JXT to PGM 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 PGM files?
The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
