About PAM to HDR Conversion
PAM and HDR (introduced 1985) are both image formats, but they differ in important ways. PAM is a widely used file format. HDR (Radiance) is a high-dynamic-range image format used in lighting and rendering.
When you convert PAM to HDR, the goal is to convert between formats quickly. Converting PAM to HDR maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.
Your PAM file is decoded and re-encoded as HDR. The conversion involves 4 steps: (1) your pam file is uploaded and validated, (2) the file is decoded (parsed into its raw data), (3) the data is re-encoded in hdr 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 HDR file. For the opposite direction, CocoConvert also supports HDR to PAM conversion.
