Convert SVG to WEBP

WebP is a file format which uses both lossy and lossless compressions to encode the files. It was developed by Google in order to facilitate the work online which can be done quickly and easily with this extension. This is a sister project of WebM Multimedia container and it produces high quality of images. It is claimed that it can reduce the file size by 34% without affecting the quality of a photo. Due to this reduced size, online work can be done in less time as these files can offer high speed over the Internet due to small size. This format provides add-on support to the lossless algorithm, metada, transparency, colour profile and animation.

Intra frame coding that is used in video format and the resource interchange file format, are base for its lossy compression. Only 16,383 pixels can be used to represent the side length of an image. Besides this, it is based on block prediction in which every block is forecasted as per the values, from the three blocks above it and from a one block to the left of it. Horizontal, vertical, DC (one colour) and Truemotion are the four basic modes of block prediction in this extension. Animated images can also be produced using WebP and this is a substitute to famous GIF format. It comes with many improved features. For instance, 24 – bit colour with transparency, joining of frames with both lossy and lossless compressions in the same animation and providing support to seek to a specific frame.

This extension is based on an extensible Markup Language (XML) and images stored in this format are two dimensional as well as vector graphics. It is an open standard format but it supports both interactivity and animation. These files can be searched, indexed, scripted and compressed because their behaviour is specified by XML text files. Editing can be done using a text editor or any drawing software. All popular web browsers provide rendering support to SVG. The major difference between the bitmap image or raster image and vector image is that the former one is made up of a fixed set of pixels whereas the latter one consists of a fixed set of shapes. Scaling in raster reveals the pixels in it and in vector it tells about the shapes.

It follows lossless data compression as it contains numerous repeated fragments of text. SVGZ image is a compressed form of SVG, when it is compressed using GZIP algorithm. In 2011 there was mobile version 1.1, which minimized the computational and display capacities. As these files use text to describe the graphics that is why it is very easy to resize them to different sizes(Zooming and Diminishing) without loss of quality. Besides this, they have the capability to store rich graphics and also offers compatibility to CSS(Cascading style sheets) for styling which in return allows a higher level of presentation editing. In addition to this, JavaScript is used for scripting. Lastly, it has three types of graphic objects – vector graphic shapes (paths and outlines), bitmap images and text.
