JPG to JP2 for Archives, Publishers and Libraries
Some archives, publishers and library systems still specify JPEG 2000. This free JPG to JP2 converter encodes your .jpg images to lossless .jp2 entirely in your browser with the OpenJPEG engine — no installs, no uploads, no accounts.
True Archival Format
JPEG 2000 is the preservation standard for national libraries and archives. Your converted files meet that specification, encoded losslessly.
Lossless Encoding
The JP2 stores your JPG's decoded pixels exactly — converting adds no further quality loss beyond what the JPG already had.
Honest Sizing Note
Lossless JP2 of a photo is usually larger than the lossy JPG it came from — that is the nature of lossless. JP2 is chosen for preservation and specification compliance, not for shrinking photos.
