PNG – is a scan-line graphic format developed as an alternative to GIF, a commercial license. However, they are both raster image types. PNG is based on the best features of the predecessor, including lossless compression and transparent background support. The PNG technology ensures the preservation of all stages of editing and the restoration of the step by preserving the quality. However, it does not allow us to save several pictures in one file at once, limiting its use in the development of animated images.

The PNG extension was proposed as a tool that helps to transfer and store images on the World Wide Web. The technology is limited to an 8-bit transparency channel so that you can adjust the colors from opaque to transparent. It supports 24-bit RGB colors, matching images, and shades of gray. However, as a non-professional format, PNG can not display other color spaces. Most programs allow you to open such files. They can also run in any browser. Images are different in small weight with good quality.

Google developed the WEBP image format in 2010. According to their claim, this format can save files up to 34% smaller than the JPEG or PNG files. It allows saving images in both lossy and lossless compression. Yet, it is not supported by all image viewers.

Lossy compression in this format is obtained by prediction. In this compression, an image is divided into some blocks, and predictions are made depending on the surrounding blocks' pixels. Here the difference between the main image and the forecast is recorded by encryption. The prediction is good enough to ensure no difference according to the actual image. It reduces the file size. Lossless compression is gained by the pieces of the image previously examined to Build the rest of the picture.
