This original image was uploaded at 3,434 × 2,447 pixels — fine for a 4k TV on a fast connection, but too big for a typical HD computer monitor, and overwhelming for a phone.
We need a way to fit the image to the device so the website doesn’t bog down and the user has a good experience.
Optimole does this by compressing the image in Google’s WebP format, which is about 25% smaller than typical JPEG files.
Then, Optimole re-sizes the image to exactly fit the user’s viewport, meaning it fits the image to each user’s display regardless if they are using a TV, monitor, tablet, or phone.
Efficient compression plus on-the-fly re-sizing — that’s the combination that gets users exactly what they need. No more, no less.
At Optimole’s medium compression setting, this full-width image on a HD desktop display is just 161 KB — a whopping 92% decrease from the original JPEG file size.
