JXR files are built around lossy compression. Designed for hdr imaging, windows photo ecosystem, lossless hd photo archival, they use the image/jxr MIME type and typically range from varies by content.
Portable AnyMap (PNM) is a super-format that encompasses PBM, PGM, and PPM image types for simplified image processing.
Reach for JXR when your priority is hdr imaging, windows photo ecosystem, lossless hd photo archival — its efficient compression makes sharing fast and storage minimal.
Reach for PNM when your priority is cross-format image processing, netpbm suite — its uncompromising quality ensures every detail is preserved.

No, converting JXR to PNM does not cause additional quality loss — PNM uses lossless compression. However, any artifacts already present in the original JXR file will persist in the PNM output.
PNM files are typically 2-5x larger than equivalent JXR files because PNM preserves all pixel data. This is expected and necessary for lossless quality.
Yes, PNM supports transparency. Alpha channel information from JXR is preserved during conversion.
