JPG - Joint Photographic Experts Group
JPG uses a lossy compression method that relies on the discrete cosine transform (DCT). This algorithm works by converting image data from the spatial domain into the frequency domain, where...
WebP - Web Picture Format
WebP uses predictive coding to encode images, similar to how keyframes are handled in video compression. The algorithm looks at neighboring blocks of pixels to predict the values in a block ...

Conversion Objective
This path is webP is best used for all types of web-based imagery where performance and speed are priorities. It is the ideal choice for modern websites looking to optimize their LCP (Largest Contentful Paint) scores by serving high-quality images with much smaller file sizes than traditional JPGs. It is also excellent for UI elements that require transparency, as it provides a much more efficient alternative to PNG. Developers use WebP for everything from small icons and thumbnails to large hero images and animated banners. Since it is now supported by all major browsers, it can be used as the primary format in <img> tags or CSS background images. Many content delivery networks (CDNs) and CMS platforms now automatically convert images to WebP on-the-fly to ensure the best possible performance for end-users.It translates the binary structure of JPG into the WebP specification without intermediate cloud storage or external processing queues.
