Edit ORF Files Online
Open Olympus RAW Format (ORF) files from Olympus / OM System cameras right in your browser — decode, color grade and export JPEG in minutes. Free, no upload, no software to install.
What is a ORF file?
ORF is the RAW format produced by OM System OM-1, OM-5, Olympus E-M1 Mark III, E-M10 IV, PEN E-P7 and other Micro Four Thirds cameras. ORF files carry the full 12-bit sensor data from Micro Four Thirds cameras — editing RAW recovers noticeably more shadow detail than the in-camera JPEG.
Because ORFis a RAW format, most image viewers and web tools can't open it. OpticRaw decodes it with LibRaw — the same engine used by professional desktop software — compiled to WebAssembly so it runs locally in your browser.
How to edit a ORF file online
- Open OpticRaw and drag your ORF file into the window.
- Wait a few seconds while the RAW is decoded (your camera's white balance is applied as the starting point).
- Edit with Lightroom-style tools: exposure, tone curve, HSL color mixer, color grading wheels, masking brush, crop & straighten.
- Click Export to save a full-resolution JPEG or PNG.
Why edit ORF instead of JPEG?
RAW keeps the full sensor data: highlights you can pull back, shadows you can lift cleanly, and white balance you can change after the fact. Editing the ORF file gives dramatically better results than editing the camera JPEG — especially for exposure mistakes and tricky light.
Just need a JPEG? You can also convert ORF to JPG in one click — full resolution, many files at once.

Frequently asked questions
Can I open ORF files online for free?
Yes. OpticRaw decodes ORF files directly in your browser using LibRaw (WebAssembly) — free, no watermark, no account.
Is my ORF file uploaded to a server?
No. The file is decoded and edited entirely on your device. It never leaves your computer.
How do I convert ORF to JPEG?
Open the ORF file, make any adjustments you want (or none), then click Export and choose JPEG. You get a full-resolution JPEG in seconds.
Do I need Lightroom or Photoshop to edit ORF?
No. This editor gives you Lightroom-style tools — tone curve, HSL mixer, color grading wheels, masking, crop — right in the browser.
Does editing change my original ORF file?
Never. Editing is non-destructive: the original RAW file stays untouched and you export a separate JPEG or PNG.
