How do JPG and WebPcompare? Here's everything you need to know to choose the right format — and how to convert between them.
Joint Photographic Experts Group
JPG (also known as JPEG) is the most widely used image format for photographs and complex images. It uses lossy compression to significantly reduce file size while maintaining acceptable visual quality.
Web Picture 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 — all in one format.
