JPEG2000 is a wavelet-based image compression standard. The standard includes a number of file formats that are used as containers for compressed image and video data:

• JP2 JPEG2000 Part 1 (base still image format)
• JPX JPEG2000 Part 2 (extended still image format)
• JPM JPEG2000 Part 6 (compound image format)
• MJ2 JPEG2000 Part 3 (motion JPEG2000)
• J2C JPEG2000 codestream (also defined by Part 1)

Disambiguation

Colloquially the denomination JPEG2000 is sometimes used to indicate the JP2 format. This is not strictly correct, as JPEG2000 is a compression standard, not a format. It is also confusing, since the JPEG2000 standard comprises multiple file formats.
