When to Convert PSD to HDR
HDRI Environment Maps
3D artists convert psd to hdr to create HDR environment maps for image-based lighting (IBL) in Blender, Cinema 4D, and Substance Painter workflows.
PBR & Lighting Workflows
Physically-based rendering pipelines require HDR light probes and sky textures. Use our psd to hdr converter to prepare psd to hdr image files as HDR inputs for renderers like Arnold, V-Ray, and Cycles.
Real-time 3D & Game Engines
Unreal Engine, Unity, and Godot all accept HDR files for skyboxes, reflection captures, and sky atmosphere systems. Convert psd to hdr file format to feed these pipelines directly.
Web 3D & WebGL
Three.js, Babylon.js, and PlayCanvas use HDR environment maps for realistic reflections and ambient lighting. Our psd to hdr online produces HDR files compatible with all major WebGL libraries.
Photography & Tone Mapping
Photographers convert psd to hdr to HDR for tone-mapping experiments in tools like Luminance HDR, Photomatix, and Darktable's HDR merge workflow.
Machine Learning & CV Datasets
Computer vision pipelines and neural rendering research often require HDR inputs. Convert psd to hdr to build HDR dataset batches entirely in the browser - no server infrastructure needed.
Understanding How to Convert PSD to HDR
What is PSD to HDR Conversion?
When you convert psd to hdr, you transform a layered image format (Adobe Photoshop) PSD image into the Radiance HDR format - the most universally supported High Dynamic Range image format in 3D graphics, VFX, and real-time rendering. Unlike PSD, which stores each colour channel as an 8-bit integer clamped to 0-255, a psd to hdr file encodes pixel values using the RGBE (Red-Green-Blue-Exponent) scheme: three mantissa bytes plus a shared binary exponent, enabling a representable range of approximately 10−38 to 1038. This makes the psd to hdr file the standard container for HDRI environment maps, light probes, and sky textures in every major 3D engine and renderer.
How Our PSD to HDR converter Works
- Load - your PSD image is decoded in the browser using the HTML5 Canvas API. No file is ever uploaded; all processing runs locally on your device.
- Encode - each RGB pixel is converted from 8-bit integer values to a 4-byte RGBE quad using a shared binary exponent, then written into a spec-compliant Radiance HDR binary file with the required ASCII header, format declaration, exposure metadata, and size line.
- Download - the finished psd to hdr file is packaged as a binary Blob and offered for immediate download. Multiple files are bundled into a ZIP archive automatically.
Output PSD to HDR file Structure
- Radiance RGBE format: fully compatible with Blender, Photoshop, Lightroom, GIMP, Three.js, Babylon.js, Unreal Engine, Unity, and all OpenEXR/Radiance-aware tools that accept HDR environment maps.
- Uncompressed RGBE scanlines: the psd to hdr file uses the original uncompressed (non-RLE) scanline layout for maximum compatibility with all HDR loaders, including web-based RGBE decoders.
- EXPOSURE=1.0 metadata: a standard exposure value of 1.0 is written into the header so psd to hdr output integrates cleanly with tone-mapping and rendering pipelines without unexpected brightness scaling.
- Top-down orientation: scanlines are written top-to-bottom ("-Y height +X width"), matching the most common orientation expected by 3D engines and HDR image editors.
Privacy, Security & Availability
Our psd to hdr online runs 100% in your browser - no psd to hdr image files are ever uploaded to a server. Conversion is instant because all processing happens locally on your device. The tool is completely free, requires no signup or account, imposes no file size limits, and works on any modern desktop or mobile browser without additional plugins or software.

Frequently Asked Questions About PSD to HDR converter
A psd to hdr converter is a browser-based tool that transforms PSD images into the Radiance HDR format. When you convert psd to hdr, each pixel is re-encoded using the RGBE (Red-Green-Blue-Exponent) scheme, producing an HDR file compatible with Blender, Photoshop, Three.js, Unreal Engine, Unity, and virtually all 3D and VFX tools that use HDR environment maps.
You should convert psd to hdr image to HDR when your 3D engine, renderer, or compositing tool specifically requires an HDR environment map or sky texture. HDR files store luminance using a shared exponent that far exceeds the 0-255 range of PSD, giving renderers the dynamic range they need for physically accurate image-based lighting and reflections.
Yes, completely. Our psd to hdr online runs entirely in your browser using the HTML5 Canvas API. Your psd to hdr image files are never uploaded to any server and never leave your device. All psd to hdr processing happens locally, so your files stay completely private.
After you convert psd to hdr, the resulting HDR file can be opened with Blender, Adobe Photoshop, Lightroom, GIMP, Darktable, Luminance HDR, HDRShop, Three.js, Babylon.js, Unreal Engine, Unity, Cinema 4D, and any application that supports the Radiance RGBE format. HDR is the most widely supported HDR interchange format in 3D graphics.
The psd to hdr converter re-encodes 8-bit SDR pixel values into the RGBE format using accurate shared-exponent math. The file is a valid, spec-compliant Radiance HDR container. However, the dynamic range of the output is limited by the source PSD image - a standard PSD captures SDR content only. True HDR content requires a multi-exposure merge or a capture device with HDR output.
Our psd to hdr converter has no artificial file size cap. Since conversion runs entirely in your browser, practical limits depend on your device's available memory. Most modern devices comfortably handle PSD images up to tens of megapixels when converting psd to hdr.
Yes. Drop or select multiple PSD files at once and convert them all in a single click. When you convert psd to hdr in batch mode, all output psd to hdr file files are automatically packaged into a ZIP archive and downloaded in one action.
