Read a JP2 File's Header Without Special Software
JPEG 2000 files store their key facts in header boxes most software never shows you. This free JP2 metadata viewer parses the jp2h, ihdr and colr boxes locally in your browser — dimensions, component count, bit depth, colour space — and verifies them with a full decode.
True Header Facts
Facts come from the file's own header boxes, not guesses: width, height, components, bits per component and enumerated colour space.
Decode-Verified
The viewer also decodes the image with OpenJPEG, so what you see confirms what the header claims.
Raw Codestreams Welcome
Files that are pure codestreams (.j2k style) have no header boxes — the viewer says so plainly and still verifies the image by decoding it.
