Cloudflare Worker to automatically resize images uploaded to an S3 bucket?

You can create a Cloudflare Worker that listens for S3 object creation events within a specific bucket. Upon receiving an event, the Worker downloads the uploaded image from S3, resizes it to various sizes (e.g., thumbnails, medium, large), and then uploads the resized images back to the same or a different S3 bucket. This automated process eliminates the need for separate image processing services and improves user experience by delivering optimized images.
