What is a WebP file?

WebP (pronounced The Weppy format (1

9459007) is the sister project of the WebM video container format, based on the VP8 video codec developed by On2 Technologies and published by Google, Google acquired On2 Technologies on 19. February 2010 and WebP published in September of the same year.

With 60 to 65 percent of the bytes on most web pages being images, Google set about creating a free open source file format that would be lossy as well as lossless Save high-quality compression formats, while maintaining quality and reduced image size, load pages faster, use less bandwidth, and conserve battery power when using WebP images, especially on mobile devices.

WebP uses predictive compression to encode a picture. the values ​​in neighboring images are checked for pixel blocks to get the values ​​in a blo to predict, and then encodes only the difference between them. In this way, pixels can be copied multiple times into a single file, and redundant data is removed from each block. Saving only the data that changes between blocks reduces memory space compared to PNG and JPEG formats. For more information, see the official webpage for WebP compression techniques.

Lossless WebP images are 26% smaller than PNG files and up to 34% smaller than lossy JPEG files with an SSIM (Equivalent Structural Similarity) quality index.

How do I open one?

Since WebP was developed by Google and royalty-free, it has already been integrated into many applications and applications software that you may already have installed on your computer. Most web browsers already have the plug-in required to process the format.
