Why convert images to WebP
WebP is a strong default for modern websites because it supports lossy compression, lossless compression, and transparency in one web-friendly format. For many photos and product images, the file size can be noticeably smaller than JPG at similar visual quality.
Use WebP when you control the website or app where the image will be served. If you are sending a file to a legacy system, JPG or PNG may still be the safer compatibility choice.
