WebP is a modern raster image file format created by Google that makes lossy and lossless compression for web based images.
This means you can either compress images without losing data or with losing only some non-essential info.
The WebP image can be identified by looking at the .WEBP extension for images
WebP keeps the same image quality while notably decreasing image size. Because most websites use images to effectively represent data, using WebP images in web pages results in faster page loading, compared to PNGs, with 26% less in size.
As per Google, WebP lossless images are 26% smaller than PNGs, and WebP lossy images are 25-34% smaller than equivalent JPEG images.
The Structural Similarity (SSIM) index is used to compare images between WebP and other image file formats. WebP is the multimedia container format WebM’s sister project.
The structural similarity index measure (SSIM) is a method for predicting the perceived quality of digital television and cinematic pictures.
The WebP file’s history.
WebP is a relatively new format, found in 2010. The original concept was developed by On2 Technologies, a firm acquired by Google.
Every WebP file has VP8 or VP8L image data. The format has evolved over time based on change in consumer behaviours and rising digital trends.
In 2011, Google introduced functionality for motion and transparency, and the format is now interoperable with web browsers other than Google’s.
Google Chrome, as well as Firefox, Edge, and Opera, natively support WebP. It however, suggest web developers to first convert PNG and JPEG files to WebP, to improve page load time.
How to Work with WebP Files?
WebP files were created with the internet in mind. Their primary use include:
Reducing the size of webpage images.
- WebP strives to strike a compromise between quality and usability.
- WebP files use predictive coding to compress photographs and graphics while keeping their visual quality in smaller size, reducing pressure on user broadband connection and make website faster to traverse, resulting in a better page experience.
Online animations are supported.
WebP files are an alternative to GIFs, preferred format for memes and other basic web animations till now. An animated WebP, as per Google, can be considerably smaller than a GIF, requiring less bytes.
