ORF to EPS Converter
Convert ORF to EPS 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 EPS that wraps the pixels as a PostScript image; it contains no vector paths. Nothing is uploaded.

Why use Aback Images for orf to eps
Where the EPS goes next
EPS opens in Illustrator, CorelDRAW, InDesign, Affinity Designer, Ghostscript, and Inkscape through Ghostscript.
EPS next to ORF
The EPS stores the camera preview's pixels uncompressed, so it can be as large as the 12 to 30 MB raw file, or larger, depending on the preview's resolution.
No new artefacts
The preview inside the ORF is a camera JPEG; the EPS stores its decoded pixels uncompressed, 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 EPS
What changes from ORF to EPS
Encoding: the ORF uses losslessly compressed sensor data, with a preview and thumbnail; EPS uses PostScript program text, with an optional binary TIFF preview or an EPSI hex preview, and the download is an EPS that wraps the pixels as a PostScript image; it contains no vector paths.
Bit depth: 12 bits per channel in the ORF; EPS allows resolution-independent artwork, with previews usually 8-bit, and the EPS 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; EPS supports CMYK, RGB and spot colours, written here as 8-bit sRGB.
Metadata: the ORF can carry EXIF and Olympus maker notes, which also contain the preview; EPS can carry DSC comments such as %%BoundingBox, %%Creator and %%Title, 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 EPS
EPS is a PostScript drawing packaged for placing inside other documents. It was the exchange format of print and logo design for decades; most EPS files also carry a raster preview so layout software can show them.
An EPS is a PostScript program with DSC comments ('%!PS-Adobe-3.0 EPSF-3.0', %%BoundingBox). Files from Illustrator, Photoshop and CorelDRAW usually start with a 30-byte binary header (C5 D0 D3 C6) that points to a TIFF preview; others carry an EPSI hex preview between %%BeginPreview and %%EndPreview.
When converting ORF to EPS makes sense
EPS is the better choice for print artwork and logos for professional layout software, while ORF suits editing Olympus and OM System photos in a raw developer.
EPS strengths: Vector artwork that prints at any size; Accepted by print shops and older layout software; CMYK and spot colours. Drawbacks to weigh: Browsers and phones cannot display it; Needs a PostScript interpreter to render the vector data; Superseded by PDF and SVG.
Limitations
- High Res Shot files combine several exposures in camera; the preview shows the combined result at its stored size.
- The EPS holds pixels inside a PostScript wrapper, so it prints at the resolution of your image and will not get sharper when enlarged.
- Transparency is flattened onto the background colour, because the EPS image has no alpha channel.

Frequently asked questions
Does converting ORF to EPS lose quality?
EPS is written uncompressed, 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.
Is the EPS a vector file?
No. The EPS wraps the pixels as a PostScript image, which is what layout and print software need to place it, but it has no vector paths, so it does not get sharper when enlarged. For real vectors, trace the image to SVG first.
Which apps open EPS files?
Illustrator, CorelDRAW, InDesign, Affinity Designer, Ghostscript, and Inkscape through Ghostscript. 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.
