ORF to PSD Converter
Convert ORF to PSD in your browser. The preview inside the maker notes is found by scanning the whole file, and that preview is what gets converted. No raw development happens here. You get an 8-bit RGB Photoshop document with one layer and a merged composite, RLE compressed, with transparency kept. Nothing is uploaded.

Why use Aback Images for orf to psd
Where the PSD goes next
PSD opens in Photoshop, Affinity Photo, GIMP, Photopea and Krita.
PSD next to ORF
The PSD holds the camera preview's pixels with lossless compression: usually smaller than a 12 to 30 MB raw file, though far larger than a JPEG of the same photo.
No new artefacts
The preview inside the ORF is a camera JPEG; the PSD stores its decoded pixels losslessly, so this step adds no compression damage of its own.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
ORF vs PSD
What changes from ORF to PSD
Encoding: the ORF uses losslessly compressed sensor data, with a preview and thumbnail; 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: 12 bits per channel in the ORF; PSD allows 8, 16 or 32 bits per channel, and the PSD written here has 8 bits per channel. The sensor's 12 bits are not used: the 8-bit camera preview is converted.
Colour: camera RGB from a Bayer mosaic in the ORF; PSD supports RGB, CMYK, Lab, greyscale, indexed or multichannel, written here as 8-bit sRGB.
Metadata: the ORF can carry EXIF and Olympus maker notes, which also contain the preview; PSD can carry XMP, EXIF, IPTC and ICC in image resource blocks, but nothing is copied across.
About ORF
ORF is the raw format of Olympus and OM System cameras, built around Four Thirds and Micro Four Thirds sensors. It stores 12-bit sensor data with a JPEG preview kept inside Olympus's maker notes.
ORF looks like TIFF but replaces the version number 42 with the letters 'RO', so a little-endian file starts 'IIRO' and generic TIFF readers reject it. Its JPEG preview is not in the main image directory but inside the camera-settings block of Olympus's maker notes.
ORF files usually come from Olympus E-series DSLRs, OM-D and PEN mirrorless cameras and OM System bodies.
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 ORF to PSD makes sense
PSD is the better choice for editing in Photoshop, while ORF suits editing Olympus and OM System photos in a raw developer.
PSD strengths: Keeps every layer and edit. Drawbacks to weigh: Huge files; Cannot be viewed on the web or most phones.
Limitations
- High Res Shot files combine several exposures in camera; the preview shows the combined result at its stored size.
- 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 ORF to PSD lose quality?
PSD is written losslessly, so the pixels are stored exactly as decoded. Those pixels come from the camera's JPEG preview, so its compression stays, but nothing new is lost. The sensor's 12 bits are not used: the 8-bit camera preview is converted.
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.
