Guess which image has been optimized by Sirv

Original image Image 2
Processed image Image 1

The answer…

The image to the left has been losslessly compressed by Sirv.

The image to the right is the original JPEG, of 94.89 kB size. The optimized image to the right is a WebP of just 38.20 kB (served to Chrome & Opera). Other browsers will receive a JPEG of just 47.21 kB.

That’s a saving of 60% (WebP) or 50% (JPEG), without sacrificing quality.

Even smaller file sizes

The default Sirv quality setting is 80%. For even greater savings, try dropping the quality lower. It’s as simple as tweaking the Default profile in your Sirv account, or adding ?q=50 to your image URL.
