How to Convert PSD to HDR

Export PSD files for lighting and rendering tools, no Photoshop required

Why Convert PSD to HDR?

Like EXR, Radiance HDR (.hdr) is a target format that can actually benefit from PSD's optional 32-bit floating point mode, which Photoshop supports for genuine high dynamic range editing. Created in 1991, .hdr remains in use today by architectural lighting tools and some 3D rendering software, and converting a true HDR-mode PSD to it can carry forward real extended dynamic range rather than just changing the file container.

For a standard 8-bit PSD design, however, converting to HDR doesn't add brightness range that wasn't in the original — it simply produces a file format that specific lighting, rendering, or visualization software expects as input.

How to Convert PSD to HDR
  1. Install Turbo Batch Image Converter Pro on your Windows PC. Photoshop is not required.
  2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single PSD.
  3. Drag your PSD file or folder into the app window, enabling recursive folder scanning if needed.
  4. Set the "From" format to PSD and the "To" format to HDR.
  5. Click Convert. HDR files are written to the output folder, fully offline.
What Makes This PSD to HDR Converter Useful

  • Produces .hdr files compatible with architectural lighting and rendering tools
  • Bulk-convert entire project folders in a single batch job
  • Multi-core processing for fast handling of large batches
  • Runs fully offline, keeping unreleased work private
Frequently Asked Questions

Does converting PSD to HDR add dynamic range?

Only if your source PSD was created in Photoshop's 32-bit floating point mode; otherwise, a standard 8-bit PSD won't gain dynamic range simply by converting to HDR.

What's the difference between HDR and EXR as target formats?

EXR supports multiple layers, more channels, and higher precision, while HDR (Radiance RGBE) is a simpler, single-layer format still common in architectural lighting tools.

What software uses the .hdr format?

Photoshop, GIMP, Blender, and most major 3D renderers support .hdr, along with architectural lighting simulation tools that have long relied on the Radiance format specifically.
