JPEG XR / HD Photo — stored as image/jxr — uses lossy encoding to handle hdr imaging, windows photo ecosystem, lossless hd photo archival. Typical file sizes: varies by content.
Portable BitMap (PBM) is a simple monochrome image format that stores each pixel as either black or white in an ASCII text representation.
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 PBM when your priority is simple image processing, scientific visualization — its uncompromising quality ensures every detail is preserved.

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