| Overview |
| This file extension is capable of storing only monochromatic images that are black and white. This format has become now outdated and it was used by early mobile phones for exchanging and storing the monochromatic pictures that were sent using SMS messaging service. The successor to this is PNG which supports colours. As mobile phones have come up with improved and enhanced features that is why this format has been largely replaced by full-colour image and video formats. This extension has many likenesses with BMP files that is the standard bitmap images. WBMP does not support grayscale images as well as colour images. The size of the file is small and is always kept in reduced size. |
| Technical description |
| In this WBMP format, pictures are created by using pixels in which 0 (zero) is assigned to black pixel and 1 (one) is for a white pixel. There are certain fields which are present in this file extension. The field names are as follows along with their purpose. The first one is type, it tells about the type of an image and zero is fixed for monochrome bitmaps. The next is a fixed header and it is always reserved with 0 value. Then comes the width and this defines the breadth of an image in pixels. The second last is the height and it represents the height of a photo in pixels. The last one is data and it tells about the data bytes arranged in rows. |

| Overview |
| 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. |
| Technical description |
| 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. |
