Best Practices for CR3 to PPM Conversion

  • →Before converting CR3 to PPM, 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 PPM — you cannot recover detail lost during lossy compression
