Introduction

wsrv.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. wsrv.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.

TIP

If the URL includes a querystring, you'll need to ensure that it's properly URL-encoded, replacing ? with %3F and & with %26, respectively.
