JPG vs WebP

WebP keeps a photo looking the same at a fraction of the size, so pages load faster. Every current browser shows WebP, but some older desktop apps and upload forms still reject it, so keep the JPG for printing or emailing.

About the two formats

JPG

JPG is the default format for photos. It throws away detail the eye barely notices to keep files small, and every device made in the last 30 years can open it.

WebP

WebP was built to make web images smaller than JPG and PNG at the same quality. Websites use it widely, which is why images you save from the web are often WebP.

How to convert JPG to WebP

  1. 1Add your JPG files.

  3. 3Download the WebP files.
