ORF to JPG converter
Convert Olympus / OM System ORF files to JPG at full resolution, on your own device.
ORF is written by Olympus and OM System Micro Four Thirds bodies. Files are smaller than full-frame RAWs simply because the sensor is smaller.
Nothing here is uploaded. ORF files routinely run from 20 to 80 MB, which is exactly the size that upload-based converters reject or throttle. Invo reads the file straight from your disk in the browser, so size is not a constraint.
How it works
Your Olympus / OM System camera writes a full JPEG preview inside every ORF file — that is what the rear screen shows you. Invo locates it in the file's directory structure and extracts it directly, usually at full sensor resolution and in under a millisecond.
At 100% quality those original bytes are handed straight to you, so there is no re-encoding and no quality loss whatsoever. If the file has no usable preview, Invo falls back to a full LibRaw decode with your camera's recorded white balance.
When to convert, and when not to
Convert to JPG for sharing, uploading, printing through a lab, or sending client selections. Keep the ORF as your negative — it holds the highlight and shadow latitude that makes serious editing possible, and a JPEG has already discarded it.
Need a smaller file afterwards? Compress it or resize it.
Questions
Can I open ORF files without Photoshop or Lightroom?
Yes. This page converts ORF to JPG in your browser with nothing to install.
Is there a size limit for ORF files?
No. Files are read locally rather than uploaded, so even a 100 MB file is fine.
Will the JPG be full resolution?
In almost all cases. Olympus / OM System embeds a full-resolution preview in ORF files. Where a camera embeds only a small preview, Invo performs a complete decode instead.
Does converting lose quality?
At 100% quality the camera's own JPEG is copied byte for byte, so no. Lower settings re-encode and trade some quality for size.
Are my ORF files uploaded?
No. Everything happens in your browser.
