Why convert PSD to HDR?
- High dynamic range in a compact encoding
- Standard for environment maps
- Simple format
- Works with: Blender, Photoshop, Unity, Unreal and Radiance tools
What to expect from this conversion
- Both formats store the pixels without loss, so the picture stays identical. Only the file size and compatibility change.
- HDR has no transparency, so transparent areas are filled with a background colour. White by default, and you can choose another colour in the options.
- HDR stores light in linear floating-point values, so your pixels are converted from sRGB to linear. The result looks the same in an HDR-aware viewer but does not gain real dynamic range.
- The flattened composite of your PSD is converted. Individual layers, masks and adjustment layers are not exported.
- Browsers do not display HDR files, so use it in editors, print workflows or development tools rather than on a web page.

- Check that HDR is selected as the target and adjust the options if you want.
- Press Convert, then download your new HDR file when it finishes.
Tips for the best result
- Use quality 80 to 90 for photos: it is visually close to the original at a much smaller size.
- Set a width if the image will be shown on a small screen, which also reduces the file size.
- Choose a background colour before converting transparent images to a format without transparency.
