Intelligent CDN, built for media

Deliver perfectly optimized files to each visitor, based on their viewport, browser and connection speed.

Improve your CDN efficiency

Bandwidth usage typically reduces by 50-70% when switching to Sirv. Every Google PageSpeed image recommendation is either automatically applied or easily implemented.

By achieving the best-possible page optimization, your content will load faster, keep users engaged, improve SEO and cut your bandwidth costs.

Instant purging

Unlike other CDNs, Sirv automatically invalidates the cache of all old file variants when a new file is uploaded. Your visitors will always see the latest file and you’ll never need to manually purge the CDN cache again.

Performance analytics

Discover how and where your files are being served, with detailed analytics.

Track the loading speed of your files to understand the impact of your web developer’s page optimisations. Identify the most popular content, to make better informed content creation decisions.

What is an image CDN?

An image CDN is deliberately optimized for the most ideal image to each user. By calculating the viewport space, browser and screen resolution, the CDN will return a perfectly scaled image, compressed in the most optimal next-gen image format (e.g. AVIF). This is the easiest way to achieve every Google PageSpeed best practice, with little or no input required from your web developer.

Automatic next-gen formats

Sirv CDN delivers the most optimal image format. Next-gen formats such as AVIF are usually 20-70% smaller than the JPEG or PNG original image. Conversion happens automatically on-the-fly, so your images will always meet Google’s recommendations, without any effort.

Always on optimization

Achieving your fastest possible loading time is a breeze with Sirv CDN. You don’t need to think about optimization – not even spend time configuring settings. Optimization is on by default for all file types, to deliver them as fast as possible to your visitors.
