HDR to PSD Converter
Convert HDR to PSD in your browser. HDR files usually come from HDRI environment maps, 360° panoramas and lighting simulation; PSD is the better fit for editing in Photoshop. You get an 8-bit RGB Photoshop document with one layer and a merged composite, RLE compressed, with transparency kept. Nothing is uploaded.

Download the .psd files one at a time or together as a ZIP.
Why use Aback Images for hdr to psd
Where the PSD goes next
PSD opens in Photoshop, Affinity Photo, GIMP, Photopea and Krita.
PSD next to HDR
Both sides are lossless, so the size depends on how well the PSD encoder handles this picture compared with the HDR's run-length encoded RGBE scanlines.
Written without a lossy pass
The PSD is written losslessly, so the pixels decoded from the HDR arrive unchanged, apart from precision beyond 8 bits per channel.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
HDR vs PSD
What changes from HDR to PSD
Encoding: the HDR uses run-length encoded RGBE scanlines; PSD uses raw or RLE (PackBits) channel data, ZIP in some 16 and 32-bit files, and the download is an 8-bit RGB Photoshop document with one layer and a merged composite, RLE compressed, with transparency kept.
Bit depth: an 8-bit mantissa per channel sharing an 8-bit exponent (RGBE), 32 bits per pixel in the HDR; PSD allows 8, 16 or 32 bits per channel, and the PSD written here has 8 bits per channel. The high dynamic range is mapped to 8 bits per channel, and values above white clip.
Colour: linear RGB (or XYZ in the XYZE variant) in the HDR; PSD supports RGB, CMYK, Lab, greyscale, indexed or multichannel, written here as 8-bit sRGB.
Metadata: the HDR can carry a text header with FORMAT, EXPOSURE and optional comments; PSD can carry XMP, EXIF, IPTC and ICC in image resource blocks, but nothing is copied across.
About HDR
Radiance .hdr stores high dynamic range light values, widely used for 3D environment maps and HDRI lighting.
A Radiance file starts with '#?RADIANCE' (or '#?RGBE'), text lines such as FORMAT=32-bit_rle_rgbe and EXPOSURE, a blank line, a resolution line like '-Y 2048 +X 4096', then the scanlines.
HDR files usually come from HDRI environment maps, 360° panoramas and lighting simulation.
About PSD
PSD is Adobe Photoshop's layered working format. It keeps layers, masks and effects, but almost nothing outside Photoshop can display it, so finished designs are exported to PNG or JPG.
A PSD has five sections: a header ('8BPS', channel count, size, depth, colour mode), colour mode data, image resources (thumbnail, ICC, XMP, resolution), layer and mask information, and finally the merged composite image that the Maximize Compatibility option saves.
When converting HDR to PSD makes sense
PSD is the better choice for editing in Photoshop, while HDR suits 3D lighting and environment maps.
PSD strengths: Keeps every layer and edit. Drawbacks to weigh: Huge files; Cannot be viewed on the web or most phones.
Limitations
- Light values above 1.0 are clipped rather than tone-mapped, so the sun and bright sky turn flat white.
- Environment maps are 2:1 equirectangular panoramas, so the picture looks stretched near the top and bottom, as it should.
- Files in the XYZE variant cannot be read here; RGBE files, the common kind, can.
- The Photoshop document holds the picture as a single layer: a starting point for editing, not a reconstruction of layers.
- Photoshop, Affinity Photo, GIMP and Photopea open it.

Frequently asked questions
Does converting HDR to PSD lose quality?
PSD is written losslessly, so the pixels are stored exactly as decoded. The high dynamic range is mapped to 8 bits per channel, and values above white clip.
Which apps open PSD files?
Photoshop, Affinity Photo, GIMP, Photopea and Krita. It does not open in web browsers.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
