ORF to JPEG 2000 Converter

Convert ORF files to JPEG 2000. Batch, free and without uploading.

This tool converts ORF files to JPEG 2000. ORF is the RAW format of Olympus cameras. It keeps unprocessed sensor data; conversion uses the camera’s white balance and colour settings.

JPEG 2000 is used in archives, digital cinema and medical imaging. JPEG 2000 is lossy, and you choose the quality with the slider. For photos, 80–90% makes the file much smaller with a loss you won’t notice. RAW files are large, so each photo may take a few seconds.

Conversion happens inside your browser; your files are never sent to a server.

How to use

1. Drag and drop your ORF files, paste them from the clipboard, fetch one from a link, or use "Choose files".
2. Set the quality and, if you like, a maximum size.
3. Press "Convert" and download the JPEG 2000 files one by one or as a ZIP.

Frequently asked questions

Will converting to JPEG 2000 reduce quality?

JPEG 2000 is lossy, but at 85–90% quality the difference isn’t visible. Lower quality means a smaller file.

How many files can I convert at once?

There is no limit. Select hundreds of files together and download the results as one ZIP.

Are my files uploaded anywhere?

No. Your ORF files are converted to JPEG 2000 inside your browser and never sent to a server.
