Introduction #

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

• We support a good range of image formats, including JPEG, PNG, BMP, GIF, TIFF, WebP, PDF and SVG.
  • There's even support for animated WebP and GIF images.
• We support IPv6, serving dual stack, and supporting IPv6-only origin hosts.
• For secure connections over TLS/SSL, you can use https://wsrv.nl/.
  • This can be very useful for embedding HTTP images on HTTPS websites. HTTPS origin hosts can be used by prefixing the hostname with https://.
• The CDN is provided by Cloudflare. Images are being cached and delivered straight from
  200+ global datacenters. This ensures the fastest load times and best performance.

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.
