Online Radiance HDR to PNG Converter

Convert Radiance RGBE (.hdr) high dynamic range files into lossless PNG images. Used across Blender, Three.js, Unreal Engine, and Cinema 4D for image-based lighting (IBL) and 360° equirectangular skyboxes, Radiance .hdr files encode floating-point light intensity using three 8-bit RGB mantissas and a shared 8-bit exponent.

Why Convert HDR to PNG?

Web browsers, document editors, and standard image viewers cannot read the #?RADIANCE header or decode linear RGBE floating-point luminance. Converting .hdr to PNG maps the linear radiance data into the sRGB color space (-colorspace sRGB) with automatic level normalization (-auto-level) and saves the result without JPEG block artifacts—ideal for creating high-precision background plates, thumbnails, or WebGL fallback textures.

How to Convert HDR to PNG

  1. Select your .hdr file from your device or paste a file URL.
  2. Click "Convert to PNG!" to decode RGBE luminance and export an sRGB PNG.
  3. Download the PNG image, or compress and resize it with our PNG optimizer and image resizer.
