Most of our image optimization tips require making some adjustments to their delivery URLs.
While this can be solved using our API, or by editing your images one-by-one with the provided UI support, there are other more easy and quick ways to achieve similar results.
Using "search & replace" tools (e.g. "Better Search Replace") you can locate all Cloudinary URLs on your application and have different transformation components attached to it, for example, the following will add automatic format conversion which usually causes Bandwidth consumption to drop significantly:
"https://res.cloudinary.com/demo/image/upload/demo/" => "https://res.cloudinary.com/demo/image/upload/demo/f_auto,q_auto/"
Attention: be careful when running these operations to avoid doing damage to your LIVE production.
