WebP image format was proposed as an alternative to JPEG, with 25-34% better compression compared to JPEG images at equivalent SSIM index — today, reveived a new mode to compress images “losslessly, and support for transparency” – also known as alpha channel – in both the lossless and lossy modes.
“With these new modes, you can now use WebP to better compress all types of images on the web,” revealed Chromium team.
Last month, Google added new features to WebP such: animation, ICC profile, XMP metadata, transparency and and tiling.
“Photographic images typically encoded as JPEG can be encoded in WebP lossy mode to achieve smaller file size. Icons and graphics can be encoded better in WebP lossless mode than in PNG. WebP lossy with alpha can be used to create transparent images that have minimal visual degradation, yet are much smaller in file size. Animations compressed as GIFs can use animation support in WebP,” the Chromium team explains.
“WebP is a new image format that provides lossless and lossy compression for images on the web. WebP lossless images are 28% 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 losseless transparency (also known as alpha channel) with just 22% additional bytes.”
WebP is the one-size-fits-all solution that can replace all the other image formats. Unfortunately, it’s only supported by Chrome, Opera and Android’s browser (Ice Cream Sandwich).
You can also install the WebP image codec in Windows, use image editing software that supports WebP (GIMP, ImageMagick and more) or install a Photoshop plugin.
Now you can also find WebP images using Google’s image search engine. Just add filetype:webp to your query or go to the advanced search page and select “WebP Files” in the “File types” section. Here’s an example.
If you restrict the results to .com domains, Google only returns 1830 WebP images. There are 115 results for [Google], 7-9 results for [webp] and 88 results for [image].
