Comparison between JPG and WEBP


JPG is a compressed graphic format. It means that the JPG format is used to save images and that it compresses those images so that they occupy less space on the disk. JPG makes lossy compression, which means that it is a graphic format that compresses images and in this compression the resulting image is not exactly the same as the original image, but rather some quality of the image compressed with JPG is lost.

The format has a parameter called quality, which can be altered so that the compression is higher or lower, always being the higher the compression the lower the quality.

JPG is intended to compress photographic images. This means that the images that give the highest quality and best compression when saved in JPG are photographs.

These are images of a certain size, where a large color palette is used and where the colors of a pixel are different from the colors around it.

This graphic format is used primarily on the web, along with GIF. The JPG to save photos and GIF to save drawings.


Announced by Google on September 30, 2010,  a new open standard for lossy compression of 24-bit graphics on the web was born.

The model for this standard was the VP8 video format, developed by the company On2 Technologies and which Google had acquired that same year.

Thereafter, Google expanded the WebP format with features such as lossless compression mode, transparency, and animations.

Chrome has supported the compression format since late 2010, but until now, as with Opera, you've had to assume that many browsers only support WebP on an experimental basis.

According to its own statements, Microsoft is currently working to support it in its own Edge browser.

According to Google, images and graphics in WebP format are roughly 30 percent smaller than JPG files and have the same image quality.

While JPG is based on lossy compression methods, WebP allows both possibilities, i.e. lossy and lossless.

Thanks to this flexibility, the format is suitable for both photographs and small images and graphics.

WebP vs JPG

What Google represents in the world of search engines, JPG is, in the presentation of photographs and large images on the World Wide Web.

It is difficult to imagine a website without this image format. Its biggest advantage is, without a doubt, that JPG saves storage space thanks to its lossy compression.

In this notorious detail, WebP also proves to be more efficient and flexible: on the one hand, Google's format offers, in addition to a lossy compression method, a lossless one.

On the other hand, the saving in storage space for WebP format images exceeds that of similar JPG images.
