Why Convert ORF to ICO?
A favicon has to read at 16 pixels, so the useful work is choosing which part of the frame survives. The multi-resolution ICO then lets each context pick its own size. 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 ICO
Upload your ORF file. Crop to a single subject first if you can — a full frame is unreadable at 16 pixels.
The RAW is decoded and rendered at 16, 32, 48 and 256 pixels, all packed into one ICO.
Download the ICO and drop it at your site root as favicon.ico.
Quality Note
The ICO holds 16, 32, 48 and 256 pixel entries. At 16 pixels only one bold shape survives, so crop to a single subject before converting rather than shrinking the whole frame.
