What is JP2 file?
A JP2 file contains a bitmap image in JPEG 2000 format. The core coding procedure was used.
More info
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. Unlike JPEG, this metadata is not in EXIF format, but JPEG 2000 stores the same data as XML. Adobe's Extensible Metadata Platform (XMP) is also supported as a metadata format.
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.
There are different versions of the JPEG2000 standard, not every program supports them all. Different programs also need a plugin to handle JP2 files. Jp2 files usually contain data in the first standard (Part 1) of the JPEG 2000 format.

How to open file with JP2 extension?
Install Safari or other program from the list
Most often resolving problems with opening JP2 files is very simple. Just install an appropriate program that supports such files. All of the listed programs support JP2 files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of JP2 files or offer file conversion options, but may not be capable of editing such files.
Set Safari as the default program for opening JP2 files
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate JP2 files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the Safari applications is not on the list, select "Browse" option in order to manually locate the directory where Safari has been installed.
Check the section that lists most common problems with JP2 files
Sometimes problems with opening JP2 files may not lie with the application itself, but can arise due to other causes, such as:
- File data is corrupted
- JP2 files has been not been completely download from the internet (only a part of the data has been downloaded)
- Currently used user account hasn’t been granted necessary privileges to open JP2 files (should that be the case, please contact your system administrator or IT specialist)
- JP2 file was being copied from a corrupted storage device and is incomplete or data is corrupted. (Copying files from unknown or untrusted sources should be conducted with great care as such files may contain malicious software, which can damage your system)
