SVG to ORF Converter
Convert SVG to ORF in your browser. You download a Linear DNG (.dng), not a .orf: only an Olympus camera can create a genuine ORF, and every editor that opens ORF also opens DNG. Nothing is uploaded.

How to use SVG to ORF
- 1
Add your SVG files: drop them here, choose them, or paste from the clipboard.
- 2
Pick the colour that replaces transparent areas, since DNG has none.
- 3
Click Convert. Each file is decoded and encoded in a background thread on this device.
- 4
Download the .dng files one at a time or together as a ZIP.
Why use Aback Images for svg to orf
Where a ORF would go
ORF files are opened by OM Workspace, Lightroom, Photoshop Camera Raw, Capture One and RawTherapee, and every one of them opens the DNG too.
DNG next to SVG
Rasterising turns a description of shapes into stored pixels, so the DNG is usually larger than a small SVG, and grows with the size you render at.
Written without a lossy pass
The DNG is written uncompressed, so the pixels decoded from the SVG arrive unchanged.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
SVG vs ORF
What changes from SVG to ORF
Encoding: the SVG uses XML text describing paths, shapes and text, sometimes gzipped as .svgz; ORF uses losslessly compressed sensor data, with a preview and thumbnail, and the download is a Linear DNG: demosaiced 8-bit RGB with the colour matrices raw editors need.
Bit depth: not fixed: coordinates and colours are continuous values in the SVG; ORF allows 12 bits per channel, and the DNG written here has 8 bits per channel, linearised.
Colour: sRGB by default, other spaces through CSS colour functions in the SVG; ORF supports camera RGB from a Bayer mosaic, written here as 8-bit sRGB.
Transparency: the SVG stores it as opacity on any element, with anti-aliased edges; the DNG has none, so transparent areas are filled with the colour you choose.
Animation: SMIL or CSS animation described in the markup; a single still rendering is converted.
Metadata: the SVG can carry title, description and RDF metadata elements; ORF can carry EXIF and Olympus maker notes, which also contain the preview, but nothing is copied across.
About SVG
SVG describes shapes, paths and text as XML instead of pixels, so it stays crisp at any size. It is the standard for logos, icons and illustrations on the web.
An SVG is an XML document: a root <svg> element with a viewBox, then paths, shapes, text, gradients and filters. It can also embed raster images and, dangerously, scripts, which is why untrusted SVG is sanitized before rendering here.
SVG files usually come from icon sets, logos, design tools (Figma, Illustrator, Inkscape) and diagram exports.
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 come from Olympus E-series DSLRs, OM-D and PEN mirrorless cameras and OM System bodies.
When converting SVG to ORF makes sense
Forms and workflows that ask for ORF usually feed a raw editor, and each of those opens DNG as well, so the DNG can take the ORF's place. Keep the SVG if you only need to view or share the picture.
What ORF offers when it comes straight from the camera: Compact files from a smaller Four Thirds sensor; High Res Shot results stored as a single file; Supported across two decades of Olympus and OM System bodies. Its drawbacks: An 'IIRO' header that generic TIFF readers reject; 12-bit depth, less than most full-frame raw files; A preview hidden inside the maker notes.
Limitations
- Rasterising fixes the picture at one pixel size; set a larger size under More options if you need to print or zoom.
- Text that was not converted to outlines is drawn with the fonts on this device, so lettering can look different from the designer's screen.
- The DNG holds the decoded 8-bit pixels, so it adds no dynamic range or detail beyond the SVG.

Frequently asked questions
Why do I get a .dng file instead of a .orf?
A real ORF is written by Olympus cameras and holds the sensor's own readings (12 bits per channel, stored as losslessly compressed sensor data, with a preview and thumbnail) along with EXIF and Olympus maker notes, which also contain the preview. An SVG holds no sensor data, so no software outside the camera can create a genuine ORF. The Linear DNG you get instead is Adobe's open raw format, and every editor that opens ORF files opens it with the same raw controls. It holds decoded pixels, so it adds no quality or dynamic range.
Does converting SVG to ORF lose quality?
DNG is written uncompressed, so the pixels are stored exactly as decoded.
What happens to transparency when converting SVG to ORF?
SVG stores transparency as opacity on any element, with anti-aliased edges. DNG has no alpha channel, so transparent pixels are composited onto a solid colour, white unless you pick another. To keep transparency, convert to PNG, WebP or AVIF instead.
What resolution will the output be?
SVG has no fixed pixel size, so it is rendered at its declared width and height. Use the resize options to render it larger: because it is vector, an SVG stays perfectly sharp at any size you choose here. Files are sanitized first, so scripts and external references never run.
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.
