What is JPEG file?

JPEG file extension is commonly associated with image files, and is one the most popular graphic formats currently in use. It uses lossy compression algoritm designed by Joint Photographic Experts Group. JPEG files are usually used to hold digital image data and computer graphics. JPEG file contains metadata with additional information such as color space, color profile, and image dimension.


JPG file extension, a format that is interchangeable with JPEG, is the more popular format of the two.

JPEG compression method

JPEG uses lossy compression algorithm, i.e. some image information is lost and cannot be recovered. Although such compression method significantly reduces image size, it comes at the cost of lower image quality. Still, JPEG offers acceptable image quality despite drastic reduction of file size. Furthermore, user can choose compression level while converting image into JPEG to achieve desired quality.

JPEG format specification

JPEG file stores up to 24 bit s of data per pixel, which means it supports full color pallete. JPEG format is further divided into 2 sub-formats – JPEG/Exif and JPEG/JFIF. The former is used in photography, while the latter is the internet standard. Exif and JFIF standards define the popular JPEG-compressed image format.

Conversion of a JPEG file

When you install one of the applications from the list of programs that you found here, you should be able to open or edit the file with the JPEG extension without any issue. However, if you still have problems with this, you may use the option of JPEG file conversion to a different format.

We hope we helped you solve the problem with the JPEG file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

There can be more reasons which determine that you are not able to open the JPEG file (apart from the lack of the proper application installed).

First - the JPEG file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the JPEG file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the JPEG file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the JPEG file has not been completed and it cannot be opened properly).
