What is HDRView?
HDRView helps you examine high-dynamic-range images rather than just browse them. It is aimed at research and rendering workflows where you need to compare an image with a reference, inspect individual channels, or understand why colors and brightness look different. Pixel readouts, histograms, metadata panels and color-space controls put the underlying image data alongside the preview.
You can adjust exposure and gamma, use false-color views, and compare files or channel groups with difference and other blend modes. Multi-layer and multi-part OpenEXR support makes it useful for inspecting render outputs. Basic editing includes cropping, resizing, color adjustments and filters, with an undo history. Windows HDR output uses Advanced Color on a compatible HDR display; an ordinary SDR screenshot cannot demonstrate that output range.
This entry links to the publisher's HDRView 3.1.0 Windows x64 ZIP, released on October 26, 2026. Keep HDRView.exe and its assets folder together after extraction. A separate ARM64 package is available from the publisher. The Softonic discovery page still lists 3.0.2, so its version and package size should not be treated as details of this download.
Format support depends on what was compiled into the build; the publisher points to About → Build info for the actual list. In version 3.1.0, HEIF/AVIF gain maps cannot be exported. The screenshot is the publisher's cross-platform desktop interface illustration, not a capture of a locally installed Windows copy.
What it offers
- Inspect pixel values, histograms, image metadata and color-space information.
- Compare a current image with a reference using difference, subtract and other blend modes.
- Browse channels and layers in OpenEXR files, including multi-part images.
- Adjust exposure, gamma and false-color views; crop, resize and apply basic filters with undo history.
- Use Windows Advanced Color for HDR output on a compatible HDR display.
Good to know
- Version 3.1.0 cannot export HEIF/AVIF gain maps.
- Available file formats depend on build options; check About → Build info rather than assuming every documented decoder is included.
- Keep the executable and its assets folder together; the selected ZIP is the x64 package, not the separate ARM64 build.
