How the WebP Image Format Helps Optimize Product Images for Websites

As a marketing manager, you are constantly faced with the challenging balancing act between exciting creatives and small, fast-loading formats. Especially if you are responsible for presenting many products and their variations in an online shop, you know how quickly numerous media can accumulate and slow down the loading time of product pages, potentially even overstretching the patience of potential buyers. 

To optimize the performance, size, and loading speed of your e-commerce shop for the benefit of your buyers, it is always worthwhile to stay informed about technological innovations and to try out new possibilities in a timely manner.

This is where the WebP image format, developed in 2010, comes into play.

WebP is the open-source answer of internet giant Google to the selection of existing, older image formats. The innovative image format aims to help website managers reduce media storage space in the long term without compromising the user experience.

What is the WebP image format?

WebP is a compact image format that offers excellent compression and quality for the web compared to other image formats, such as JPEG and PNG. What is particularly interesting is that this image format was explicitly designed and developed for the web to reduce the size of images without sacrificing quality. This characteristic makes WebP an ideal choice as an export format for product images in e-commerce or online shops.

WebP images come in two varieties – lossy and lossless. Lossy WebP images are highly compressed, making them smaller while still maintaining good image quality. Lossless WebP images also offer better compression without sacrificing image quality.

Both variants can actively help to significantly improve the weight and performance of your website for your "impatient" users, without compromising the image quality of your website. Not to mention, your website can load faster with smaller product images, thus making it better suited for common search engines and their quality criteria for a "good website."

How can using the WebP image format improve my website performance?

The file size of a product image is an important factor for a high-performing product page. With the growth of the digital world, usable image formats for product images have also evolved; knowing and utilizing the right image format can therefore make a big difference. 

As a relatively new image format, WebP promises to reduce your image file size and improve website performance. But what are the advantages and disadvantages of this new image format, and how does it differ from older formats like JPG or PNG?

Comparing the WebP image format with other image formats

To categorize the power of the WebP image format - such as better compression and compactness - within the format landscape, one must consider the WebP image format in comparison to other common export formats like JPG and PNG.
