Images play a vital role in conveying information, capturing attention, and enhancing user experiences on websites. Over time, technology has given birth to allowing everyone to enjoy faster, more efficient devices, which means website owners need to have faster loading web pages, and overall fast loading images. Enter WEBP images, a modern and innovative image format designed to address these very concerns. In this article, we will explore what WEBP images are, as well as how to upload WEBP images in WordPress.
What are WEBP Images?
WEBP is a relatively new image format developed by Google in 2010, aimed at providing higher compression efficiency without compromising image quality. The name "WEBP '' stands for "Web Picture," and it's primarily intended to improve the performance of websites and reduce image load time.
One of the main advantages of WEBP images is their amazing compression capabilities. In comparison to older more common image formats like JPEG and PNG, WEBP can produce smaller file sizes while maintaining similar or even better image quality. This file reduction method is super important for web developers, as it results in faster page loading, reduces bandwidth usage, and increases overall website performance.
The compression efficiency of WEBP is achieved through the use of advanced image coding techniques. Google combined the VP8 video codec for image compression and the WebM multimedia container format to create the foundation of WEBP. The result is a format that can store both lossy and lossless compressed images, catering to various use cases and image quality requirements.
Lossy Compression
In lossy compression, some image data is permanently removed to achieve higher levels of compression. This results in smaller file sizes but comes at the cost of a bit less in image quality. Lossy WEBP images are more of a benefit for photographs and images where small reductions in quality aren’t as decipherable to the human eye.
Lossless Compression
Lossless compression maintains practically all original image data during compression. As a result, the image quality remains unchanged, but the file size reduction is not as much as in lossy compression. Lossless WEBP images are suitable for graphics, logos, and images where preserving image quality is really important.
What makes WEBP images so appealing is their excellent browser compatibility. Most modern web browsers, including Google Chrome, Mozilla Firefox, Microsoft Edge, and Opera, support WEBP images. However, as a note, it’s essential to include fallbacks for older browsers that don’t support the format.
For best practices, and to ensure compatibility, web developers should use a technique called "image format fallback." This process involves providing multiple versions of an image in different formats, such as WEBP, JPEG, and PNG. The developer should use this in conjunction with HTML and CSS code to serve the appropriate version based on the browser's capabilities. In doing this, most browsers can take advantage of the smaller and faster loading WEBP images, while older browsers still deliver suitable versions.
