About JPEG 2000
JPEG 2000 replaced the blocks of a regular JPEG with wavelets, which blur gently instead of breaking into squares. It can be lossy or perfectly lossless, and it handles very large images and high bit depths.
It never took off on the web, but it's everywhere else: digital cinema, medical scans, scanned books in library archives, satellite and aerial imagery, and images inside PDF files.
Safari was the last browser to show JPEG 2000, and version 18 dropped it. Filepeek decodes it itself, transparency included, so .jp2, .j2k and .jpx files open in any browser.

Questions
Why won't my browser open JP2 files?
Safari was the only browser that showed JPEG 2000, and version 18 removed it. Filepeek brings its own decoder, so it opens in Chrome, Edge, Firefox and Safari.
What are .j2k and .jpx files?
Other forms of JPEG 2000. A .j2k or .j2c file holds the bare image data, and .jpx is the extended file format. Filepeek opens them all.
Is my image uploaded?
No. The decoder runs in your browser, on your device.
Can I convert JPEG 2000 to PNG or JPEG?
Yes. Open it, choose Export, then Save as PNG or Save as JPEG.
