Have you encountered a problem with a JPEG file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a JPEG file here. In the further part of this page we have added a list of programs that should open your JPEG file. It is enough you choose a proper application for your operating system, download and install it.


A JPEG 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.

JPEG 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.

JPEG 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.

JPEG is not suitable for line art and rasterized images such as newspaper images. Here the losses due to the compression are immediately obvious.

Jpeg files can 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, jif, jfif and jpe. If the extension of the file is not recognized directly, it can also be changed to one of the others.

Every current operating system today contains an image viewer that can display JPEG files. There is also a large number of free or commercial programs.

How to open a JPEG file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the JPEG file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a JPEG file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support JPEG files. At this point we are looking for disk space where the application was installed in and we can link it with a JPEG file. Since then, our operating system will use the selected program to support all JPEG files.

Other issues

Despite the described problem with JPEG there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the JPEG file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the JPEG file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
