Convert Radiance HDR to JPG
A .hdr file stores real light intensities rather than screen brightness values — often thousands of times more range than a monitor can display. That is why opening one in ordinary software either fails or shows a washed-out, badly exposed image.

Why Convert HDR to JPG?
Radiance HDR is a 32-bit floating-point format built for lighting simulation and 3D rendering, where a light source might be a thousand times brighter than a wall. JPG holds 8 bits per channel, which covers what a screen can actually show. The conversion has to decide how to fit one into the other.
Radiance HDR files store light values far beyond what a screen can show, so converting always involves compressing that range down to displayable levels. MiConvert applies ImageMagick's tone mapping, which produces a reasonable neutral result — not the artistic grade you would get from hand-tuning exposure in a dedicated HDR editor.
For 3D artists the common use is turning an HDRI environment map into a preview or reference image. For photographers, .hdr usually comes out of a bracketing merge and JPG is simply the deliverable. Either way keep the .hdr — the range it holds cannot be recovered from the JPG.

Frequent Questions
How to convert HDR photo to normal?
That is what this conversion does: the high dynamic range is tone-mapped into the range a normal display can show, producing an ordinary viewable JPG. Upload the .hdr above and choose JPG.
Can JPG display HDR?
Not in the true sense. Standard JPG is 8-bit and carries no HDR metadata, so it shows a tone-mapped version rather than actual high dynamic range. Newer HDR-capable formats such as AVIF and JPEG XL can carry real HDR data; classic JPG cannot.
What is HDR JPEG?
It usually means a JPEG produced by merging bracketed exposures — a normal 8-bit file that merely looks like it has more range because it was tone-mapped from HDR sources. Some newer variants embed gain maps for true HDR display, but those are a different thing from a .hdr file.
How do I convert HEIC to JPG?
Different format, different page — but the same converter handles it. HEIC is Apple's photo format; .hdr is Radiance high dynamic range from rendering and 3D work.
Why does my converted image look flat or grey?
Tone mapping compresses a very wide range into a narrow one, which reduces contrast by definition. For a specific look, tone-map in Photoshop, Luminance HDR or your 3D application first, then convert the result.
What programs open .hdr files?
Photoshop, Affinity Photo, Blender, Luminance HDR, Krita and most 3D renderers. General-purpose image viewers and browsers generally do not.
