Convert Olympus ORF, Fuji RAF, and Sony ARW to JPG on Windows 10/11 with Batch Picture Resizer. Offline batch export, quality control, and mixed-camera folders—free download.

Olympus ORF, Fuji RAF, and Sony ARW files hold full sensor data, but Windows and most apps expect JPG. This guide shows how to convert ORF to JPG on a PC, along with RAF and ARW, using a desktop batch tool so nothing leaves your machine.

Download and install Batch Picture Resizer
Add ORF, RAF, or ARW files from a folder
Set JPEG as the output format and quality
Run the batch and check the output folder

Batch Picture Resizer reads ORF, RAF, and ARW in one queue on Windows 10 and 11. We often get folders mixed with ORF from an OM System body, RAF from a Fuji X series, and ARW from a Sony Alpha shoot. Windows Photos may show a thumbnail for one brand and a blank icon for another until a codec or converter is installed. A single desktop ORF to JPG converter that also reads RAF and ARW saves reinstalling tools per camera.

Batch Picture Resizer: offline batch ORF, RAF, and ARW to JPG on Windows 10/11.
Adobe DNG Converter: free intermediate step if you need DNG before JPEG in another editor.
XnConvert / Converseen: solid free batch options when you only need format change.
Frequently Asked Questions

ORF, RAF, and ARW: What Each Format Is

|--------|----------------|-----------|----------------------|

| ORF | Olympus / OM System | .orf | TIFF/EP-based RAW; needs a decoder Windows does not ship |
| RAF | Fujifilm X / GFX | .raf | Proprietary container; large files, strong color science in RAW |
| ARW | Sony Alpha / RX | .arw | Often lossy-compressed RAW; check quality slider on export |

All three are camera RAW containers, not finished JPEGs. Converting ORF to JPG (or RAF / ARW) means demosaicing and encoding on your PC. For a wider list of brands, see our RAW to JPG converter guide; for Adobe DNG workflows, see DNG to JPG on Windows.

How to Convert ORF, RAF, and ARW to JPG in Batch Picture Resizer

Download Batch Picture Resizer from the button above and run the installer. The setup is under 11 MB and does not require a subscription.

Install Batch Picture Resizer on Windows.

Launch the program. The file list starts empty.

Select JPEG output for ORF RAF ARW conversion.

Optional: open the Resize tab to cap long edge (for example 2048 px) before you convert ORF to JPG for web galleries.

JPEG Quality and EXIF for ORF, RAF, and ARW

JPEG is lossy. Pick the quality once per batch instead of re-saving the same exports.

Quality slider

90-95 keeps skin tones and foliage clean for ORF and RAF files. ARW exports at the same settings are usually slightly smaller because of Sony compression in some bodies.

Color and EXIF

Leave EXIF transfer enabled if you need capture date and lens data in the JPEG. If you deliver to a client who strips metadata, turn it off in the same run.

Folder layout

Mirror the source tree when you convert a whole card backup. That keeps ORF, RAF, and ARW files from different shoots separated in the output.

When to Use Another Tool

Adobe DNG Converter is useful if your editor only accepts DNG. Free batch tools such as XnConvert handle ORF to JPG when you already use them for other formats. For Canon-heavy shoots, see the CR2 to JPG converter page; for Nikon NEF from the same archive, see our NEF to JPG converter. Batch Picture Resizer stays on one queue when the folder mixes Olympus, Fuji, and Sony files.
