About HDR
Greg Ward made the RGBE format for Radiance, his lighting simulation software, in the late 1980s. It became the format of HDRIs, the panoramas of real light that 3D artists light scenes with, shared by sites like Poly Haven.
An HDR file keeps each pixel as red, green and blue with a shared exponent, four bytes that cover a huge range of light, packed with run lengths.
Filepeek reads it in your browser and tone maps it for your screen. Exposure brightens or darkens the light by up to 6 stops to see into the sun or the shade, and Export saves the picture as shown, as PNG or JPEG.

Questions
How do I open an .hdr file?
Drop it on this page or press Peek an HDR. It opens tone mapped for your screen, with nothing to install.
Can I see the sun's detail in an HDRI?
Yes. Open Exposure and drag it below 0 to darken the light by stops. Reset puts it back.
Can I convert HDR to JPEG?
Yes. Choose Export, then Save as JPEG. It saves the picture at the exposure on show.
Is my image uploaded?
No. The image opens inside your browser and never leaves your device.
