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


The file extension JPM marks a bitmap image in the extended JPEG 2000 format. There are several enhancements of the JPEG 200 standard, which open up additional possibilities. The support for the extensions is not yet widespread and does not have to be complete for a program.

The extension JPM identifies files that contain composite JPEG 2000 images. These consist of several levels that have been coded with different methods or emphases in the presentation. In addition, the files include a mechanism for composing the images and 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.

Some programs require a plugin to support the format.

How to open a JPM file? Advice and guidance

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

Other issues

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

- verify that the JPM 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 JPM 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.
