Will Lightroom open ORF?

ORF is the RAW format used by every Olympus and OM SYSTEM camera since the E-1 in 2003, including the OM-1, OM-5, E-M1 Mark III, E-M5 Mark III, PEN-F, and the Tough TG-6. The format stores 12-bit or 14-bit sensor data from Micro Four Thirds chips alongside Olympus's in-camera Art Filter metadata. Travel photographers, macro enthusiasts using the 60mm f/2.8, and birders running the 300mm f/4 PRO convert ORF to JPG when sharing to Instagram, 500px, or stock libraries that reject RAW uploads.

Olympus Workspace (free, replaces the old Olympus Viewer 3) is the only software that fully applies the camera's Live Composite, ND filter simulation, and Pro Capture buffer logic when developing ORF. Lightroom and Capture One read ORF but ignore these computational results, which matters for OM-1 owners using the Handheld High-Res 50MP mode - that file is technically ORI, a variant. Convert via Workspace if you want the merged result; convert direct ORF for the single-frame 20MP base file.

Underwater shooters using the TG-6 in PT-059 housings rely on ORF to JPG conversion because dive log sites (DiveBoard, Scubapro Logbook) only accept JPG. The TG-6's RAW captures the magenta cast at depth that the JPG engine over-corrects, so processing ORF and re-exporting at quality 92 preserves accurate fish coloration. Wildlife shooters with the OM-1 II's 80fps Pro Capture often have 1000+ ORF files per session - batch conversion to JPG at 3000px makes culling on a laptop practical.

Reasons to convert ORF to JPG usually come down to compatibility, file-size, or specific feature requirements. Common situations:

• An app or platform only accepts JPG uploads.
• You need a feature unique to JPG (e.g. transparency, vector scaling, animation, multi-page pages, etc.) that ORF doesn't provide.
• You're optimising file size — modern formats often produce smaller files than the older format you started with.
• You need a single archival format across a project so files behave consistently in the same viewer.

1. Open the ORF → JPG tool on jpg.now.
2. Drag your ORF file onto the drop zone, or click Select files. You can drop a whole folder of files at once.
3. The output is fixed to JPG. If the format supports extra options (page size, transparency background, quality, EXIF stripping), tweak them in the right-hand panel.
4. Click Convert. The job runs on our server and finishes in a few seconds for typical photos.
5. Download the result. Files stay in storage for 24 hours and are then permanently deleted.

The entire flow is free for the first 10 jobs per day with no signup required. A free account doubles that quota; a premium plan removes the limit entirely.

• Use OM Workspace's Auto Tone for a starting point that matches the camera JPG engine - third-party converters apply a flatter base curve and require more manual lifting.
• For Pro Capture sequences, batch-rename ORFs by capture time before converting, otherwise the JPGs hit the Finder in alphabetical chaos that breaks burst review.
• If you shot Handheld High-Res, you want the ORI file (50MP merged), not the companion ORF (20MP base) - check the file extension before batch processing.
• Export at sRGB for web and social, AdobeRGB only if your gallery print lab specifically requests it - Instagram strips wide gamut and looks dull as a result.
• Strip the Olympus maker note via ExifTool before stock submissions - some agencies flag the proprietary tags as suspicious metadata and reject the upload.
