Have you encountered a problem with a JPC 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 JPC file here. In the further part of this page we have added a list of programs that should open your JPC file. It is enough you choose a proper application for your operating system, download and install it.


A JPC file contains bitmap image data in JPEG 2000 format. However, it only contains the code stream, ie only the data stream that contains the pure image data.

JPEG 2000 describes both a compression method, and thus a codestream (data stream) as well as a file format. While the data stream is sufficient to decode the image, the file format includes additional information such as metadata.

JPEG 2000 is a digital image compression technique that provides both lossless and lossy compression. It has some advantages over JPEG. Image quality is better at high compression rates and some limitations no longer exist. Eg image size, color depths or support for alpha channels (for transparency). However, this is offset by the licensing-related situation and a significantly higher demand for computing power.

The pure data stream (codestream) is not intended to be stored in files, so no uniform extension is required. The endings jpc, j2c and j2k are common.

There are different versions of the JPEG2000 standard, not every program supports them all. GIMP needs a plugin to handle JPC files.

How to open a JPC file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the JPC 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 JPC 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 JPC files. At this point we are looking for disk space where the application was installed in and we can link it with a JPC file. Since then, our operating system will use the selected program to support all JPC files.

Other issues

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

- verify that the JPC 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 JPC 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.
