# Image optimization basics (video tutorial)

## Overview

Large images slow down websites and hurt performance scores. This tutorial shows how to optimize any image in Cloudinary with a simple two-parameter URL change: `q_auto` for automatic quality compression and `f_auto` to automatically serve the best file format for each browser.

No code required. Just edit the delivery URL and your images are instantly optimized for every device. Learn more in the [image optimization](image_optimization) guide.

|{videotime:id=media :min=0 :sec=02 :player=cld} | Images stored in the cloud are often much larger than they need to be when delivered to a website. Cloudinary makes it easy to automatically compress and convert your images with a single URL change. |

### Choose an asset and copy its URL

|{videotime:id=media :min=0 :sec=16 :player=cld} | Start by choosing any asset from your media library — a photo, icon, or hero banner — and copy its delivery URL. This is the link used in your website to display the image. |

### Add q_auto and f_auto
