A JIF file contains bitmap image data in JPEG format. This format is produced by most digital cameras and is the most widely used format for pictures on the Internet. Jif files are much smaller than comparable image formats. This is achieved through the use of lossy compression. As the compression rate increases, these losses become visible and are noticeable by image noise and blocks in the image. With low compression, also referred to as high quality, these losses are barely noticeable despite the significantly smaller file size.
JIF files can not contain transparency information. They are also not suitable for further image processing, since the losses of image information when repeatedly storing an image add up. This means that even when using a quality of 100% and thus the least compression, the noise in the image increases with each saving.
The JPEG format is not suitable for line art and rasterized images, such as newspaper images. Here the losses due to the compression are immediately obvious.
JIF files may also contain so-called metadata. These are usually stored by digital cameras. You can include a lot of information about the picture. From the camera's data, exposure time and aperture, to the GPS location information of the location where the photo was taken.
JPEG data is also included in files ending in jpg, jfif, jpe and jpeg. If the extension of the file is not recognized directly, it can also be changed to one of the others.
Each current operating system today contains a picture viewer that can display JIF files. But there are also a large number of free or en programs.
Most often resolving problems with opening JIF files is very simple. Just install an appropriate program that supports such files. All of the listed programs support JIF files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of JIF files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate JIF files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the Apple Preview applications is not on the list, select "Browse" option in order to manually locate the directory where Apple Preview has been installed.
Sometimes problems with opening JIF files may not lie with the application itself, but can arise due to other causes, such as:
