Online Radiance HDR to JPG Converter

Convert Radiance RGBE (.hdr, .pic) high dynamic range images and 360° environment maps into standard 8-bit sRGB JPEG images. Created by Greg Ward for the Radiance lighting simulation system, the .hdr format stores linear floating-point luminance using an 8-bit Red, Green, and Blue mantissa plus a shared 8-bit Exponent byte (32 bits per pixel), enabling a dynamic range spanning dozens of f-stops.

Converting 32-Bit RGBE to 8-Bit sRGB

Because .hdr files store linear scene-referred radiance values, web browsers and standard image viewers cannot display them directly. Our converter decodes the RGBE mantissa/exponent channels, transforms the linear light data into the nonlinear sRGB color space (-colorspace sRGB), and normalizes the dynamic range (-auto-level) so your skybox, equirectangular panorama, or studio light probe can be previewed and shared as a regular JPEG.

How to Convert HDR to JPG

  1. Upload your .hdr file from your device or paste an image URL.
  2. Set the JPG quality slider (1–100, default 90).
  3. Click "Convert to JPG!" and download the sRGB JPEG image, or resize your panorama using our image resizer.
