Overview
These files are commonly termed as ‘ping' and they store the raster files using lossless compression. It came into existence in order to replace the GIF file format as they both have the ability to show transparent backgrounds. Furthermore, it was an enhanced and improved version of Graphics Interchange format. It supports different types of photos. The first one is palette-based photographs that can either have palettes of 24-bit RGB or 32-bit RGBA colours. Second is grayscale images which may or may not have an alpha channel for transparency. Lastly, there is a full-colour non-palette which is based on RGB/RGBA pictures. There is one limitation of this type. It does not support animation like GIF. Besides this, it is non-patented which means there are no copyright limitations.
Technical description
The expanded features like 8- bit channel for transparency and 24- bit RGB support make PNG more popular. The files stores in this format allow the fading of colours from opaque to transparent which is not present in the preceding format. CMYK does not offer support to this extension as it was developed for transferring of files over the internet, not for professional-quality print graphics. It stores information like textual comments, integrity checks and encoded basic pixels in its extensible structure of chunks. It always starts with an 8-byte signature followed by a series of chunks. A chunk furthermore comprises of four parts- length (4 bytes), chunk type (4 bytes), chunk data (length bytes) and CRC- Cyclic redundancy checksum or code (4 bytes).

Overview
TIFF or TIF is particularly used by graphic artists and photographers to store the raster images. It is very easy to scan and fax under this extension. It offers other features as well like word processing, image manipulation, optical character recognition and DTP (Desktop publishing)- which use page layout software. Earlier it was capable of storing two values of each pixel that is why it was only binary image format but now it can have both grayscale images and colour images. It has become more popular due to its wide acceptance of deep-colour photographs. Besides this, it can also have a vector-based clipping path which comprises of outlines and cropping.
Technical description
The photos have a high quality of graphics as this format supports colour depths from 1 to 24 bits. A single TIFF file can also include header tags which define the geometry of an image like size, definition, image-data arrangement and applied image compression. It offers LZW (Lempel-Ziv-Welch) compression which follows a lossless algorithm to reduce the size of a file. Hence, these files can be edited and saved again without any loss of image quality. It also reserves the information of compression method and by default, the value is one, which means no compression. Furthermore, this format uses 32- bit offsets, which restricts the file size to 4 GiB (Gibibytes). Some variants may also use 64-bit offsets to provide compatibility to large files. It should be noted that every file of this type begins with a two-byte indicator of byte order.
