About JP2 Files

.jp2 Icon

A .jp2 file is a JPEG 2000 image file, designed for high-quality digital photos. This format was created to replace the original JPEG standard but never caught on due to its slow and memory-intensive editing process. It supports both lossless and lossy compression.

JPEG 2000 files are viewable by most image editors but aren't as well-supported by web browsers. Converting one to JPEG (.jpg) will make it easier to share, although there may be some quality loss when converting from a lossy JP2 to a lossy JPEG. Converting to a lossless format like PNG (.png), bitmap (.bmp), or TIFF (.tif) will preserve all of the image data, but at a higher file size.
