Google developed the WebP format for those who want images on their websites to load faster. It enables web masters to add high-quality pictures that are smaller than images in PNG and JPEG formats. When saving a WebP file, you can choose between lossless or lossy compression. The latter means that an image will be saved without non-essential data.

You can view WebP in Google Chrome, Firefox, Edge, and Opera. Thanks to predictive coding, this format compresses images and graphics without quality loss. Besides, WebP animations are a great alternative to GIF files. They are much smaller, which makes them more convenient to use.

How WebP File Works

Many people are wondering what is WebP compression. Thanks to it, you can use predictive coding to convert your images without quality loss. The same encoding method is used by the VP8 codec, which allows compressing videos. This way of encoding analyzes the values in neighboring blocks of pixels to make predictions about other values. Thus, it encodes only the difference between different values.

WebP compression allows using pixels to predict the value of other pixels. If no match is found, a local palette is used.

A WebP picture contains VP8 or VP8L data as well as a RIFF-based container. The libwebp library enables adding WebP encoding or decoding to programs and apps. It can be downloaded from the GitHub repository or as a TAR archive.

WebP format was created for optimizing images for web use. It is somewhat similar to such widely-used image formats for print as JPEG and PNG. Such files have the .WEBP extension. To save such pictures on your device, you need to right-click on them and select the “Save Image As” option.
