WebP
WebP is an image format from Google that produces significantly smaller files than JPEG or PNG while maintaining the same visible quality. In practice, savings of 25 to 35 percent are common, and even more for graphics with few colors.
For example, a product photo with a width of 1600 pixels weighs about 420 kilobytes as a good-quality JPEG. The same image as WebP is around 280 kilobytes, with no visible difference. With twenty images on a page, that's almost three megabytes less that don't need to be transmitted over a mobile connection.
WebP also supports transparency like PNG and animation like GIF, but is significantly more resource-efficient. It's supported by all current browsers, so you practically don't need a fallback format anymore.
Two things to keep in mind when converting: Create WebP from the original file, not from an already compressed JPEG, otherwise the quality loss will add up. And keep the originals in case you need to crop them further later. With our hosting packages, the conversion happens automatically when you upload.
