About ORF (OLYMPUS) to APNG Conversion
ORF (introduced 2004) and APNG are both image formats, but they differ in important ways. ORF is Olympus's RAW photo format with full sensor data. APNG is a widely used file format.
When you convert ORF to APNG, the goal is to convert between formats quickly. Converting ORF to APNG maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.
Your ORF file is decoded and re-encoded as APNG. The conversion involves 4 steps: (1) your orf file is uploaded and validated, (2) the file is decoded (parsed into its raw data), (3) the data is re-encoded in apng format, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you When you need a APNG file. For the opposite direction, CocoConvert also supports APNG to ORF conversion.
