About HDR to JBG Conversion

HDR (introduced 1985) and JBG are both image formats, but they differ in important ways. HDR (Radiance) is a high-dynamic-range image format used in lighting and rendering. JBG is a widely used file format.

When you convert HDR to JBG, the goal is to convert between formats quickly. Converting HDR to JBG maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.

Your HDR file is decoded and re-encoded as JBG. The conversion involves 4 steps: (1) your hdr file is uploaded and validated, (2) the file is decoded (parsed into its raw data), (3) the data is re-encoded in jbg format, (4) the converted file is ready for download.

CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.

This conversion is ideal when you When you need a JBG file. For the opposite direction, CocoConvert also supports JBG to HDR conversion.
