Best Practices for ARW to ORF Conversion

  • →Before converting ARW to ORF, decide whether you need maximum quality or smallest file size — this determines which format truly fits
  • →Save a master copy in a lossless format before converting to ORF — you cannot recover detail lost during lossy compression
  • →Check the color profile: ARW images may use a wider gamut than ORF supports, causing a visible shift after conversion
  • →Resize images to the final display dimensions before converting — this avoids unnecessary processing of oversized files
  • →Run a single test conversion first to verify quality meets your standards
  • →Strip unnecessary metadata to reduce file size after conversion
