I convinced everyone at work to set up an img proxy 8 months ago, and we've been very happy with it ever since. We proxy all images on the fly: avif, webp, and compressed jpg. Now, we don't worry about someone uploading a large picture to the CMS. So, I wish you 1st place; you definitely deserve it! 💪🏻

@matija With imgproxy, you can resize and crop images, convert them to different formats, add watermarks, apply filters, and more; everything's on the fly. With the Pro version, you can generate previews for videos and PDFs, detect objects in the image, auto-adjust quality, automatically pick the best format for the image, and more. Our website has a demo of the most used features: https://imgproxy.net/#demo
