FAQ

J6I to JP2 Conversion

What are J6I files?

J6I is an image format associated with digital photos shot using Ricoh cameras. Ricoh represents a Japanese brand with a history of over 70 years, particularly known for producing printers, fax machines, digital and film cameras and other electronic products. J6I is a proprietary format for Ricoh cameras and might not be recognized by most regular image viewers, so it's probably best to convert it to JPG or PNG for better accessing and transferring options.

What are JP2 files?

JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images. Compared to the latter, JP2 image files offer higher quality and smaller size images by using a different compression algorithm, which can be either lossy or lossless. JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.
