Drop one or more .orf files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
ORF to JPG

Developing a .orf camera file into .jpg turns unprocessed sensor data into a finished image any app can open. An .orf file is an Olympus RAW Format photograph from Olympus and successor OM System cameras, storing the Four Thirds sensor's output before in-camera processing. The extension has covered every Olympus digital generation from early E-system DSLRs through today's OM-1 mirrorless bodies.
A .jpg file is a photograph or other continuous-tone image compressed with the JPEG standard, the most widely used image codec ever shipped. Nearly every camera, phone, and website produces or accepts .jpg files, which makes it the default interchange format for photos. For this route the practical draw is opens everywhere, from 1990s software to the newest phone and excellent size-to-quality ratio for photographic content — balanced against every re-save re-compresses the image, so quality erodes across editing generations, which is worth knowing before you commit a large batch.
Why convert ORF to JPG?
The practical trigger for this conversion is usually a mismatch: with .orf, the nonstandard TIFF header confuses generic tools that assume spec compliance. Switching to .jpg buys you opens everywhere, from 1990s software to the newest phone, which is why it is the better fit for publishing photographs on websites where file size and universal support matter. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
ORF vs JPG at a glance
| Aspect | Olympus RAW (.orf) | JPEG image (.jpg) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Lossy — discards detail it judges invisible to shrink files |
| How it stores data | tIFF-like structure with deliberate header deviations (magic bytes IIRO/IIRS rather than standard TIFF) that trip naive parsers | compresses 8x8 pixel blocks with a discrete cosine transform followed by quantization, which is where detail is discarded |
| Strongest at | developing photos from Olympus and OM System Micro Four Thirds cameras | publishing photographs on websites where file size and universal support matter |
| Weak spot | the nonstandard TIFF header confuses generic tools that assume spec compliance | every re-save re-compresses the image, so quality erodes across editing generations |
| Metadata | eXIF is complete and Olympus MakerNotes are unusually detailed about stabilization, focus bracketing, and computational modes; XMP normally lives in sidecars | carries EXIF (camera settings, GPS, orientation), XMP, and IPTC records in APPn marker segments, plus embedded ICC color profiles and thumbnails |
Pick JPG as the output
Select .jpg in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if JPG is selectable, the route is real and validated.
Convert on your device
Press Convert. A LibRaw WebAssembly decoder demosaics the sensor data in your browser and renders a developed image ready for export.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid JPG file. Outputs keep the original filename with the .jpg extension.
ORF to JPG questions, answered
Will converting ORF to JPG lose quality?
Some. Since orf is lossless-oriented and jpg is lossy-oriented, the encoder will discard detail it judges least visible; the quality slider controls how aggressive that is. Keep the original .orf if you may need a pristine master later.
Is it private to convert ORF files here?
Yes — the .orf file is processed inside your browser tab and never uploaded. A LibRaw WebAssembly decoder demosaics the sensor data in your browser and renders a developed image ready for export. Close the tab and the file is gone from memory.
Where will the JPG file work?
JPEG is supported by every mainstream operating system, browser, image editor, and printer driver in use today. It decodes natively on iOS, Android, Windows, macOS, and Linux without any add-on codecs, and every browser has rendered it since the format reached the web in the 1990s.
Will the JPG file be bigger or smaller than my ORF?
Smaller, usually dramatically so — that is the main reason this route exists. The quality slider trades size against fidelity; the default sits at the point where most people cannot spot the difference.
What happens to the metadata in my ORF file?
In .orf, eXIF is complete and Olympus MakerNotes are unusually detailed about stabilization, focus bracketing, and computational modes; XMP normally lives in sidecars. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
