What is a WebP File?
Everything you need to know about Google's modern image format
WebP is a modern image format developed by Google that provides superior compression for images on the web. It supports both lossy and lossless compression, transparency, and animation, while producing smaller file sizes than JPEG and PNG.
Understanding WebP Format
WebP was developed by Google and released in 2010 as a next-generation image format designed specifically for the web. It uses advanced compression techniques to deliver high-quality images at significantly smaller file sizes compared to traditional formats.
The format supports both lossy compression (like JPEG) and lossless compression (like PNG), along with transparency and animation capabilities, making it a versatile choice for modern web applications.
Why Google Uses WebP
25-35% Smaller Files
WebP files are 25-35% smaller than equivalent JPEG files, meaning websites can load faster and use less bandwidth.
Better Quality
Despite smaller file sizes, WebP maintains superior image quality with advanced compression algorithms.
Advanced Features
WebP supports transparency, animation, and both lossy and lossless compression—all in a single format.
Modern Standard
As a modern format, WebP is built for today's web with better performance than legacy formats.
