JPEG is probably the most popular extension for storing and transferring images. Many users prefer this format for sending photographs by email or uploading them on social networks. The reasons are obvious: JPEG can be opened with even the most basic image viewer, provides small size and decent image quality.
The format is also used as output extension by many scanning and faxing devices. Using JPEG you can get a quick and small digital copy of a document. As this is a raster format, however, what you get is an image reproduction of the document. Not an actual text. This means scanned JPEG cannot be searched or edited. Depending on your area of work, this can be a considerable problem. For example, if you scan a certificate or an invoice that you need to make quick corrections to, the JPEG format will not be of much help.
