JXT to FITS Conversion: FAQ

What are JXT files?

JPEG XT is an extension of the classic JPEG standard that layers extra metadata and refinement data on top of an ordinary .jpg image, so legacy decoders still show a usable picture while modern decoders can unlock features like high-dynamic-range (HDR), higher bit depth, alpha transparency, and lossless reconstruction. The format keeps the familiar JPEG codestream but adds “boxes” carrying extension layers, making it backward-compatible yet forward-scalable. In practice, that means a single JPEG XT file can serve everything from quick web previews to studio-quality HDR masters without duplicating assets.

What are FITS files?

The FITS (Flexible Image Transport System) format is a standard format used particularly for storing, transferring and processing scientific images from fields such as astronomy. FITS was first launched as an open standard in the early 1980s and has gone through several subsequent upgrades. FITS files contain not just images, but also data related to photometry and spatial calibration, and information about the origin of the image. Similar formats include FIT and FTS.
