About RLE to HDR Conversion
RLE and HDR (introduced 1985) are both image formats, but they differ in important ways. RLE is a widely used file format. HDR (Radiance) is a high-dynamic-range image format used in lighting and rendering.
When you convert RLE to HDR, the goal is to convert between formats quickly. Converting RLE 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 RLE file is decoded and re-encoded as HDR. The conversion involves 4 steps: (1) your rle 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 RLE conversion.
