Images.weserv.nl

Design

wsrv.nl is an open-source image cache and resize service that allows you to manipulate images on-the-fly while leveraging a global cache. This ensures that your images load quickly and efficiently, no matter where your users are located. The service is built using best-in-class technologies such as nginx and libvips, and is backed by Cloudflare's CDN, which spans over 300 global datacenters.

• Crazy Fast: Performance is not just an afterthought; it's baked in from the start.
• Awesome Technology: Employs nginx and libvips for best-in-class performance.

• Fast Image Processing: Utilizes libvips for rapid and efficient image processing.

On average, wsrv.nl resizes 6 million images per hour, generating around 400TB of outbound traffic per month. This level of usage attests to its reliability and efficiency, making it a widely used solution for image manipulation and caching needs.
