Convert ORF to TIFF — Lossless Archive
ORF is Olympus's proprietary RAW format. TIFF is the format archives and print workflows actually expect: lossless, colour-managed, and readable by essentially every professional imaging tool without vendor software.

Apple's format. Excellent quality at small sizes.
Lossless format. Large files, ideal for print/archival.
256 colors max. Best for simple graphics.
Uncompressed bitmap. Very large files.
Vector trace. Best for logos and simple graphics. Not a pixel-perfect conversion.
Same format? You might want to compress instead.

Lossless format — files can be large
GIF is limited to 256 colors
Best for logos, icons, and line art. Photos produce stylized results.
BMP files are uncompressed and can be very large. Consider TIFF (LZW) or PNG for lossless with smaller file sizes.
Leave empty for all pages. Multi-page PDFs produce a ZIP.

Why Convert ORF to TIFF?
TIFF is lossless and universally read by imaging and document systems, which is exactly what an archive needs: the copy has to outlast the software that made it. Note that Olympus sold its camera division in 2021 and the bodies now ship as OM System, but the file format and the .orf extension carried straight over.
How to Convert ORF to TIFF
Upload your ORF file. Files up to 50 MB are supported.
The RAW is demosaiced and written to TIFF with lossless LZW compression.
Download the TIFF. Every professional imaging tool will open it without Olympus software.
Quality Note
The TIFF is written losslessly with LZW compression, so it is identical to the decoded image. Expect roughly three times the ORF's size, since RAW is itself compressed.
