About This Conversion
What is JPG?
JPEG (Joint Photographic Experts Group) is the most widely used image format on the web. It uses lossy compression to achieve small file sizes, making it ideal for photographs and complex images with millions of colors. However, JPG does not support transparency or animation, and repeated saving gradually degrades image quality due to its compression algorithm.
What is WebP?
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, alpha channel transparency, and animation. WebP files are typically 25-34% smaller than equivalent JPG files at the same perceptual quality, making it an excellent choice for web performance.
Why Convert JPG to WebP?
- You want faster page loads — WebP files are 25-34% smaller than JPG at the same quality, directly improving website speed.
- You need transparency support — WebP supports alpha channel transparency, unlike JPG.
- You want modern compression — WebP uses advanced encoding techniques that outperform the older JPG format.
- You are optimizing for Core Web Vitals — smaller images improve Largest Contentful Paint (LCP) scores.
