Can't open the JP2 file? You are not the only one. Thousands of users face similar problems every day. Below you will find tips on how to open JP2 files as well as a list of programs that support JP2 files.

The JP2 file is supported on 3 operating systems. Depending on your operating system, you may need different software to handle the JP2 files. Below is a summary of the number of programs that support and open the JP2 file on each system platform.

What is JP2 file?

A .JP2 file is an improved version of the .JPEG format for specialized applications. It allows the use of lossy and lossless image compression depending on the application. The most interesting information is the fact that the format allows you to independently define the color depth of the file (it is defined in the header). From a technical point of view, it was decided to abandon the discrete cosine transform in favor of using a wavelet. The file can also be in the form of .JPX and .JPF.

How to open JP2 file?

The main problem with JPEG 2000 Core Image Format is that the JP2 file is incorrectly associated with programs. Thus, when you open JP2, the program selection wizard or some other program starts. How to solve such a problem?

The first thing you should do is just "doubleclick" on the JP2 file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Safari

The first step is to check if the computer has the Safari program installed. To do this, enter the name Safari into the system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support JP2 files.

Programs to open JP2 file

Remember to download programs supporting JP2 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Safari with JP2 files

However, it may happen that the application itself does not cause the JP2 file to open in the Safari application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. The "always use the selected program ..." field will set the Safari application as the default for handling the JP2 file.

Step 3. Update Safari to the latest version

If, however, after binding Safari with JPEG 2000 Core Image Format there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Apple, Inc. page and install.

Step 4. Check for the following problems with the JP2 file

Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This suggests truncating the JP2 file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the JP2 file that we want to open. As a result of the scan, sometimes it is not possible to recover JP2 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the JP2 file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged JP2 files. The easiest way is to restore the file from a backup, if there is one, or contact Joint Photographic Experts Group
The program can also signal the fact of encryption. The encrypted file JP2 except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. Copying the JP2 file to another location will fix the problem.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes you have to wait for the session to the file JP2 to close. However, some background programs may block the JP2 file while scanning. If the problem persists, restart the machine.
