How to convert JPG to WebP quickly and successfully?

What are JPG and WebP Image Formats?

Joint Photographic Experts Group introduced JPG format in 1992. The popular JPG (Joint Photographic Experts Group) picture file format supports up to 24 bits, which shows up to 16 million colors, and lossy compression.

In 2010, Google introduced WebP, an open standard for the lossy compression of 24-bit graphics on the web. This format, called WebP, was based on the VP8 format. It was made by On2 Technologies, a company that Google bought in the same year. After that, Google added things to the WebP format which include features like lossless compression mode, 8-bit alpha channel, and animations.

Why Convert JPG to WebP?

Web and app developers prefer the WebP image format when they upload many images. WebP images have smaller file sizes than JPG images. This helps websites load faster. Faster websites give a better experience. Google also prefers fast websites. So, websites with WebP images rank better in search results. Developers use WebP to improve page speed and SEO.

E-commerce business owners also use WebP images. They want their product images to load quickly. When images load fast, customers see products without delay. This helps reduce bounce rates. Bounce rate means the number of users who leave the site quickly. If the site loads slowly, users do not wait. They leave before seeing the products. But fast websites keep users on the page. More users stay, view more products, and buy more items. So, WebP images help increase customer conversions. JPG images are larger and load slower, which affects user experience.

WebP also works with modern web browsers. These include Chrome, Firefox, Edge, and Opera. Developers like this because most users use these browsers. WebP shows images clearly and quickly in these browsers. But older browsers, like Internet Explorer, do not support WebP. For this reason, developers sometimes add JPG as backups. This way, all users see the images, even if their browser does not support WebP.
