Overview
Files stored in this format are small in size that is why they can be uploaded and downloaded with ease. It takes less time over the internet to upload and download due to smaller size which results in saving of bandwidth. This extension is compressed using a lossy algorithm that is why there can be a reduction in the quality of the photograph. It has the ability to compress the file to one-tenth of its original size. It is widely used in emails and also when images are to be posted on websites. Digital Cameras and other photographic image capture devices widely use this JPG format. The paintings and photos of realistic scenes that have smooth variations of colour can be best illustrated by this format.
Technical description
A technique used in JPEG format to compress files is lossy compression which is based on DCT (Discrete Cosine Transform) as it is the most practical Mathematical operation. The DCT actually converts each frame of the video from the spatial domain to a frequency/transform domain. It discards the information of high frequency that has sharp transitions in intensity as well as in colour hue. Furthermore, this standard defines a codec which tells how an image can be encoded into a stream of bytes and decoded back into an image. The files can be compressed in the ratio of 100:1 but that would result in the poor quality of an image. Therefore, to retain the quality of a photo, a file should be compressed till 20:1 ratio not more than that.

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.
