The WebP is a new technology in the image file compressing which allow you to store the image at 26% smaller size compared to
the PNG image without losing the quality. The Webp to JPG image formats are 25-34% smaller in the size compared to JPEG images. It allows website
owners to use smaller size mages on the site to give faster website experience to their users.
The Webp image also supports transparent file format and provides the image at 22% additional bytes per image. If we compare with the size of the PNG file, then it will be 3x smaller than PNG.
The Lossy WebP to JPG file compression technology uses completely different way to render the code of the images. It predicts the common coding of the image to get the information of the particular image. This is similar to how VP8 video codec compresses key frames in videos. In the prediction process, the image is using the neighbouring blocks of pixels to predict the values in a block and then return only the difference. This enables the image to get some part of the codes from the neighbouring source and only collects the unique information from the new image. The process saves the time to download the image information from the source and present the image from the fastest channel.
In the Lossless WebP image, it represents the file using a part of the already available image in order to recreate the new
pixels. Sometimes it uses the local palette if no relevant match found while serving the image information.
The WebP file uses VP8 or VP8L image data and a container based on a RIFF. The libwebp library is published in the git repository which works as a reference point for implementing WebP.
Currently, the Webp is supported by Google Chrome and Opera browsers. Many other tools and software libraries have started opting the Webp based files. Many image editing tools also started implementing the webp based images to their software.
WebP to JPG comes with fully develop a lightweight library which allows you to encode or decode certain images by using command line tools like cwebp and dwebp. You can convert the image into webp format by using this command line. It is also useful for viewing, animating and muxing the webp images. The full source code is available on the download page at git repository.
The JPG images files are most used on the website. The JPG is most popular image format because of its low size capability and fast rendering quality. The Webp file format takes the image optimization technology one step further. The Webp image technology uses common predictive code that it collects from the neighboring file to process the image faster. The Webp image file formats are approx 34% less than normal JPG image file.
There are several tools available in the market to convert your normal JPG file into a webp based file. You can Google it to find some of the best available image converting too in the market supporting Webp to JPG images.
At this movement, the only small percentage of the website adopted the new webp format images. Google has already started implementing the webp file format on the YouTube thumbnail. They saw 10% increases in page speed after implementing. Google wants to make the web faster, and the webp images are serving the purpose. Google will be using the webp format on other product also once all the top browsers and operating systems start using the webp format.
The Facebook is also running the webp images on the android Facebook app. They are testing the user experience to
understand how much difference it will create in the mobile app.
Since Google and Facebook have adopted the new image technology, it seems other websites will thrive on implementing it on their website.
The big concern for the image is the loss of the quality. Especially the photographer communities are concern about the drop in the high-resolution image quality. Generally, when you compress the images to reduce the size of the image, it ends up losing the quality of the image. The image pixel starts looking blur and kills the overall image experience. Its a nightmare situation for the photographer. Webp to JPG converts the image in the moderated file format which keeps the image in the high-quality format while reducing the file size. As webp takes the common codes from the neighboring file, it will not compromise the image quality. All codes are used as it is by just changing the way it collects the code.
PNG is known for its high-resolution image quality and the transparent image format. The developer generally prefers using the png image when it requires detailed images without compromising the quality of the image. The PNG is not suitable for the web pages. The size of the png file increases the time it takes to load each png image file. Not suitable for the fastest internet browsing experience. This is where the Webp image format comes in place. The webp images can generate lossy or lossless images for the web pages. You can also convert the image into the transparent background as png offers. This makes the webp image format flexible enough to operate in both the condition. The webp can serve as an alternative to your png and jpg file. The best thing about webp image is you get the compressed image without compromising the quality.
Today storage has become big challenging for the big websites like Google and Facebook. The fraction of the decrease in the image size can impact at a big level in the image storage system. It will take the storage cost down to millions of dollars. That's why Google has opened source the technology for the general people so they can start implementing it on their website which eventually helps Google to store fewer data in their server storage. Some websites have already started implementing the webp images on their site. It has seen the benefit of the webp images is spreading out in the community and people are seeking to implement it on their website.
Webp image file format is a great piece of the technology available in the market. Everyone should start implementing it to reduce the server size and bandwidth. Soon WebP to JPG, PNG files will become a mainstream technology that you will find everywhere on the web.
