What our users say ★★★★★ “We’ve halved the load time on mobiles of a site that we had already done quite a bit of work on to get image sizes down.” @martingfisher ★★★★★ “So far the best CDN plugin for WordPress. Please, never disappear!” @mavenickster ★★★★★ “I was looking for a CDN fast and easy (no need to code)! Sirv is the best – Just upload your photos to your WordPress library and voilà “roulez jeunesse!!!” (French expression). Very good service!” @disconance ★★★★★ “Sirv is fantastic! I have a lot of images on my website, and most of them are large, which resulted in slow site speeds, even with a CDN. What I love about Sirv is that they offer a CDN service, but also dynamically resize images based on the user’s browser/device, and serve the right file type. It has meant HUGE speed improvements on my website.” @basellen Optimal format (every time) Google loves next-gen image formats for SEO, but it’s a pain to convert all your images and keep track of them. Sirv solves that. It automatically delivers images to each user in the most optimal format. Usually that’ll be AVIF or WebP and the filesize is dramatically smaller, so Google will reward you with better search ranking. Sirv’s intelligence always serves the smallest possible file format to each users’ browser. It is 100% automatic. Plus, images are automatically scaled down to the suitable width/height and they’re lazy loaded, so you’ll really have the best possible image solution for WordPress.
