Why convert JPG to WebP?
JPG is the most widely supported image format in the world. It uses lossy compression tuned for photographs, which keeps files small at the cost of a little detail. It cannot store transparency.
WebP files are usually 25–35% smaller than JPG at the same visual quality. Converting images to WebP makes websites and online stores load faster, which also helps search rankings.
Good to know
- Use the quality slider to balance size and quality. 80–90% is visually lossless for most photos.
