Troubleshooting CR3 to HEIF Conversion

  • !Converting CR3 to HEIF gives blurry output → increase the quality setting before conversion
  • !Colors look different in HEIF than CR3 → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → HEIF uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in CR3 turned white in HEIF → HEIF may not support transparency
