About HD Photo / JPEG XR Conversion
HD Photo (JPEG XR) was Microsoft's attempt to succeed JPEG — better compression, HDR support, and lossless mode. Despite shipping in Windows and being standardized as ISO/IEC 29199-2, it never reached the web: Chrome, Firefox, Safari, and Edge all lack native .jxr support. That leaves anyone with Windows-generated .jxr/.wdp/.hdp files — including the growing number of OBS HDR screenshot users — with files nothing can open. This converter decodes JPEG XR locally via a WebAssembly build of the reference jxrlib and re-encodes to universally supported JPG.
Expert Tips
- Keep quality at 90% for screenshots — text stays crisp while file size stays reasonable
- If an OBS .jxr looks washed out after conversion, your display is SDR; the JPG conversion maps HDR values to standard range
- Convert in batches of 10 to keep browser memory usage low when processing screenshot folders
- The .wdp and .hdp extensions are older names for the same format — all three decode identically
- JPG discards transparency. If your HD Photo has an alpha channel, expect a white background in the output
