Overview
PDF is a format which stores documents that can include text with distinct fonts and images. The text that is present in it is of static or fixed format which is just like an image and it remains exactly the same even if we open this file using other programs, hardware and different operating systems. That is why it is recommended to convert the file into this format before printing or transferring, so, that the arrangement of the lines remains the same. Thereby, the output that is generated is always a printer-ready. These files are editable and can be amended using various editors. Several files can also be merged and compressed online. It does not only support Adobe Acrobat Reader but also other similar programs. These files can be sent, saved and viewed easily using phones, computers or tablets.
Technical description
There is a vast horizon of features that are available in PDFs. The content in it can have logical structuring elements, annotations, rich media, digital signatures and 3D computer graphics data (U3D); etc. Although, it is a 7-bit ASCII (American Standard Code for information interchange), yet, it may contain binary content as well. This file starts with a header which indicates how bits are used to encode information, succeeded by the version of the format. Furthermore, it is a subset of COS i.e. Carousel object structure, which expands to eight primary objects named as- Boolean Values (true or false), numbers, strings, names, arrays, dictionaries, streams and the null object. These files can also be password protected for security reasons.

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.
