PSD to EXR Converter
Convert PSD to EXR in your browser. PSD files usually come from Photoshop and apps that save Photoshop documents, such as Affinity Photo, GIMP, Photopea and Krita; EXR is the better fit for visual effects, compositing and 3D render output. You get a ZIP-compressed OpenEXR with 16-bit half-float channels, the 8-bit sRGB values converted to linear light. Nothing is uploaded.

Why use Aback Images for psd to exr
Where the EXR goes next
EXR opens in Nuke, Blender, Houdini, After Effects, DaVinci Resolve, Photoshop, Krita and OpenImageIO.
EXR next to PSD
Both sides are lossless, so the size depends on how well the EXR encoder handles this picture compared with the PSD's raw or RLE (PackBits) channel data, ZIP in some 16 and 32-bit files.
Written without a lossy pass
The EXR is written losslessly, so the pixels decoded from the PSD 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.
PSD vs EXR
What changes from PSD to EXR
Encoding: the PSD uses raw or RLE (PackBits) channel data, ZIP in some 16 and 32-bit files; EXR uses none, RLE, ZIP, PIZ, PXR24, B44 or DWA, chosen per file, and the download is a ZIP-compressed OpenEXR with 16-bit half-float channels, the 8-bit sRGB values converted to linear light.
Bit depth: 8, 16 or 32 bits per channel in the PSD; EXR allows 16-bit half or 32-bit floating point per channel, and the EXR written here has 16-bit half float per channel. 16 and 32-bit documents are reduced to 8 bits per channel.
Colour: RGB, CMYK, Lab, greyscale, indexed or multichannel in the PSD; EXR supports scene-linear RGB, often ACEScg or linear Rec.709, written here as linear-light RGB.
Transparency: the PSD stores it as transparent layers plus extra alpha channels; the EXR keeps it as an A channel stored like any other channel.
Other images: the PSD can hold layers, masks, adjustment layers and smart objects; only the main image is converted.
Metadata: the PSD can carry XMP, EXIF, IPTC and ICC in image resource blocks; EXR can carry named header attributes such as chromaticities, timecode and camera data, but nothing is copied across.
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.
PSD files usually come from Photoshop and apps that save Photoshop documents, such as Affinity Photo, GIMP, Photopea and Krita.
About EXR
OpenEXR is the high dynamic range format of film visual effects. It stores half or full floating-point channels in linear light, plus any extra render passes, and is the working format of compositing pipelines.
An EXR starts with the magic number 76 2F 31 01 and a version field, then a header of named, typed attributes (channels, compression, dataWindow, displayWindow) and a table of offsets to scanline or tile blocks.
When converting PSD to EXR makes sense
EXR is the better choice for visual effects, compositing and 3D render output, while PSD suits editing in Photoshop.
EXR strengths: True high dynamic range in linear light; Any number of channels and render passes; Lossless compression options. Drawbacks to weigh: Needs tone mapping to look right on a normal screen; Very large files; No browser or phone support.
Limitations
- The merged composite is converted, so hidden layers stay hidden and visible ones are flattened together.
- Files saved with Maximize Compatibility turned off may hold no full-size composite; then only the small embedded thumbnail is available.
- No range is added: the EXR holds the 8-bit picture in linear light, and nothing in it is brighter than the original white.
- Compositing and 3D software read the EXR as linear light, the convention for the format, so it displays correctly there.
- The file holds colour and, when the image has transparency, an alpha channel; there are no extra render passes.

Frequently asked questions
Does converting PSD to EXR lose quality?
EXR is written losslessly, so the pixels are stored exactly as decoded. 16 and 32-bit documents are reduced to 8 bits per channel. Not carried over: any layers.
Is transparency kept in the EXR?
Yes. PSD stores it as transparent layers plus extra alpha channels, and the EXR is written with an alpha channel, so transparent areas stay transparent.
Are PSD layers kept?
No. The flattened composite that Photoshop saves inside the file is converted, so the result looks like the PSD with all visible layers merged. Files saved without Maximize Compatibility fall back to the embedded thumbnail.
Does saving as EXR add dynamic range?
No. The values come from an 8-bit image, converted to linear light so compositing software displays them correctly, but nothing brighter than the original white is invented. The file is ready to use as a plate or texture in an EXR pipeline.
Which apps open EXR files?
Nuke, Blender, Houdini, After Effects, DaVinci Resolve, Photoshop, Krita and OpenImageIO. 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.
