5 Best Free JP2 Viewer Online Websites

Here is a list of the best free JP2 viewer online websites. JP2 is an image file format that uses JPEG 2000 image compression standard. It is also known as JPEG 2000. This file format is developed by the Joint Photographic Experts Group (JPEG) committee. It provides advanced features over the original JEPG format. It is originally designed to replace the JPEG but it hasn’t caught the popularity yet.

JP2 supports lossy as well as lossless compression. It can store multiple quality layers within a single file that enables progressive loading. It can also store various types of data including grayscale, RGB, etc. Unlike the original JPEG, it can also support transparency. JP2 image files are commonly used in digital photography, satellite imagery, medical imaging, etc.

Most image viewer software and apps do not support JP2 files. To be able to open a JP2 file, you have to find a tool that supports the file format. Alternatively, you can use an online JP2 viewer to view a JP2 file. An online viewer is safe and easy to view the file quickly. There is no download or installation required. This post covers 5 free online viewer websites where you can open and view JP2 files.
