Prestashop Google WebP Image Converter

Prestashop Google WebP image converter module helps to convert various types of image formats into WebP format. WebP images use both lossy & lossless compression methods to produce the best quality images with lesser size.

WebP is an image format that provides lossless & lossy compression for images. It is used to make richer & smaller images for making web pages faster.

According to Google, WebP lossless images are 26% smaller than PNGs and WebP lossy images are 25-34% smaller than JPEG images. Lossless WebP compression applies already seen image fragments in order to exactly reconstruct new pixels. It can also use a local palette if it finds no interesting match.
