Try demos.
360 spin
Shoppers adore spinning products around to see them from all sides. If you’re selling something online, maybe with WooCommerce, Sirv provides a stunning 360-degree photography experience. Sketch diagram software. Simply upload a set of photos and a 360 spin will be immediately ready to embed in your page. It feels incredible on desktop and mobile alike, especially the big full-screen 360 spin view.

What our users have to 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
Widsmob screen recorder 1 1. ★★★★★ “I was looking for a CDN fast and easy (no need to code)! Sirv is the best – Just upload your photos on 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)
WebP is probably the best image format you’ve never heard of. Incredibly, it has the same quality of a JPEG, yet its typically 30% smaller in file-size (versus Sirv’s already outstanding JPEG compression).
Sirv is intelligent enough to always serve the smallest possible file format that each of your users’ browser supports. For Chrome & Opera, that’s usually WebP. Another reason why your pages will instantly load faster, once you install the Sirv plugin for WordPress.
All this is 100% automatic. Add in lazy loading and responsive images and you truly have the best possible image delivery system for WordPress.

FAQ
Is Sirv free to try?
You can try Sirv for 30 days without any obligations. Then you have the option to downgrade to a free plan with 500 MB storage and 2 GB of bandwidth. Or you can choose one of our pricing plans.
How do I enable WebP image optimization?
WebP is enabled by default. Sirv automatically optimizes your images in the most suitable format for each users’ browser and screen. WebP is usually the smallest file-size for Chrome and Opera, so your images will be served in WebP format (regardless of what image format your original images are). Other browsers will receive either JPEG or PNG, whichever is most optimal.
Can I serve images from my own domain name?
You can serve images from any domain or subdomain that you own. All you need is an SSL certificate for that domain/subdomain. You’ll update your DNS to point the CNAME to your Sirv account, then all your images will be optimized and served rapidly over HTTPS from Sirv. Follow this short tutorial.
Can I host other files, as well as images?
You can serve almost any file from your Sirv account. Use it as a WordPress CDN to deliver JS files, CSS files, text/CSV/XML files, PDFs, PSDs and more. Think of Sirv as a complete CDN hosting solution for all your files, with the best possible image optimization and delivery.
What happens to my original images if I disable the plugin?
Your images are perfectly safe, Sirv does not modify them. After you turn off our plugin your site keeps working just the way it did before.
What makes Sirv stand out among other image optimization plugins?
Your original images are left untouched. Sirv serves your images from a robust CDN. It automatically resizes and optimizes all of your images on-the-fly allowing for a superb experience for each and every user, on any device, from any country in the world.
What formats does Sirv support?
JPEG, PNG, GIF, WebP and many more.
Is Sirv better than other WordPress image optimization plugins?
People tell us they prefer Sirv to other plugins (Smush, Cloudinary, ImgIX, Imagify, ShortPixel) because Sirv optimizes images smaller, the Sirv plugin is entirely automated and images load faster anywhere in the world, thanks to Sirv’s CDN.
Can I use Sirv with Cloudflare?
Yes. Clouflare and Sirv work perfectly together on the same site. Sirv will serve your images, Cloudflare will serve your other files.
The plugin doesn’t work with my theme
Sirv works instantly on over 95% of WordPress sites. In case Sirv doesn’t instantly work for you, we can usually resolve that within 24 hours (Mon-Fri). Just send us a message containing a login to your WordPress admin from this secure form and our helpful team will find and resolve the problem ASAP.
I’m a photographer, can I keep my EXIF data?
Yes, you can keep your image meta data, including any copyright information. Learn how.
Sirv also helps you protect your images with watermarks and hotlink protection. Learn how.
Can I use Sirv with Elementor?
Yes, Sirv works with Elementor. The Sirv plugin automatically copies your Elementor images to your Sirv account. There’s also a button in Elementor to “Add Sirv Media” to your pages.
Can I use Sirv with Divi?
