Its been 2 years since the format was announced in September 2010 and Google aims to make the Webp format as a new open standard for lossy and lossily compressed true-color graphics on the web . The webp image format is not much popular right now . My encounter with the webp format happened when i was trying to save a few app screenshots from the Google play store . I was surprised to see the new image format . With Curiosity i tried to find out about the Webp image format and here is what i could find out . lets start with what Google describes webp as .

What is webp ?

WebP is a new image format that provides lossless and lossy compression for images on the web. WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller in size compared to JPEG images at equivalent SSIM index. WebP supports lossless transparency (also known as alpha channel) with just 22% additional bytes. Transparency is also supported with lossy compression and typically provides 3x smaller file sizes compared to PNG when lossy compression is acceptable for the red/green/blue color channels.

The above quote from Google provides a lot of information about the Webp image format .

Recently Facebook tried to switch over to the Webp image format for all the image content on its site  . Surprisingly it was not a good move , as it did cause a lot of upset among the Facebook users . users who tried to download images from Facebook were left puzzled . The cause being webp is not supported by most operating systems like windows , Mac  and image editing apps including the very popular Adobe Photoshop . overall it was a good thing , as criticism will help to improve a new image format like webp .

Once webp become a standard image format we can experience faster website loading speeds and the best part is , The data transfer will decrease too .
