What Is WebP? Benefits, Quality, and Website Uses

WebP is an image format designed for efficient image delivery on the web. It supports both lossy and lossless compression, along with transparency and animation.

Why Was WebP Created?

WebP was created to provide efficient compression compared with older formats such as JPG and PNG while maintaining strong visual quality.

WebP File Size

WebP images can often be smaller than equivalent JPG or PNG images. Smaller files require less data to download and can help reduce page weight.

WebP vs JPG

JPG remains highly compatible and is still useful for photographs, but WebP can often achieve a smaller file size at a similar visual quality.

WebP vs PNG

WebP can support transparency, making it useful for some graphics that would traditionally be saved as PNG. The best option depends on the image and the software or platforms involved.
