# Introduction

Images.weserv.nl is an image cache & resize service. Our servers resize your image, cache it worldwide, and display it.

# How it works

You pass the image URL and a set of parameters. images.weserv.nl will then fetch the image, resize it, cache it and display it. The next time the request comes, it will serve the cached version.
