Faster pages with the same photos
Online shops, portfolios and blogs are often slow because of their photos. At similar visible quality, a WebP image is usually clearly smaller than a JPG, so pages load faster – particularly on mobile connections. Many shop systems and content management systems accept WebP uploads directly.
What to keep in mind
The WebP encoder of your browser is used, so this works in Chrome, Edge and Firefox. Safari shows a message instead of producing a wrong file.
- Keep your original JPGs: WebP is meant for publishing, the JPG stays your master copy.
- Converting an already compressed JPG can't bring back detail – it only stores the image more efficiently.
- “Medium” quality is a good choice for large galleries; use “High” for hero images.
- Width and height stay the same. To make images smaller in pixels, resize them before converting.
About JPG and WebP files
- JPG / JPEG
- JPG is the most common photo format, used by phone cameras and on the web. It keeps file sizes small by compressing image data.
- WebP
- WebP is a modern image format from Google that makes web images smaller than JPG or PNG. Many websites deliver their pictures as WebP, but some programs and upload forms still don't accept it.
