Google has introduced a new version of Accelerated Mobile Pages it calls AMP Lite. The new Web page format will take up to 45% fewer bytes than the standard AMP page to support slowernetwork connections.
AMP Lite, which compresses images and image data, will roll out globally for “bandwidth-constrained users” in countries such as Vietnam and Malaysia and for those with lowram devices. The changes may modify fine details of some images, but do not affect other parts of the page including ads, according to Software Engineers Huibao Lin and Eyal Peled.
The changewill optimize external fonts by using the amp-font tag, setting the font loading timeout to 0 seconds so thatpages display immediately regardless of whether the external font was previously cached or not, Google’s engineers wrote in a post.
Google also made improvement to image optimizations by AMP Cache. Changes made for AMP tooptimize image delivery range from removing invisible or difficult to view data, reducing color and quality of images without affecting visuals, and converting images to WebP format, which leadsto a 25% reduction in bytes and no loss in quality. A few other more techie changes are described by Lin and Peled.
