The search giant has developed a new kind of image format that promises to shrink the size of Web photos and graphic files down by about 35%. That's a big deal, considering that images are responsible for nearly two-thirds of the size of an average website — a figure that grew by more than 30% last year, according to the HTTP Archive.
To boost load times for websites, Google (GOOGL, Tech30) developed a new image format, called WebP. At its I/O developers conference last month, Google announced that it has converted most of YouTube's thumbnail images to WebP, improving the site's load time by 10%. That may not sound like much, but Google says that alone has saved users a cumulative 140,000 hours each day.
Google has also changed the Chrome Web store and Google Play store over to WebP, speeding up load times on those sites by nearly a third. Facebook, Netflix, eBay (EBAY, Tech30) and several other websites have also begun supporting WebP.
